超高强度/模量、长链聚乙烯纤维（Spectra®纤维）复合材料具有吸收射弹动能的非凡能力，已显示出作为轻质装甲材料的巨大潜力。但是这种纤维相对较低的熔点（-145 ° C）引起了人们对在冲击/穿透过程中温度升高对装甲材料性能的影响的担忧。分析了弹体和纤维复合材料在撞击/侵彻过程中的温升情况
The ultra-high strength/modulus, extended chain polyethylene fiber (Spectra® fiber) composite has shown great potential as a lightweight armor material with its extraordinary capability of absorbing the kinetic energy of projectiles. But the relatively low melting point of this fiber (-145 o C) has caused concerns regarding the effect of temperature rise during the impact/penetration process on the performance as armor material. In this article, an analysis of temperature rise in projectile and the fiber composite during the impact/penetration process is described
