This work is concerned with the evaluation of the effect of manufacturing temperature on mechanical properties of composites. Composites were fabricated using Bamboo fibre/polyester, and Bamboo fibre with varying fibre manufacturing temperature in compression mould method. Bamboo fibre reinforced polyester composites were fabricated with varying temperature of (140, 160, 180 °C). The results showed that Flexural strength of the composite increased with increasing temperature up to 180°C for Bamboo fibre polyester composite. Flexural strengths of Bamboo fibre /polyester composites were found to be higher than those of room temperature process.
