　　碳纖維增強塑料（CFRP）是一種復(fù)合材料,其特點為強度和剛度較高,而且重量較輕,從而使其極前途。也是因為這些特性,越來越多結(jié)構(gòu)材料使用CFRP,特別是在航天工業(yè),其重量輕,而具有很強的結(jié)構(gòu)完整性。與金屬不同,復(fù)合材料具有各向異性特性,這意味著FRP在不同方向的行為取決于纖維增強效果而產(chǎn)生不同的結(jié)果,而大凡在X和?平面上,FRP是強的。當(dāng)沒有?平面加固,使?方向缺乏負載阻力,如沖擊。但分層可能發(fā)生在層內(nèi),這嚴重降低了這些復(fù)合材料的性能,特別是抗壓強度。由于用于基質(zhì)的熱固性材料（即環(huán)氧樹脂）的性能,FRP復(fù)合材料也非常脆弱�；w的脆性不允許FRP消散沖擊能量。因此,提高基體的韌性能夠提高FRP從低能量沖擊中吸收沖擊能量的能力。為了提高抵抗低能沖擊的分層能力,首先認為提高環(huán)氧樹脂基體的韌性就會解決這件問題,還研究了斷裂面的微結(jié)構(gòu)以及增韌機理。新增橡膠改性環(huán)氧樹脂也是一種提高韌性的方法,而建立了橡膠改性環(huán)氧樹脂的基礎(chǔ)。同時加入少量的橡膠,從而提高不穩(wěn)定機械性能的韌性。近年來,對碳納米管（CNTs）改性環(huán)氧樹脂已經(jīng)有許多科學(xué)家研究。CNTs具有較高的比強度和剛度,并且相信能夠提高韌性而不降低環(huán)氧...
