The scientist’s study of bamboo mechanical test show that the bamboo shrinkage is small and very flexible and tough, The parallel grain compressive strength 800kg/cm2,the parallel grain tensile strength 1800kg/m2, Among them, the parallel grain tensile strength of bamboo reaches 2833 kg /cm2, have the reputation of “plant steel”.
