In this article, with the help of mathematical modeling curing rate, influence factors directly affecting processes an auto-filler prepared based on unsaturated polyester resin was studied: concentration accelerator, hardener, and temperature. When process, temperature concentrations were taken as initial (input) parameters, rate at various temperatures final (output) parameter.

Using the experimental determinations obtained on basis of compressive stress, some mechanical properties were studied for composite materials with matrix three types resin, epoxy, unsaturated polyester and hybrid based Dammar natural which was reinforced isophthalic resin granules NPG (Neopentyl Glycol) Chromat Kayan / Javari Payette type. The stress-strain diagrams, yield strength, strength m...

The aim of this study is to assess the environmental performance manufacturing process glass/polyester laminates as well estimate their fire behaviour and smoke release. Life Cycle Assessment was conducted according ISO14040/44 standard by using CML-IA 2000 Baseline Midpoint method. cone calorimeter a method ISO 5660. tests were performed under 25 kW/m2 heat flux 50 kW/m2. results showed that r...
