摘要
在不同温度和压力的热压罐环境下,测试聚甲基丙烯酰亚胺泡沫(PMI)的尺寸稳定性,建立尺寸变化率与温度、压力、时间的关系,并结合不同固化参数下碳纤维增强树脂基复合材料的机械性能,得到外形和内部质量满足要求的PMI泡沫夹芯复合材料。
The dimension stability of PMI foam was tested in autoclave environment with different temperature and pressure, aiming to establish a relation among dimension change rate, curing temperature, pressure and time.Combining with mechanical property of carbon fiber reinforced composite under different curing parameters, PMI foam core sandwich composite was prepared, which met the requirement of shape and internal quality.
