Beth yw nodweddion tanciau bitwmen?
What are the characteristics of bitumen tanks:
(1)Lightweight and high strength
The density is between 1.5~2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close to or even exceeds alloy steel, and the specific strength can be compared with high-grade carbon steel.
Therefore, it has special effects in aviation, rockets, space quadcopters, llongau pwysau, a chynhyrchion eraill sydd angen lleihau eu pwysau eu hunain. Gall cryfder ymestyn, plygu a chywasgu rhywfaint o FRP epocsi gyrraedd mwy na 400mpa.
