固体推进剂增材制造技术的研究进展与展望
Research progress and prospect of additive manufacturing technology for solid propellant
摘要
Abstract
Additive manufacturing technology is based on the principle of layered manufacturing,which transforms complex 3D machining processes into planar machining processes,achieving layer-by-layer manufacturing of solid propellant grain from points,lines,surfaces,to bodies.At present,numerous scholars at home and abroad have conducted extensive research on solid propellant additive manufacturing technology in terms of processes,equipment,formulations,and other aspects.This article introduces seven typical additive manufacturing technologies based on the latest research results at home and abroad in the past five years,and elaborates in detail on the forming principles of vat photopolymerization technology,material extrusion technology,and binder jetting technology,as well as their application status in the field of solid propellants;summarized the latest research progress of solid propellant additive manufacturing technology in terms of process equipment and formulation systems,as well as the overall trend towards intelligent manufacturing;based on the analysis of its technological progress and development trends,four prospects are proposed as follows:continuing to overcome the technical difficulties of binder jetting,strengthening the integrated application of simulation in practical production,developing self-healing adhesives suitable for additive manufacturing,and introducing heat stimulated shape memory polymers to manufacture geometrically complex solid propellants with programmable deformation and on-demand property-changing capabilities.关键词
