摘要
采用缠绕编织方式制备出缠绕型多孔钛材料,并系统地研究高径比对其力学行为的影响。结果显示高径比越小的样品,其弹性模量和屈服强度越大,能量吸收能力也越强。高径比越大的样品其理想能量吸收率在上升阶段上升的越快,但也更快的进入到衰减阶段,导致其最大理想能量吸收率较小。高径比为1的样品其最大理想吸收率比其他三个样品都要大。
The porous titanium with entangled wire structure is prepared by twining and weaving,the effect of aspect ratio on the mechanic properties is investigated. The results show that the lower the aspect ratio of specimens,the higher the Young＇s modulus and yield strength and energy absorption capacity.The ideal energy absorption efficiency of specimens with high aspect ratio is increased fast at the rising stage,but it reaches attenuating stage early,so the maximum ideal energy absorption efficiency is relatively small. The maximum ideal energy absorption efficiency of the sample with the aspect ratio 1 is bigger than that the other three samples.
