Abstract

Epoxy has a wide range of applications in many sectors, but it still has deficiency in fire retardancy. Therefore, it is combined with fire retardant additives. Fire retardant additive commonly contains halogen compounds that causes environmental and health problems. Therefore Al (OH)3 additive is used to improve the fire retardancy properties of composite through decomposition that produced water vapour and formation of oxide layer on its surface. In this research, synthesis of fire retardant composite has been conducted by varying filler carbon black and silica (1%, 2.5%, 5%, 7.5%, 10%wt) with composition of Al (OH)3 50%wt and epoxy 50%wt. Fire retardancy of composite was observed by UL-94V standard, while thermal degradation behaviour of composite was analyzed by thermal gravimetric analysis and differential scanning calorimetry. Whereas, mechanical properties was studied based on its tensile strength and hardness. It was found that the best concentration for carbon black and silica is 1%wt and 2.5%wt respectively. The addition of carbon black 1%wt and silica 2.5%wt could improve the flame retardancy and gives V-0 flammability rating. Besides that, the addition of carbon black 1%wt is able to increase the thermal stability of composite by reducing mass loss rate until 10.75%/minute and total mass loss until 53.76%. While adding silica 2.5%wt could also enhance its thermal stability by decreasing mass loss rate until 9.32%/minute and total mass loss until 51.06%. Furthermore, the addition of carbon black and silica could decrease its tensile strength and hardness. The addition of carbon black 1%wt yields composite with 6.59 MPa for tensile strength and 65.8 shore D for hardness. Whereas the addition of of silica 2.5%wt produces composite with the tensile strength up to 9.89MPa and hardness up to71.2 shore D.
