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.
Basalt Fiber Reinforced Polymer (BFRP). Basalt fibers have higher tensile strength than E-glass fibers but lower than S-glass, however, its cost is near the cost of E-glass. It has much better resistance than E-and S-glass to the alkalies in concrete.-glass is the most commonly used fiber. It has high electrical insulating properties, good heat resistance, and has the lowest cost. S-Glass fibers have higher heat resistance and about one-third higher tensile strength than E-glass.
