摘要
利用真空热压烧结工艺,以一种新型的材料排列方式(复合材料前半部分为Ti/Al_(3)Ti层状复合材料,后半部分在Ti/Al_(3)Ti层之间扦插玻璃纤维),成功利用玻璃纤维强化Ti/Al_(3)Ti层状复合材料。在同样的工艺条件下,通过改变玻璃纤维的层数(玻璃纤维的体积分数),探究玻璃纤维的层数对复合材料静态压缩性能、静态拉伸性能的影响。研究结果表明:随着玻璃纤维层数的增加,复合材料的静态压缩性能与静态拉伸性能都有提升,但不是简单的正相关,而是前期提升效果明显,后期提升效果不明显;同时,复合材料的静态压缩性能在沿垂直于叠层方向测试时,提升效果要比沿平行于叠层方向测试时明显。
The Ti/Al_(3)Ti laminated composites was successfully strengthened with glass fibers using a new material arrangement(the first half of the composite material is a Ti/Al_(3)Ti laminated composite material,and the second half is inserted between the Ti/Al_(3)Ti layers),using a vacuum hot pressing sintering process.Under the same process conditions,the influence of the number of layers of glass fibers on the static compression properties and static tensile properties of composite materials was explored by varying the number of layers of glass fibers(the volume fraction of glass fibers).The results show that with the increase of the number of glass fiber layers,the static compression properties and static tensile properties of the composite materials are improved,but they are not simply positive correlation,but the improvement effect is obvious in early stage and not obvious in the later stage.At the same time,the static compression performance of the composites is improved more significantly when tested along the direction perpendicular to the lamination than along the direction parallel to the lamination.
