thermal, abrasion and dynamic-mechanical properties of sugar cane bagasse reinforced polyester resin biocomposites

Biodegradable composites (scb-pes) and a control sample were developed from polyester resin (pes) matrix and sugar cane bagasse (scb) fibre at different matrix- fibre compositions using the compression technique. the effects of fibre content (9–54 wt%) and fibre treatment on thermal and dynamic mechanical properties of polyester / sugar cane bagasse fibre biocomposites were evaluated via thermogravimetric analysis (tga) and dma (model: dma 242 e artemis) storage modulus (e1), loss modulus (e11), change in length of modulus (δl), tan delta (e11/ e1) and glass transition temperature (tg). the results showed that while the weight of the pure pes matrix showed a near complete disappearance between 400 –500 °c, the 9 % fw scb-pes composite lost nearly 50% of its weight, in the same temperature region. the results which show that scb-pes composites demonstrated acceptable thermal and abrasion properties portrays the effectiveness of scb as reinforcement for pes matrix and the potential of the eco-friendly composites in the fabrication of utility materials for sustainable development. the weight loss (wt%) by the composites after 6 months soil burying test ranged from 22.24 -85.34 %.
