Glass fiber is the most popular reinforcement material for improving mechanical properties of composites. While tranforming glass fiber filaments to chopped ones, too many waste glass fiber exists. This paper deals with waste glass fiber usage in composites with melamin matris. Tensile strength behaviour, bending resistance, specific gravity and impact resistance of samples were analysed. Results showed that homogenity of composite mixture was very important in characteristics of end products. Increase in specific gravity was negligible because reinforcing material, namely waste glass fiber, was less sensitive than melamine thermoset to hot pressing method. Thereto, waste glass fiber reinforcement enhanced the tensile resistance and impact strength up to 30% and 20%, respectively. Addition of glass fiber waste lead to a sharp decrease in bending resistance, approximately 50%.
