摘要： 本文研究了短切碳纤维增强LAS玻璃-陶瓷（以下简称Csf／LAS）复合材料的制备工艺以及纤维长度、取向对其力学性能的影响．获得了短切碳纤维均匀分散并取向排列的复合材料，用扫描电子显微镜和光学显微镜观察了复合材料的断口形貌和显微结构．研究发现短切碳纤维增强LAS玻璃-陶瓷的主要强韧化机理是载荷传递和纤维拔出．

Abstract: The fabrication process of short chopping carbon fiber-reinforced LAS glass-ceramic matrixcomposites and tke effect of fiber length, orientation on the mechanical properties of tke composites were strudied.Tke composites witk fiber dispersed homogeneously, oriented directionally were obtdsed. Microstructureand fracture surface of tke composites were exhaned by optical microscope and SEM. It is conduded thatthe main toughening and strengthening meckanisms are based on load transfer and fiber pullout.
