碳纤维增强杂萘联苯聚醚酮或杂萘联苯聚醚砜复合材料
摘要：
碳纤维增强杂萘联苯聚醚酮或杂萘联苯聚醚砜复合材料，它涉及碳纤维增强杂萘联苯聚醚酮复合材料和碳纤维增强杂萘联苯聚醚砜复合材料。本发明由以下组分按照体积含量百分比组成：碳纤维50～70％、杂萘联苯聚醚酮或杂萘联苯聚醚砜30～50％。由于PPEK和PPES的玻璃化转变温度分别为263℃和305℃，CF/PPEK和CF/PPES复合材料在250℃时的拉伸和弯曲强度及模量均达到60％以上，说明这两种复合材料均具有优异的高温力学性能，可以作为结构材料在高温条件下使用。
摘要（英）：

The present invention relates to carbon fiber reinforced composite heteronaphthyl biphenyl polyether ketone material and carbon fiber reinforced composite heteronaphthyl biphenyl polyether sulfone material. The present invention consists of carbon fiber 50-70 vol%, and heteronaphthyl biphenyl polyether ketone or heteronaphthyl biphenyl polyether sulfone 30-50 vol%. Heteronaphthyl biphenyl polyether ketone and heteronaphthyl biphenyl polyether sulfone have glass transmission temperature of 263 deg.c and 305 deg.c separately, both carbon fiber reinforced composite heteronaphthyl biphenyl polyether ketone material and carbon fiber reinforced composite heteronaphthyl biphenyl polyether sulfone material have tensile strength, bending strength and modulus at 250 deg.c over 60 %, so that these two kinds of composite material have excellent high temperature performance and may be used as high temperature structural material.
