Separating mechanism and preparation method of the longer natural bamboo fiber

This paper expounds the present methods of making long natural bamboo fiber and their problems,puts forward a new method to unfasten bamboo fiber,ie hot-machine coupling method invented by the authors.The method is based on the fracture mechanics theory,under the combined force of heat and machine load on bamboo plate,realizes the separation of bamboo fibers by the propagating crack between bamboo fiber and matric.The research mainly analyzed the behavior of making original crack in bamboo and propagating crack as well as their load conditions by macromechanics.Finally,the conditions and main factors to unfasten bamboo fiber by this method was put forward.
