Fibreglass reinforced epoxy (FGRE) composite wastes particles reinforced polypropylene has been developed and its modelling has been performed. FGRE wastes were ground and treated with latex to reduce itching of fibreglass and then dried and reground to obtain the powdered particulates that were used as reinforcements for polypropylene. The reinforcements have been size-classified as 150, 200, 250 and 300 microns and the composites have been injection moulded. Heat release rate and other flame properties have been evaluated by Oxygen Bomb Calorimeter. Ignition time, flame propagation rate, combustion time, heat of combustion and heat release rate have been measured. Results indicate that ignition time, combustion time and heat of combustion increase with increase in the amounts of FGRE particulate reinforcements, but the flame propagation rate and heat release rate decrease. FGRE waste particles give outstanding ignition time with increasing reinforcement contents in the composites, and therefore use of FGRE waste as reinforcement material in place of cheese wood fibre in polyolefin would help reduce deforestation and add value to the economy. Models have been developed. 9 Refs.
