| Abstract: | During studying and manufacturing of the molded phenolic composite products for many years, some cracks which have different size and depth are found on some products at different period, and they affects seriously the quality and application of the products. By analyzing the characteristics of cracks, the mechanical and thermal properties of molded phenolic composite products, the paper sets forth that the basic mason of the cracks is unbalance of the material stress and its tensile strength, and discusses the kinds of the stress and reasons in detail. At last the influence of crack and the stress on the products is described. |
