Composite Materials (Composite materials), is based on a matrix material (Matrix), a material for the reinforcement (reinforcement) material Performance on a variety of materials in each other, creating synergies, so that the integrated performance of composite materials than the original composition of material to meet a variety of different Matrix material is divided into two major categories of metal and non- Commonly used in metal matrix aluminum, magnesium, copper, titanium and its Mainly non-metallic matrix of synthetic resin, rubber, ceramics, graphite, carbon and so Main reinforcement glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fibers, asbestos fibers, whiskers, wires and other fine-grained and The use of composite materials can be traced back to ancient From ancient times to enhance the use of straw and clay for centuries has been the use of reinforced concrete formed by the two types of composite The 20th century, 40's, due to the needs of the aviation industry, the development of glass fiber reinforced plastic (commonly known as glass fiber reinforced plastic), a composite material from the After the 50's, have developed a carbon fiber, graphite fibers and boron fibers high strength and high modulus 70's a aramid fiber and silicon carbide These high-strength, high modulus fibers with synthetic resin, carbon, graphite, ceramic, rubber and other non-metallic substrate or aluminum, magnesium, titanium and other metal matrix composites, which constitute the composite material [Edit this paragraph] Classification Is a mixture of composite Composite materials into their component metals and metal composites, non-metallic composite materials and metals, non-metallic and non-metallic composite According to their structural characteristics are divided into: ① fiber composite Body will be placed in a variety of fiber-reinforced matrix--《复合材料学报》2004年05期

reduced CTE for high loadings：为了较高的承载力降低（减小）热膨胀系数CTE：热膨胀系数（Coefficient of Thermal Expansion）；high loading：高承载力（高载荷）

Wooster等报告了微米级石英/氰酸酯复合材料，在高填料量时机械性有所改善，热膨胀系数有所下降。Wippl等研究了用高填料量石英、氮化硅、和氧化铝作为增强材料的耐高温热固性塑料（双马来酰亚胺，聚酰亚胺，氰酸酯和）,体积分数达80％时CTE可降低至 15 ppm/℃。
