一、引言 FRM是Fiber Reinforced Metal的英文缩写,日译名“纤维强化金属”(中译名“纤维增强金属”),其内容是指采用轻质高强的陶瓷纤维去增强金属基体,即纤维增强金属基复合材料。纤维一般用硼、碳化硅、碳、氧化铝等特别轻质高强且耐热性优异的陶瓷纤维。此外,也有用18—8不锈钢等金属纤维作增强材料的。表1(略,参见上一期学报页)中列出的陶瓷纤维已经工业化生产,在市场上出售,故可作FRM的增强材料使用。如果与一般机械结构用的压延钢材SS41(拉伸强度:约41kg/
I. INTRODUCTION FRM is the English abbreviation of Fiber Reinforced Metal, the Japanese translation of “fiber-reinforced metal” (Chinese translation of “fiber-reinforced metal”), its content refers to the use of lightweight high-strength ceramic fiber to enhance the metal matrix, fiber reinforced metal matrix Composites. As the fiber, boron-based, silicon carbide, carbon, alumina and the like are particularly preferred as the ceramic fiber which is particularly lightweight, high-strength and heat-resistant. In addition, 18-8 stainless steel and other metal fibers are also useful as reinforcements. The ceramic fibers listed in Table 1 (omitted, see previous issue of the journal) have been industrially produced and sold on the market and are therefore used as reinforcing materials for FRM. If it is compared with the general structure of rolled steel SS41 (tensile strength: about 41kg /
