Abstract

processo para moldar uma resina de termocura, especialmente do tipo resina epóxi, no qual um primeiro molde é preenchido com a resina, enquanto varia a temperatura da resina de acordo com um primeiro programa de temperatura, sem exceder a tg da resina. após preencher o primeiro molde, a resina é pressurizada enquanto varia a temperatura da resina de acordo com um segundo programa de temperatura, sem exceder a tg, e uma queda na pressão exercida pela resina no molde é detectada localizando o instante t1 onde esta pressão tem uma mudança repentina de diminuição. um segundo molde é preenchido com a resina de termocura enquanto segue o primeiro programa de temperatura. após preencher o segundo molde, a resina é pressurizada seguindo o segundo programa de temperatura até um instante t2 próximo a t1. começando de t2, a temperatura da resina é aumentada excedendo a tg.
