Fasteners For Advanced CompositesINTRODUCTIONFOREWORD:As an adjunct to the contents of this catalog, especiallyfor those who have had little or no prior experience withrespect to the use of fasteners for sandwich panelShur-Lok has produced a Design Manual covering allthe basic considerations for the selection and application of Sandwich Panel Fasteners. This Manual hasbeen produced by Shur-Lok with assistance from anumber of leading aerospace firms and presents anexhaustive investigation into virtually every aspect ofthe subject complete with many pages of test reportdata. This Design Manual is available upon requestfrom the Shur-Lok Corporation. Simply ask for “Sandwich Panel Fasteners — Design Manual. ”INTRODUCTION:Composites, as addressed in this catalog, are made upof high strength, high-modulus, fiber-reinforced thermostats or thermoplastic resins. Some of the more common reinforcements are: fiberglass, boron, graphite/carbon, and Kevlar /epoxy. Composite structureshave an excellent strength-to-weight or stiffness-toweight relationship in comparison to metallic materials.It is because of these strength and stiffness characteristics and the ease by which a final configuration can beachieved that the use of these materials is greatlyincreasing in the aircraft and aerospace industry.be made of materials considered galvanicallynoncorrosive. If a reaction does occur, the fastenerbecomes sacrificial and literally corrodes away.This reaction not only destroys the integrity of thejoint, but it is also aesthetically undesirable. ShurLok recommends titanium, Inconel, A286, or nonmetallic fasteners for use in graphite-based structures. Materials to avoid are summed up in Table I.TABLE 1 -Material Compatibility With uminum AlloysAluminumAlloy Steel300 Series CRESMonelTi AlloysTi-CbMP 35N (AMS 5758)lnco600 (AMS 5687)A286 (AMS 5731, 5737)PH13-8Mo (AMS 5629)NonmetallicsB. Interference Fit — It is not recommended thatfasteners be installed using an interference fit incomposite structure because slight delaminationoccurs as the fastener is pressed in place. As littleas a few thousandths of interference can result insubstantial strength loss, with no improvement infatigue life. Structural characterization is recommended to evaluate performance.C. Hole Edge Crushing — Since most compositesdo not have transverse reinforcement, i.e., fiber directed through the thickness of the laminates,there is relatively little resistance to crushing (Illustration 1). As crushing occurs, strength is substantially compromised.FASTENING IN COMPOSITES:While in may ways, fiber-reinforced advanced composites are strongerthan metallic structure, they do notrespond well to localized concentrated loading. Fasteners have been developed to address this issue andothers. These other design considerations are outlinedbelow.A. Galvanic Compatibility — This concern is primarily related to material containing carbon fiber. Because of the highly noble character of the graphite,and the fact that the fibers can come in contact withthe less noble metallic fastener, the fastener mustIllustration 11
Fasteners For Advanced CompositesThis results in weight gain and laminate degradation. In cases where holes are required, it may benecessary to avoid this phenomenon.Avoidance of crushing can be achieved by enlarging the “footprint” of the fastener used and closelycontrolling the installation forces.In developing a series of fasteners for fiber-reinforced advanced composites, Shur-Lok has addressedthese related issues. While no one fastener is the totalanswer, Shur-Lok has developed a variety of fastenersthat make the use of these advanced materials apractical reality.D. Vibration Damage — During installation it is important to apply forces into composite lay-upsmoothly. For example, a two-part insert should besqueezed, not hammered together thus avoidingstructural damage induced by heavy shock orvibration.E. Hole Preparation — Of primary importance to anyfastener joint is the preparation of a good installation hole. Unlike metallic structure, compositestend to suffer surface ply splintering, surface plydelamination, irregularities inside the hole, andheat damage while drilling holes. In response tothis problem, Shur-Lok has developed a series ofbonded fasteners that attach to the surface of thesubstrate thereby avoiding the need for holes.TYPES OF FASTENERSShur-Lok has developed three classifications offasteners for fiber-reinforced advanced composites.These classifications are: bonded, bonded-mechanical, and nonmetallic potted. A brief, general description of each type of fastener is written below. For morecomplete information and installation procedures,please refer