摘要
在多年酚醛模压复合材料制品研制工作中,发现少数制品在不同时期有大小不等、深浅不一的裂纹出现,严重影响了制品质量和使用。本文通过对酚醛模压复合材料制品力学与热学性能、制品裂纹出现特点等进行分析,阐述了裂纹产生根本原因,接着深入阐述了制品应力种类及其产生原因,最后阐述了应力、裂纹对制品的影响等;此外,还阐述了应力对制品宏观影响表现形式等。
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.
