摘　　要：采用层状复合工艺,制备了超高分子量聚乙烯(UHMWPE)-聚氨酯泡沫(PUF)复合材料;设计了复合材料抗爆装置,对复合材料的抗爆性能进行了外场实验。以实验为基础,建立了复合材料抗爆数值模型,对复合材料的抗爆性能进行了数值模拟,对比分析了钢板和UHMWPE-PUF复合材料的抗爆效能。研究表明,将UHMWPE材料与PUF材料进行复合,可以充分发挥UHMWPE材料的高强、高模特点以及PUF材料较高的吸能特性,并且弥补了PUF材料强度低的缺陷,由此2种材料复合而成的UHMWPE-PUF复合材料的强度得到提高,且对爆炸冲击波的衰减性能也得到极大提高,在爆炸防护领域有着很好的应用前景。Ultra high molecular weight polyethylene （UHMWPE）- polyurethane foam （PUF） composite was synthesized by laminated composite technology. The anti-explosion unit of composite was designed and anti-explosion property was studied by out-field experiment. The anti-explosion numerical model was established on the base of experiment and anti-explosion efficiency was analyzed. The results show that compounding UHMWPE and PUF can give full play to the high strength and high modulus feature of UHMWPE material and the energy absorbing property of polyurethane foam material, the low strength imperfection of polyurethane foam plastics was remedied. UHMWPE-PUF composites can not only improve the strength but also shock wave attenuation properties, which have a good prospect in the field of anti-explosion.
