摘要: 采用两种大小不同的粒径制备了一种新型水溶性皮芯结构芯模,并对其成型性、力学性能、水溶溃散性及不同粒径制得芯模表面的粗糙度进行研究,结果表明水溶性皮芯结构芯模具有良好的成型性,强度高,并且在保证表面精度的同时有较好的水溶溃散性,综合了小粒径强度、表面精度高和大粒径水溶性好的优势,表面包覆铁氟龙耐高温胶带成功阻止树脂在复合中浸入芯模,且脱模简单。水溶性皮芯式水溶性芯模工艺可以很好地满足长径比大的芯模的要求,给开口小、长径比大的异形件制备提供了新思路。

Abstract: In order to develop novel hollow composite materials, a new type of skin-core structure of water-soluble core mold was prepared by using sand with different particle size, and the surface roughness of the core mold was studied by its formability, mechanical properties, water-soluble collapsibility and particle size. The results show that the skin-core structure of water-soluble core mold has good formability, high strength, and good water-soluble collapsibility while ensuring surface precision. It combines the advantages of small particle size, light weight and large particle size, and high temperature resistance. The Teflon film successfully prevented the resin from immersing in the core mold in the composite. The gradient particle size water-soluble core mold process can well meet the requirements of the core mold with large aspect ratio, and provides a new idea for the preparation of shaped parts with small opening and large aspect ratio.

Key words: water-solubles, kin-core structure, hollow-composite
