| 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. |
