摘要
以碳纤维和铜纤维为原料制备了3维4层深交联机织物,将酚醛树脂和其他填料组成树脂体系,并与深交联织物进行复合成型,制成3维深交联摩擦材料。通过改变织物纬向的铜纤维含量及位置获得4种深交联摩擦材料,探究不同位置和含量的铜纤维对摩擦材料在纬向弯曲性能的影响。结果表明:摩擦材料的弯曲性能随着铜纤维含量的增加而减小;当铜纤维在摩擦材料预制体中间层时,会降低复合材料的弯曲性能。材料的破坏模式具体表现为树脂基体的碎裂,以及纤维的抽拔及断裂。
The four-layer three-dimensional angle interlock carbon/copper woven reinforced phenolic resin compos- ites were designed and prepared. Four different structures of 3-D angle interlock woven composites were made by changing the copper fiber content and position in the weft direction. The influence of different location and content of copper fiber on weft bending property of composite was studied. The result showed that bending property of composite decreased with the increase of copper fiber content. When the copper fiber in the middle layers of 3-D angle interlock woven performed poly- mer, the bending property of the composite was reduced. The brittle failure, which specifically performances as the fragmentation of resin matrix and the extraction and breakage of fiber,was the main failure mode of composite.
