Technically speaking, they're classified as "partially crystalline aromatic polyesters." Polymer Matrix Composites Polymer matrix composites (PMC) are composed of a matrix from thermoset (epoxies, phenolics) or thermoplastic (polycarbonate, polyvinylchloride, nylon, acrylics) and embedded glass, carbon, steel, or Kevlar fibers. Disclaimer 8. Examples of matri-ces in such composites include aluminum, mag-nesium and titanium. Ceramic matrix composites are a type of composite with ceramics as both the reinforcement and the matrix material. However, these are relatively weak in compression. Thermoplastics are usually reinforced plastics, while thermosets are usually advanced composites. These fibers have high longitudinal tensile strength & moduli. A polymer nanocomposite is simply a composite in which we combine a polymer matrix (which could be thermosetting or thermoplastic) with some kind of nanomaterial. In keeping with conventional polymer composites, there may also be some other form of conventional fibre reinforcement (such as woven carbon fibre) included. In both cases, classification is more a matter of degree than a strict "either-or." Carbon Fiber Reinforced Polymer (CFRP) Composites 3. Sandwich composite is constructed by sandwich foam between two skins of FRP laminates. The reinforcement provides its special properties while the matrix material holds everything together. Particulate composites have a matrix with dispersed coarse particles, to produce unusual properties. Now, the part is heated in an inert atmosphere where molecular components consisting of oxygen, hydrogen and nitrogen are driven off, leaving behind large carbon chain molecule. They are desirable for their outstanding strength to weight ratio. Upon cooling thermoplastics will hold their shape but can be softened and reshaped again upon heating. Automotive vehicles: Examples of polymer matrix composite use include tires and various belts and hoses as well as polymer matrix composite components in automotive bodies. 2. Ceramics can be classified into two classes : 1. 5. The most common use for these composites is in Kevlar, the trade name for an aramid fiber product used in body armor and protective gear. They're composed of different resins that catalyze with one another or with additives to form a viscous liquid. It produces composites of very high specific strength. Fig. As thickness of core is deep, the area moment of inertia of cross-section is enhanced too much, leads to increase in flexure rigidity of sandwich beam which make it suitable to use as beam. vi. Services temperature is limited to 200°C as at high temperature polymer begins to flow. Aramid-based composites are thermosets made up of long fibers of synthetic carbon embedded in an aromatic polyamide matrix. Wide variety of composite manufacturing technique can be used.
