The fracture toughness of carbon fiber reinforced plastics is governed by the mechanisms: 1) debonding between the carbon fiber and polymer matrix, 2) fiber pull-out, and 3) delamination between the CFRP sheets. [8] Typical epoxy-based CFRPs exhibit virtually no plasticity, with less than 0.5% strain to failure.
[citation needed] For producing carbon fiber higher molecular weight is desired. [ 15 ] In the production of carbon fibers containing 600 tex (6k) PAN tow, the linear density of filaments is 0.12 tex and the filament diameter is 11.6 μm which produces a carbon fiber that has the filament strength of 417 kgf/mm2 and binder content of 38.6%.
[1] [2] The most commonly used composites are fiber reinforced polymers (FRP), [3] using carbon and kevlar fibers. The primary advantage of a COPV as compared to a similar sized metallic pressure vessel is lower weight; COPVs, however, carry an increased cost of manufacturing and certification.
Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English fiber) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass ), carbon (in carbon-fibre-reinforced polymer ), aramid , or basalt .
The European Commission funded a research project, C 3 HARME, under the NMP-19-2015 call of Framework Programmes for Research and Technological Development in 2016-2020 for the design, manufacturing and testing of a new class of ultra-refractory ceramic matrix composites reinforced with silicon carbide fibers and Carbon fibers suitable for applications in severe aerospace environments.

The most common particle reinforced composite is concrete, which is a mixture of gravel and sand usually strengthened by addition of small rocks or sand. Metals are often reinforced with ceramics to increase strength at the cost of ductility. Finally polymers and rubber are often reinforced with carbon black, commonly used in auto tires. [7]
Continuous fiber reinforced thermoplastic, is a composite material that contains high-performance continuous fiber, such as carbon fiber, glass fiber, or aramid fiber that is impregnated in a matrix of thermoplastics like polycarbonates. CFRTP is producible into both tape and sheet formats that can later be formed using thermoforming techniques.
