一、背景第二次世界大战后期,为了增加雷达罩透波率,研制成玻璃钢。没料到这类复合材料后来由于它有高的比强度和比刚度而成为使钢、铝、钛等金属有时相形见拙的新型结构材料,而且随着其组分材料的不断创新,新工艺的出现,实现更大程度的可设计性,成本一再下降,其发展速度越来越快,其品种也越来越多。有聚合物基的,金属基的和陶瓷基的复合材料;有连续纤维的,短切纤维的,长短混杂或品种混杂纤维的复合材料;有在3000℃左右下能抗烧蚀的碳碳材料;有在
First, the background After the Second World War, in order to increase the radome penetration rate, developed into FRP. It was unexpectedly expected that these composites will later become new structural materials that sometimes make metals such as steel, aluminum and titanium appear clumsy due to their high specific strength and specific stiffness, and as their component materials continue to innovate, the new technology The emergence of a greater degree of design, the cost of declining again and again, its growing faster and faster, its variety is also more and more. Polymer-based, metal-based and ceramic-based composite materials; with continuous fibers, chopped fibers, the length of the hybrid or hybrid varieties of fiber composite material; at about 3000 ℃ ablation of carbon-carbon materials ;There are at
