Although carbon fiber and glass fiber composite materials have extremely excellent properties,there are some pollution problems in production,use and waste treatment.In order to solve this problem,a reinforced composite material was prepared from bamboo fiber,and the tensile failure behavior of bamboo fiber reinforced composite was analyzed by taking the stress structure of a certain type of fitness equipment as an example.The results show that the size of discrete unit,the percentage of fiber volume and the distribution of fiber strength can affect the tensile failure behavior of bamboo fiber reinforced composite fitness equipment,but the degree and regularity of the influence are different.
