Abstract

The dynamic mechanical analysis of sugarcane bagasse/glass fibre hybrid reinforced epoxy composite was investigated and compared with all glass reinforced counterpart. Bagasse fibre mats were produced and non-woven glass fibre mats obtained locally were used to produce the composites laminates at 45 % volume fraction at different layering arrangement using the compression moulding technique. The storage modulus (E'), loss modulus (E") and the mechanical damping factor (tan δ) of the composite were analysed at 1 Hz over heating temperature of between 33 to 200 ºC at 2 ºC/min heating rate. Results showed that the hybridization reduced the storage modulus and the damping factor irrespective of layering sequence. Also, hybridization shifted the glass temperature (Tg) slightly to a higher temperature, and glass reinforced composite had the highest storage modulus value of 8GPa whereas all bagasse reinforced composite exhibited the highest damping factor of 4.74 × 10-1.
