Fiber-Reinforced Diamond Ceramic Composites

这项研究着眼于生产专门用于结构和摩擦学应用的纤维增强金刚石复合材料的可行性。第一阶段的研究包括通过添加连续的碳化硅纤维增强材料和改善纤维/基体界面来提高金刚石基复合材料的韧性。力学性能，如强度、失效应变和纤维拔出长度由加州大学圣巴巴拉分校材料系的弯曲和拉伸测试确定。长远的目标是开发一种新型的复合材料，它比目前的陶瓷复合材料具有更高的导热系数和更强的耐腐蚀性和耐磨性。

This study looks at the feasibility of producing fiber-reinforced diamond composites specifically for structural and tribological applications. Phase I research involves increasing the toughness of diamond matrix composites by adding continuous silicon carbide fiber reinforcement and by modifying the fiber/matrix interface. Mechanical properties such as, strength, strain-to-failure, and fiber pullout length are determined in bending and tensile testing at the Materials Department, University of California, Santa Barbara. The long term goal is a new class of composite materials which are tough and have high thermal conductivity and more corrosion and wear resistance than current ceramic composites.
