STUDY ON LMPROVEMENT MEASURES FOR CRACKS IN THE MOLDED PHENOLIC COMPOSITE PARAS

The characteristics and the reason analysis of cracks in the molded phenolic composite parts, the kinds of stress and its cause of formation are described in this paper. Then the improvement principles and improvement ideas are put forward according to the cause, and more than ten improvement measures are taken to relieve the product stress in five aspects, such as the structure design, the mold design, the process, the post treatment and the store condition. The improvement measures are proved effective in reducing the cracks by experiments and are helpful for the manufacture of the products.
