【正文】 a high degree of crosslinking is referred to as a polymer network.4. In polymers, however, the molecular mass may be expressed is terms of degree of polymerization, essentially the number of monomer units which prise the polymer.Unit16：工程材料 生成的材料增強(qiáng)混凝土 金屬基復(fù)合材料陶瓷基復(fù)合材料 三明治結(jié)構(gòu)1. 例如，多相金屬在微觀層次上是復(fù)合材料，但廣義上講，復(fù)合材料這個(gè)術(shù)語，指的是兩個(gè)或多個(gè)不同材料之間依靠機(jī)械力結(jié)合而形成的材料。2. 許多情況下，復(fù)合材料有一個(gè)本相：它是連續(xù)的，叫做基體，還有一個(gè)分散的、不連續(xù)相，叫做增強(qiáng)相。3. 先進(jìn)復(fù)合材料是樹脂和纖維的結(jié)合，通常是碳纖維/石墨、凱夫拉纖維、玻璃纖維和樹脂。纖維提供高剛度，周圍的聚合物樹脂基體將整個(gè)結(jié)構(gòu)固定起來。4. 如果復(fù)合材料被正確地設(shè)計(jì)和加工，它具備增強(qiáng)體的強(qiáng)度、基體的韌性，獲得所需要的結(jié)合的性質(zhì)，這種性質(zhì)是任何傳統(tǒng)單一材料所不具備的。Composite materials reinforced materials Glass fiber matrix materials Strengthening mechanism traditional materials posite retains its own distinctive properties that cannot be achieved by any of the ponents acting alone. posites are two thirds the weight of aluminum, and two and a half times as stiff. Composites are resistant to fatigue damage and harsh environments, and are repairable. the concept of posites, reinforced plastic, metalmatrix posite, ceramicmatrix posite and concrete, etc, are all posites. fiberreinforced posites, the fiber is the primary load bearing ponent. Fiberglass and carbon fiber ponents are examples of fiberreinforced posites.
