Abstract
As improvement of industry and society, some potential crisis happened in working and living environment is taken into account by human people. Meanwhile, different kinds of protective appliances develop rapidly, and composite boards with cushion and puncture-resistance property are required consequently. This study aims to develop a cushion/puncture-resistance PU foam protective composites. This paper used Polyol and Isocyanate to prepare porous PU foam composite via foaming and curing process. By changing foam density and addition amount, cushion and puncture-resistance property were tested and then evaluated to seek for PU foam composite with cushion and puncture-resistance property. Result shows that, when density was 80 kg/m3, PU foaming composite board had the optimum resilience rate of 44 %, lowest impact remaining load of 638 N and best puncture-resistance force of 138.3 N.
