Abstract

The development of bio-based polymer composite materials not only promotes a better environment but also assists to compensate for the gap between demand and supply of non- renewable materials. In the current research work, an attempt was made by fabricating cellulose reinforced polymer bio-composites in a step towards the development of sustainable and safe materials. Cellulose is extracted from the kenaf fibre using water pre hydrolysis synthesis. Bio composite materials are fabricated utilizing cellulose as reinforcement and isophthalic polyester as matrix phase. Mechanical (tensile and flexural) properties of the composite materials are studied as a function of cellulose loading. Tensile strength of the composite materials exhibited an increase (up to 10% cellulose) and decrease (from 15% cellulose) pattern with the respective percentage of reinforcement. Composite with 10% cellulose reported an almost 25% increase in tensile strength compared to neat resin. The fractured surfaces of composite materials were analysed by scanning with an electronic microscope. The fractured surface of 15% cellulose composite featured voids and non-uniform distribution of reinforcement. From morphological observations, the drop in strength in 15% cellulose composite materials can be attributed to the presence of voids and agglomeration of reinforcement.
