Abstract
The aim of this paper is to study the effect of magnesium hydroxide burning rate, mechanical properties and surface morphology analysis of Arenga pinnata fibre hybrid with polyester yarn (APF/PET) reinforced epoxy composite with the addition of magnesium hydroxide as flame retardant. The composites were prepared with different amount of fibres (i.e. 0%, 20%, 35% and 50% by weight percent) and two constant material of 5% which are the magnesium hydroxide and the polyester yarn with epoxy resin as the matrix. With the incorporation of the flame retardant the horizontal burning rate of APF/PET reinforced epoxy decreased with the amount of 35% APF. The fibre loading increased to 50% as the mechanical properties of the hybrid composite decreased which due to the lack of interfacial bonding between the fibres and matrix. Surface morphology studies through scanning electron microscopy showed the similar distribution of Arenga pinnata fibres and matrix with less adhesion which reduce the mechanical properties of the hybrid composites.
