Research of making long bamboo fiber by cracking bamboo

Propagating crack in bamboo is a method of making long bamboo fiber.Bamboo fiber made by the method could meet initially the requirements of textile fibers.Mechanization produce of the method is now an urgent problem.This paper based on laminated structure of bamboo,analyzed the damage form during cracking bamboo fiber with micro-mechanical method,seeking for conditions of cracking bamboo into fiber.Focusing on interlaminar debonding behavior of bamboo,an interlaminar debonding model of bamboo were established with mathematics interpolation method.The main technical parameters were obtained for the equipment design and to achieve the theoretical basis for large-scale production of bamboo fiber.At the same time,a new method was also proposed for studying interlaminar debonding behavior of unidirectional composite.
