F-12纤维/氰酸酯树脂基复合材料力学性能研究

Study on Mechanical Properties of F-12 Fiber/Cyanate Resin Matrixed Composites

采用预浸法缠绕工艺制备了F-12纤维/氰酸酯树脂基复合材料NOL环、层合板和Ф150 mm压力容器,研究了F-12纤维/氰酸酯复合材料的力学性能以及断口微观形貌。研究结果表明,F-12纤维/氰酸酯复合材料的层间剪切强度≤35 MPa,Ф150 mm压力容器特性系数PV/Wc值达到34.22 km,纤维强度转化率达到70.22%,断口破坏形式以F-12芳纶纤维撕裂和微纤化为主。

The NOL rings, laminates and Ф150mm standard pressure vessels of F-12 aramid fiber/ cyanate resinmatrix composites were manufactured by pre-impregnated wind process. The mechanical properties and fracture morphologyof F-12 aramid fiber/ cyanate composites were also studied. The results show that the interlaminar shearstrength（ILSS） was less than 35 MPa,and vessel performance factor （PV / Wc） of Ф150 mm standard pressure vesselswere 34. 22 km. The strength transfer rate of F-12 fiber in Ф150 mm pressure vessels was 70. 22%. The form of fracturesurface mainly reveals tearing and fibrillation of F-12 fiber.
