A rotary engineâs housing is a simple epitrochiod of two circles. The rotor spins eccentrically inside the housing, thus changing the volume of three spaces (chambers) formed between the two. Rotary engines share the same four-stroke sequence of piston engines: intake, compression, power, and exhaust.
Fibre-reinforced plastic. Fibre-reinforced plastic (FRP) (also called fibre-reinforced polymer, or fiber-reinforced plastic) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used.
Glass fiber reinforced plastic (gfrp) and other composite materials have been used for high performance automobiles and sports cars for over 25 - 30 years. There is no inherent deficiency or shortcomings in the mechanical properties that can be achieved using composite materials.
