摘要

仿生皮肤材料是一种由高分子材料复合而成的,作为汽车碰撞安全性能实验假人皮肤肌肉的一种特殊功能材料.实验假人皮肤的反弹力和损伤因子影响汽车碰撞安全性能实验,影响汽车碰撞测试对人体的损伤程度判定的科学性和准确性.而仿生皮肤材料的力学性能主要受制备过程中混合基、填料的用量和硫化时间的不同等因素影响.针对汽车碰撞实验假人仿生皮肤材料的特殊性,为了制备综合性能优越的仿生皮肤,对仿生皮肤材料的制备与力学性能进行研究,研究不同混合基胶、固化剂、填料剂和后硫化时间对仿生皮肤材料力学性能的影响,通过对3种制备不同的仿生皮肤材料进行超声波测试和冲击测试分析,探讨具有最优力学性能仿生皮肤材料的合成途径.%Bionic skin material is a special kind of functional materials made of a polymer composited materials, which can used in the automobile collision test for safety performance of dummy skin and muscle. The resilient and injury factor of dummy skin will have some affection to the automobile collision test for safety performance, and it has also the impact for the car crash test to determine the scientific and the accuracy of damaging on the human body. But the mechanical properties of bionic skin materials are mainly determined by the mixed base, the amount of filled material and the curing time in the preparation process. For the special performance of bionic skin materials used in automotive crash tes, the mechanical properties and the preparation of the bionic skin materials are studied, and the impact of the different mixed base rubber, curing agent, filler agents and post-curing time on the mechanical properties of bionic skin materials are also studied. Finally, the synthetic pathway of bionic skin materials with optimal mechanical properties is approched, with the help of ultrasonic testing and impact testing for three different bionic skin materials.
