Thermally resistant polymer composites reinforced with fibreglass

The aim of this paper was to obtain and characterize polymeric composites based on polyamide (PA) and polycarbonate (PC), reinforced with chemically activated surface fi breglass (FG), with advanced properties and temperature resistance. Polyamide was employed as the polymeric matrix, and the polycarbonate as disperse phase. As PA and PC are immiscible due to the polarity differences, a polyoxazoline compatibiliser was used. Afterwards, fibreglass was introduced in this composite. However, in order to obtain these properties, many variations of recipes had to be tested, with different concentrations of the components. The starting point was a mixture of 70% PA and 30% PC. The amount of compatibiliser varied up to 5%, and the FG amount, up to 30%. The characteristics of these polymeric composites with compatibiliser and simple and treated fibreglass were studied.
