特別是力學(xué)性能可以成倍的提升。增強(qiáng)改性不僅使力學(xué)性能有了飛躍，同時(shí)還賦予材料優(yōu)異的性能，其特點(diǎn)如下：1、比強(qiáng)度高：所謂比強(qiáng)度高是指材料的強(qiáng)度與相對(duì)密度之比值。通過(guò)增強(qiáng)有些塑料的比強(qiáng)度與金屬相當(dāng)。2、減震性好，過(guò)載安全性好。3、抗疲勞性好：即抗重復(fù)應(yīng)力的性能好。4、耐熱性好：通過(guò)增強(qiáng)，熱變形溫度可大幅提高。5、線(xiàn)膨脹系數(shù)?。河捎诶w維類(lèi)材料的加入，增強(qiáng)材料的線(xiàn)膨脹系數(shù)比塑料本體低很多，因而制品成型收縮率小，可用于制造尺寸精密度要求高的產(chǎn)品。增韌改性PC在塑料中加入增韌劑以提高塑料的耐沖擊性。增韌在改性PC塑料的特點(diǎn)的沖擊強(qiáng)度大幅提高，但同時(shí)拉伸強(qiáng)度、彎曲強(qiáng)度、耐熱性有所下降。阻燃改性PC指向塑料中添加阻燃劑以提高其耐燃燒性。大多數(shù)塑料屬于易燃燒材料，用于電氣、電子設(shè)備的安全性較低，通過(guò)阻燃改性使材料的安全性有所提高。當(dāng)然阻燃改性使得材料的大多數(shù)性能有所降低。合金由兩種或兩種以上的不同塑料共混所得的體系稱(chēng)為塑料合金。制備合金的目的主要是讓不同塑料的組分達(dá)到較好的互補(bǔ)。當(dāng)然有些性能也超過(guò)了任一單獨(dú)組分的性能。汽車(chē)外飾用耐候PC材料的開(kāi)發(fā)及應(yīng)用汽車(chē)外部燈具在使用中直接受到太陽(yáng)光的照射。PC
