采用基体浆料浸渍纤维束、缠绕成型、层叠并热压的方法获得了强、韧而且致密的碳纤维增强钡长石基复合材料。在热压期间,基体中的单斜相钡长石由玻璃态钡长石原位转变生成。单向碳纤维增强钡长石基复合材料表现出良好的力学失效特性,在室温三点弯曲实验中具有普遍的纤维拔出。抗弯强度和断裂韧性分别为359±20MPa和8.3MPa.m1/2。
A strong, tough and compact carbon fiber-reinforced celite composite was obtained by impregnating the fiber bundles with the matrix slurry, winding, laminating and hot-pressing. During hot pressing, the monoclinic celsian in the matrix is formed by in situ transformation of glassy celsian. The unidirectional carbon-fiber-reinforced barium-feldspar composite exhibits good mechanical failure characteristics and has universal fiber pull-out in room temperature three-point bending experiments. The flexural strength and fracture toughness were 359 ± 20 MPa and 8.3 MPa.m1 / 2, respectively.
