Abstract

Low velocity impact tests were conducted on ultra high molecular weight polyethylene (UHMWPE) laminates having different ply angle. The tests were conducted at various temperatures using steel impactor having 16mm diameter and hemi spherical shape. The selected impact energies are in the range of 50 to 250 Joule. The performance of the composites was compared with respect to peak force, maximum displacement and back face deformation. Results indicated that with increase of temperature, the contact duration increased whereas deceleration was reduced. Various failure mechanisms involved in energy absorption were also addressed.

温度和铺层角对超高分子量聚乙烯(UHMWPE)层合板低速冲击性能的影响

对不同铺层角的超高分子量聚乙烯(UHMWPE)层压板进行了低速冲击试验。试验采用直径16mm的半球形钢制冲击器，在不同温度下进行。所选择的冲击能量在50到250焦耳之间。对复合材料的峰值力、最大位移和背面变形进行了比较。结果表明，随着温度的升高，接触时间增加，减速减小。还讨论了能量吸收过程中的各种失效机制。
