Abstract:

In order to select the best geometry of the resin flakes to improve stab resistance, four kinds of resin films (square, equilateral triangles, hexagons and circles) with the same area are drawn out by the CAD, and then void width and void area are theoretically calculated and analyzed.The narrower the void width and the smaller the void area, the harder the tool is to pass through and this shape of resin flakes has a better stab-resistant ability. The results show that for square, equilateral triangles, hexagons and circles of closely tangency permutation, the square, equilateral triangles, and circles make straight lines between the flakes, and the cutting tool is easy to pass through the linear procession to harm human body. For polygon and circular resin flakes, when the void fraction is constant and the resin flake area is the same, the width of the gap between the regular hexagonal resin flakes is narrowest and the void area between every two hexagonal resin flakes is smallest. In summary, hexagonal resin flake is conducive to improve the stab resistance of materials.
