摘要

无机填料的加入，能够较大程度上增强聚氨酯的性能，从而使以聚氨酯为芯层的复合结构性能得到提升。为得到具有更好抗侵彻能力的SPS复合板，利用原位聚合法得到氧化石墨烯增强聚氨酯弹性体并对其进行单轴拉压测试，在此基础上加入陶瓷球作为新的增强相，以Q235钢作为面板制备了芯层为石墨烯增强聚氨酯以及石墨烯/陶瓷球增强聚氨酯的SPS复合结构，通过钢球弹的侵彻实验并运用LS-DYNA数值仿真得到两种复合板的弹道极限速度，分析其吸能特性及损伤机理。结果表明：当石墨烯质量分数为0.4wt%时石墨烯增强聚氨酯的压缩模量较纯聚氨酯提高了32.4%，拉伸强度提高了42.6%。在加入陶瓷球后复合板的弹道极限速度提高了20.8%，陶瓷球的碎裂和偏移中断了径向应力的传播，子弹尺寸以外的陶瓷球较为完整。

Abstract

The addition of inorganic filler can greatly enhance the performance of polyurethane, so that the performance of the composite structure with polyurethane as the core layer can be improved. In order to obtain SPS composite plates with better penetration resistance, graphene oxide reinforced polyurethane elastomers were obtained by in-situ polymerization and tested under uniaxial tension and compression. On this basis, ceramic balls were added as a new reinforcing phase, and SPS composite structures with graphene reinforced polyurethane and graphene / ceramic balls reinforced polyurethane as the core layer were prepared with Q235 steel as the panel, Through the penetration experiment of steel ball projectile and LS-DYNA numerical simulation, the ballistic limit velocities of the two composite plates are obtained, and their energy absorption characteristics and damage mechanism are analyzed. The results show that when the mass fraction of graphene is 0.4wt%, the compressive modulus of graphene reinforced polyurethane is increased by 32.4% and the tensile strength is increased by 42.6% compared with pure polyurethane. After adding ceramic balls, the ballistic limit velocity of the composite plate increased by 20.8%. The fragmentation and offset of ceramic balls interrupted the propagation of radial stress, and the ceramic balls beyond the size of bullets were relatively complete.
