Abstract

compósito com resistência balística, e método para formar compósito com resistência balística a presente divulgação se refere a um compósito com resistência balística 20, incluindo um ligante bimodal, o compósito pode ser moldado de uma forma em que ele seja exposto a baixa pressão por um curto espaço de tempo e numa temperatura controlada. mais particularmente, o ligante bimodal do compósito 20 permite que o compósito seja formado com um laminador de leito plano, por exemplo, que pode ser menos custoso do que outros métodos de processamento, tais como prensa de correia de aço.