to the introduction section for each specificfastener.When holes are required, it is important to use theproper drill such as special spade or diamondabrasive impregnated core drills. It may be necessary to back up the entry and exit area of the panelto prevent splintering and delamination (Illustration2).A. Bonded —This is a series of studs and inserts thatare bonded to the surface of the substrate. Thestud series requires no hole and the insert seriesrequires a single hole to allow for nut float and boltprotrusion (Illustration 3).Illustration 3Wood or Other Soft MaterialThese fasteners are available with or without apreattached hot melt or thermoplastic adhesivedisk. Fasteners supplied with the hot melt or adhesive disk are simply installed by heating the fastener to melt the adhesive, removing the heatsource and holding it in place as the adhesivecools. These types of fasteners lend themselveswell to robotic installation.Illustration 2F. Water Absorption — As composite materials aredrilled or machined, the natural sealing process oflamination is disrupted. In areas where fibersbecome exposed, an action may take place inwhich water, fuel, etc. is slowly absorbed throughthe fiber-matrix interface into structure.2
Fasteners For Advanced CompositesB. Bonded/Mechanical — Fasteners of this type usea combination of adhesive and mechanical measures for retention in the structure. In most cases theadhesive is applied to the surface under the fastener flange. In the adjustable insert, however,potting compound is injected through the flangeinto the void in the panel after the part has beenadjusted to the panel thickness.SUMMARY:All of the fasteners presented in this catalog are available in materials compatible with all known compositematerials. These parts are only examples and are notintended to be suitable for all structures. Please consult the Shur-Lok Technical Service Department forfurther suggestions regarding specific applications.Shur-Lok also has an extensive engineering facility toassist in the development and testing of fasteners forspecial applications.Illustration 4C. Nonmetallic Potted — Primarily designed for sandwich panel, this potted type fastener can also workwith thicker composite lay-ups. The primary material is a polyetherimide thermoplastic, which is nonreactive with all current composites and is verylightweight. Installation is accomplished using theindustry-standard Shur-Tab potting process. Aversion with a floating nut element is also availablefor correction of hole misalignment (Illustration 5)Illustration 5All potted style fasteners are supplied with a ShurTab which greatly simplifies the installation procedure. Please refer to the Fasteners for SandwichStructure catalog for information on tab installation.3
Bonded FastenersINTRODUCTIONFasteners in this category include inserts and studswhich utilize surface bonding for structural attachment.Featuring a somewhat larger mounting flange to achieveadequate shear or tensile strength, bonding is accomplished by means of a heat unit applied to the part tomelt the thermoplastic disk under the flange. Fasteners are available with or without this adhesive (or hotmelt) disk. Use of a heat sink greatly reduces thecooling cycle. One floating nut style requires, and isfurnished with, adisposable nonmetallic locating pin toinsure proper positioning with respect to the bolt holein the structure.Bonded StudAttachment of surface bonded fasteners requires onlyminimal preparation, however, certain precautionsshould be observed which are presented in ParagraphE in the General Information on pages 1 and 2 of thiscatalog. Stud attachments do not require a hole in thestructure so that in effect no preparation on the structure is involved. It should also be noted that wheremounting surfaces are glossy, an improved bond maybe achieved by abrading the surface prior to attachment.Bonded Insert4

Bonded/Mechanical FastenersINTRODUCTIONProviding the highest degree of structural integrity, thisfamily of fasteners combines two means of retention inthe panel. Parts in this group employ both surfacebonding and various methods of mechanical retention.The mechanical retention is effected in several ways:Flaring one element of the fastener or by using a pressfit between the mated fastener components. Theadhesive bonding is done first, followed by themechanical method of retention.Bonded Flared InsertBonded Plug and Sleeve

