【摘要】 通过对氰酸酯树脂进行增韧改性(将改性后的氰酸酯树脂记为CEh基体),改性后的氰酸酯树脂不仅适合湿法纤维缠绕成型工艺,而且CEh基复合材料的耐热性能良好。用CEh基高性能纤维复合材料研究了改性后的氰酸酯基复合材料的耐热性能和吸水性能。研究结果表明,S2/CEh复合材料190℃高温弯曲强度保留率为60%,弯曲模量保留率为96%,吸水率为0.15%。更多还原

【Abstract】 Through toughening modification of cyanate ester( modified CE is marked CEh matrix),CEh matrix is not only applicable to wet filament winding process,but also CEh matrix composites has good heat resistance properties. The study investigated the heat resistant and water-absorptive properties of CEh matrix composites reinforced by high-performance fiber. The results showed that retention rate of flexural strength of the S2/CEh composite materials at 190 was 60% ’ the retention rate of flexural modulus was 96%. In addition, the water absorption rate was 0.15%.更多还原
