什么是复合材料? What is a ‘Composite’?
广泛定义:两种材料的结合,仅一种材料不能单独使用 Broad definition: a combination of two materials that can do things neither could do alone
工作定义:一种强韧的或坚硬的物质(经常是一种纤维) 能够为基质(通常是树脂)提供重要的机械性能,从而保 护纤维免受强度和环境的损坏。 Working definition: a strong or stiff ‘reinforcement’ (usually a fiber) that provides key mechanical properties to a ‘matrix’ (usually a resin) that in turn protects the fiber from stresses and environmental damage