Non-Metallic InsertsINTRODUCTIONWHAT ARE COMPOSITE INSERTS?The SL6300 series composite inserts includeblind threaded, through threaded, clearance bolthole, and blind threaded floating nut element designs. Composite inserts were initially developed toprovide electrochemically compatible inserts forcarbon reinforced composite faced sandwich structures. Composite inserts possess significant advantages over metallic inserts.Material Properties:Composite inserts are fabricated from glassfiber reinforced polyetherimide material. An advanced amorphous thermoplastic, polyetherimidecombines the high performance of exotic specialtypolymers with the economics of engineering thermoplastics. The addition of glass to the base resinincreases mechanical strength, stiffness, heat deflection temperature, flamability, and chemical resistance.Weight Savings:Composite inserts are up to 70 percent lighter inweight than conventional metallic inserts and have aspecific gravity equivalent to most common epoxypotting compounds.Corrosion Resistant:Composite inserts have good environment resistance and are noncorrosive.Thread EngagementIllustration 1SL6302-3 Tensile Strength At Room Temperaturefeature over thirty installation and removal cycles.The first four threads are nonlocking to facilitateinitial thread engagement. The minimum threadlocking torque specified by MIL-N-25027 is obtainedafter the sixth thread engagement. The thread lock isadditive and therefore increases proportionally witheach thread engagement into the insert beyond thefourth thread engagement. This is shown in Illustration 3. The thread lock at full thread engagement onlonger threaded inserts will not exceed the maximumthread locking torque specified by MIL-N-25027.Enhanced Strength:Optimized geometry and inherent material surface properties are combined to produce an insertwith superior insert to potting compound adhesion.Composite inserts will typically produce higherflatwise tensile and shear strengths in lightweightsandwich panels.Unlike metallic inserts, the tensile strength ofthreaded composite inserts increases proportionallywith thread engagement. This is shown in Illustration1.Nonmetallic Thread Lock:Threaded composite inserts incorporate anintegral prevailing locking feature whose durabilitytypically outperforms most metallic thread lockingfeatures. Illustration 2 shows the durability of thisCycle NumberIllustration 2SL6302 Locking Torque Durability
Non-Metallic InsertsConventional Installation:Composite inserts are installed with the aide ofstandard disposable Shur-Tabs . The holes in theadhesive-backed tabs are matched with the holes inthe insert prior to inserting the fastener in the hole.The tab prevents potting compound from overflowinginto the thread area or through hole while alsoassuring flush installation to the panel face skin. (Seepage 43 — 6300 Data)Standardization:Number Of TurnsIllustration 3Locking Torque Vs Thread EngagementSelf-Lubricating:Composite inserts are inherently self-lubricating.This eliminates the need for special platings and dryfilm lubricants used on metallic threaded inserts.Thermal Properties:Polyetherimides high heat deflection temperature contributes to excellent retention of physicalproperties at elevated temperatures. Compositeinserts are also excellent thermal insulators anddisplay low heat release, smoke generation, andtoxicity that qualifies them for use in the interiors ofaircraft built after 1990.Design Configuration:The unique patented ribbed configuration ofShur-Lok’s composite inserts is designed to directthe flow of potting compound around the insert andpromotes optimum adhesion between the insert andpotting compound. Additionally, the ribs serve as astiffener in both axial and radial directions, and theyprovide a mechanical interlock between the insertand potting compound to prevent rotation of theinsert after cure of the potting compound.Composite inserts can replace several costlyspecial metallic inserts. Stainless steel inserts can bereplaced because composite inserts are corrosionresistant. Adding a nonmetallic locking pellet or ringto aluminum inserts is also unnecessary since composite inserts have an integral nonmetallic lock. Theself-lubricating feature makes application of dri-filmlubricants unnecessary.Cleaning:It may be necessary to clean or degrease theface of composite inserts after installation, especiallyif the parent panel is to be painted. The followingcleaning/degreasing agents have been found to becompatible with composite inserts.Alcohols-Methyl, Isopropyl, lsobutylAliphatics-Hexane, HeptaneHalogenated Hydrocarbons-Fully HalogenatedFreonROther-Soap solution, NaphthaNote: Composite inserts should not be cleanedwith partially halogenated hydrocarbons such as1,1,1-Trichloroethane or with ketones such as MEK.Important:The introduction provided about Shur-Lok ’s composite inserts may be considered to be indicativeof representative properties obtainable.
