摘　　要：制备了高分子量热固性酚醛树脂,直接利用湿法纺丝制得酚醛纤维。制得的酚醛纤维拉伸强度最大为101.2 MPa,断裂伸长率约为2.6%,初始分解温度在300℃以上,热塑性酚醛树脂与甲醛物质的量比为1:3时所得的酚醛纤维在800℃条件下残炭率最高,为45.8%。The high molecular weight thermosetting phenolic;resin is prepared,and phenolic fiber is prepared by wet spinning directly.The initial decomposition temperature is above 300℃,the maximum tensile strength of the phenolic fiber is 101.2 MPa,and the elongation at break is 2.6%.When the molar ratio of thermoplastic phenolic resin to formaldehyde is 1:3,the carbon residual rate of phenolic fiber obtained at 800℃ can reach the highest of 45.8%.
