研究了芳炔基酚醛树脂（AEP）作为复合材料基体的适用性。溶解性和流变性能测试表明,AEP树脂工艺性良好,适合于模压等多种成型工艺。采用差示扫描量热分析仪（DSC）和红外光谱仪（IR）研究了树脂的固化行为,确定了固化制度。热重分析仪（TGA）的结果表明,与传统酚醛树脂相比,AEP树脂耐热性和炭炭性能明显提高,5%失重温度为421℃,氮气氛围900℃的残重值约为79%。石英布/AEP树脂复合材料的力学性能测试结果表明,其室温和高温力学性能明显优于聚芳基乙炔树脂（PAA）复合材料。
The suitability of aryl ethyne-functional phenolic resin（AEP） as matrix of composites was evaluated.The results of solubility and rheology experiment show that AEP possesses good processing capability.The cure characterization was done with differential scanning calorimetry（DSC） and Fourier transform infrared spectrum（FT-IR）,and the cure schedule was determined.Cured AEP resin shows significantly improved thermal properties,in relative to novolac-type phenolic resin.The onset temperature of storage modulus is 350 ℃,5% mass loss temperature is 421 ℃,and the char yield at 900 ℃ in nitrogen is 79%.In comparison with polyarylacetylene（PAA）-matrix composites,the composites of AEP resin present much higher mechanical strength both at low and high temperature.
