Abstract

In this paper, a new diamond–silicon carbide ceramic composite material—Ideal—is studied and its mechanical characteristics are determined. For the first time, a comprehensive determination of Poisson’s ratio, shear modulus, bulk modulus, and transverse sound velocity is carried out. Poisson’s ratio is in the region of 0.008 to 0.01, which, in turn, indicates the absolutely brittle nature of the failure of the Ideal ceramic under loading. The criteria that allow evaluating different materials used for body armor are calculated.

理想陶瓷（金刚石-碳化硅复合材料）机械特性的测定

摘要

本文研究了一种新型金刚石-碳化硅陶瓷复合材料——Ideal——并测定了其力学特性。首次对泊松比、剪切模量、体积模量和横向声速进行了综合测定。泊松比在 0.008 至 0.01 范围内，这反过来表明理想陶瓷在负载下失效的绝对脆性。计算了允许评估防弹衣所用不同材料的标准。
