Practice GATE ME reinforcement in the app →A composite material is BEST defined as:Composite materials are most commonly classified at the FIRST level by:Polymer Matrix Composites (PMCs) and Carbon-Carbon Composites are both subcategories of:In a fiber-reinforced composite, a "DISCONTINUOUS" or short-fiber composite is one where:Why must fibers in a fiber-reinforced composite be SUPPORTED by the matrix?Sandwich structures (honeycomb core between two facesheets) are an example of which composite category?Concrete (cement matrix + aggregate stones) is an example of which composite category?Carbon-Fibre Reinforced Plastic (CFRP) is an example of:The image below shows what type of composite reinforcement?
, the matrix can be EITHER thermoplastic OR thermoset. The KEY difference iThe PRIMARY drawback of Ceramic Matrix Composites (CMCs) compared to Metal Matrix Composites (MMCs) is:Glass-Fibre Reinforced Plastic (GRP, "fiberglass") is widely used because:The role of the MATRIX in a fiber-reinforced composite is to:In a unidirectional continuous-fiber composite under tension PARALLEL to fibers, the longitudinal Young's moduDirectionally-solidified eutectic composites are produced by:MICROSPHERES (hollow glass spheres) used as filler in composites primarily improve:In a fiber-reinforced composite, ANISOTROPY (direction-dependent properties) is MAXIMUM when:What is the principal advantage of carbon-carbon composites over metal alloys for high-temperature applicationExamples of MATRIX MATERIALS commonly used in PMCs include:The fundamental MOTIVATION for using composites in spacecraft and aircraft is:Why are continuous-fiber composites often described as having "near-zero" ductility compared to metals?
