据粉末金属产品公司网站报道,该公司研制出低成本、高比强、良好加工性的结构金属复合材料——SCom PTM。与蜂窝和整体刚性板材料相比,这种复合材料结构紧密、具有优良的比强度和吸能性。SCom PTM独特的结构指在金属基体中充满空心球/微气球阵列。按照基体的性能要求,这些微气球可以是玻璃、莫来石(铝酸盐形成的矿石)、氧化铝、Si C或C。这种复合材料的密度是纯金属合金的25%~75%,模量是母金属合金的1/4~1/2,力学性能是母合金的50%~75%。这种复合材料的突出特点是吸能性,不论是大块
According to the Powder Metal Products website, the company has developed the SCom PTM, a structural metal composite that is low cost, high specific strength and good workability. This composite has a compact structure with superior specific strength and energy absorption compared to honeycomb and monolithic rigid board materials. SCom PTM unique structure refers to the metal matrix filled with hollow ball / micro-balloon array. These microballoons may be glass, mullite (aluminate-forming ore), alumina, SiC or C, depending on the substrate’s performance requirements. The density of the composite material is 25% -75% of the pure metal alloy, the modulus is 1/4 ~ 1/2 of the parent metal alloy, and the mechanical property is 50% -75% of the master alloy. The salient feature of this composite is energy absorption, whether large or large
