Practice GATE ME glass in the app →In a Fiber-Reinforced Composite (FRP), the PRIMARY function of the FIBERS is to:A BASIC requirement for a matrix material in FRP is:Of these common FRP reinforcing fibers — Glass, Carbon, Kevlar (Aramid), Boron — which has the HIGHEST SPECIFIE-glass vs S-glass: the difference is:KEVLAR (Aramid) fibers exhibit which unique property among common composite reinforcements?Among matrices, THERMOSETS (e.g., epoxy, polyester) differ from THERMOPLASTICS (e.g., PEEK, nylon) by:Boron fibers were historically used in aerospace but have largely been displaced by carbon fibers. The main reGlass fiber for FRP is typically manufactured by:Carbon fiber is produced by HEAT TREATMENT (pyrolysis) of which precursor?SILICON CARBIDE (SiC) fibers are particularly useful in METAL MATRIX COMPOSITES (MMCs) because:ALUMINA (Al₂O₃) fibers in composites are used primarily because:In a FILLED COMPOSITE (filler + matrix), the FILLER's typical role is to:Common resin (matrix) families used in PMC are EPOXY, POLYESTER, and VINYL ESTER. Of these, EPOXY is preferredA "SIZING" on glass fiber serves what dual function?MULTIPHASE fibers (e.g., carbon-core with SiC outer sheath) are designed to:Among "fiber forms" used to lay up composites, common formats include:Modulus of typical CARBON fibers is approximately:Tensile strength of typical CARBON fibers ranges roughly:
