为了探究2D、3D织物结构对剪切增稠液体(STF)/超高分子量聚乙烯(UHMWPE)复合材料高速冲击性能的影响,分别使用2D UHMWPE织物和3D UHMWPE织物与STF复合,制备STF/UHMWPE复合材料,再分别与UD布结合制备3组靶样。A组为纯UD布靶样;B组为UD布STF/UHMWPE(2D)复合材料靶样;C组为UD布STF/UHMWPE(3D)复合材料靶样,并对3组靶样进行高速冲击实验。实验结果表明:STF/UHMWPE(2D)复合材料在高速冲击实验中性能更好,复合材料在径向上吸收能量的能力强于纵向。
In order to investigate the effect of 2D and 3D fabric structures on the high-speed impact properties of shear thickening liquid (STF) / ultra-high molecular weight polyethylene (UHMWPE) composites, 2D UHMWPE fabric and 3D UHMWPE fabric were respectively composited with STF to prepare STF / UHMWPE Composite materials, and then with the UD fabric preparation of three groups of target. Group A was a pure UD cloth target; Group B was a UD cloth STF / UHMWPE (2D) composite target; Group C was a UD cloth STF / UHMWPE (3D) composite target, and three groups of targets were subjected to high-speed impact experiment. The experimental results show that the composites of STF / UHMWPE (2D) have better performance in high-speed impact experiments and the composites have stronger ability to absorb energy in the radial direction than in the longitudinal direction.
