Abstract

The response of solids (TOSP-1 polymethylmethacrylate, D1 aluminum alloy) to multiple collisions with 1-mm ice granules with an average velocity of about 100 m/s is experimentally studied at low climatic temperatures (–40°C). When ice granules collide with a target, 100-μm fragmentation particles are found to form and cause the destruction of the target surface.

冰粒助熔剂破坏聚甲基丙烯酸甲酯和铝合金的实验研究

摘要

在低气候温度 (–40°C) 下，通过实验研究了固体（TOSP-1 聚甲基丙烯酸甲酯，D1 铝合金）与平均速度约为 100 m/s 的 1 mm 冰粒的多次碰撞的响应。当冰粒与目标碰撞时，会形成 100-μm 的碎裂颗粒并导致目标表面的破坏。
