面向太空制造的复合材料3D打印与回收利用
3D Printing and Recycling of Composites for Space Manufacturing
摘要
Abstract
In response to the resource scarcity issues in space manufacturing,two technologies for recycling three-dimensional(3D)printed continuous fiber reinforced composites are proposed.The reverse melting drawing method is adopted to recycle the carbon fiber reinforced polyether ether ketone(CF/PEEK)composites.An innovative overcooling 3D printing process for polyphenylene sulfide(PPS)self-reinforced composites is developed,enabling the manufacturing and recycling of self-reinforced composites.The evolution laws of the microstructure and mechanical properties of the composites before and after recycling are studied.The recycled prepreg filaments are reprinted to obtain CF/PEEK samples,with flexural strength and modulus improved by 4.8%and 50.8%,respectively,compared with the original ones.The flexural strain of the samples printed by the recycled PPS self-reinforced composites is increased by 13.8%compared with that printed by the original PPS composites,and the toughness is significantly enhanced,achieving non-degradable recycling.Overall,a full lifecycle recycling and reuse strategy for 3D printed composites for space manufacturing is explored,providing support for the future development of space manufacturing.关键词
