【摘要】：利用浸漬法制備連續(xù)碳纖維增強(qiáng)聚醚醚酮(CF/PEEK)預(yù)浸帶,對其成型溫度、行進(jìn)線速度進(jìn)行研究,并測試了CF/PEEK預(yù)浸帶的熱脹系數(shù)、拉伸性能,利用SEM掃描電鏡觀察CF/PEEK預(yù)浸帶內(nèi)部界面結(jié)合狀態(tài)。結(jié)果顯示,預(yù)熱區(qū)、熔融熱壓區(qū)溫度分別控制在110~130℃和220~370℃,預(yù)浸帶行進(jìn)線速度控制在2 m/min時,制備的預(yù)浸帶性能較好;在-150~+150℃范圍內(nèi),CF/PEEK預(yù)浸帶線脹系數(shù)為0.5×10-6/K,并隨著纖維體積分?jǐn)?shù)增大而減小;CF/PEEK預(yù)浸帶最大拉伸強(qiáng)度達(dá)到1.81 GPa;SEM掃描電鏡顯示碳纖維與PEEK界面結(jié)合良好。研究顯示,CF/PEEK預(yù)浸帶制備工藝參數(shù)可行,CF/PEEK預(yù)浸帶性能較好,具有工程應(yīng)用價值。

[Abstract]:The continuous carbon fiber reinforced polyether ether ketone (CF/PEEK) prepreg belt was prepared by impregnation method. The molding temperature and travel line velocity of the continuous carbon fiber reinforced polyether ether ketone (CF/PEEK) prepreg belt were studied. The thermal expansion coefficient and tensile properties of the prepreg belt were measured. The interfacial bonding state of the prepreg belt was observed by SEM scanning electron microscope. The results show that the properties of the prepreg zone are better when the temperature of the prepreg zone is controlled at 110 脳 130 鈩，
