复合材料成型用轻质高强水溶性芯模制备与性能OA北大核心CSTPCD
Preparation and Properties of Lightweight and High-Strength Water-Soluble Core mold for Composite Molding
以聚乙烯吡咯烷酮水溶液为胶黏剂,空心玻璃微珠、石膏和石墨为基体材料,采用热烘干法制备1种用于复合材料成型的轻质高强水溶性芯模,研究了胶黏剂含量、基体材料对水溶性芯模的力学性能和水溶速率的影响,研究了改性方法对水溶性芯模的力学性能的影响,采用扫描电子显微镜(SEM)对改性水溶性芯模的微观形貌进行观察,对其改性机理进行初步探索.结果表明:水溶性芯模的密度为0.46～0.58 g/cm3.高温处理以及不同尺度粒径玻璃微珠的复配是有效改性手段,水溶性芯模…查看全部>>
A lightweight and high-strength water-soluble core mold for composites was prepared by hot-air drying method using aqueous solution of polyvinylpyrrolidone as the adhesive and hollow glass beads,gypsum and graphite as the matrix materials.The effects of adhesive content and matrix material on the mechanical properties and dissolution rates of the water-soluble core mold were investigated.The effect of modification methods on the mechanical properties of wate…查看全部>>
