一、概述为适应现代航天、航空、深海和高压等技术的需要,近年来不断探索轻质、高强、耐高温的新材料,促使材料科学和材料工业取得了很大的进展。颇有前途的工程结构用纤维补强复合材料的研制已引起人们的极大注意,如硼、碳纤维补强的复合材料已显示了强度高,弹性模量高,高温性能好和密度低等特性,在民用和国防工业,特别是在航空和航天领域内,将日益获得广泛的试用。
I. Overview In order to meet the needs of modern aerospace, aviation, deep-sea and high-pressure technologies, continuous exploration of new materials of light weight, high strength and high temperature in recent years has prompted material science and material industries to make great strides. Promising engineering structure with fiber reinforced composites has drawn great attention to the development of people, such as boron, carbon fiber reinforced composites have shown high strength, high modulus of elasticity, high temperature performance and low density characteristics , Will be increasingly widely piloted in civilian and defense industries, particularly in the aerospace and aerospace fields.
