This research work aims to fabricate bamboo fabric reinforced polyester composites (BFRPCs) and investigate the mechanical and degradation properties of BFRPCs. Composite samples were prepared using hand lay-up technique. Bamboo fabric was used as reinforcement material, unsaturated polyester resin (UPR) was used as matrix and Methyl ethyl ketone peroxide (MEKP) was used as initiator which was employed as 0.5, 1, 2, 3 and 4% concentration. The mechanical properties of the BFRPC samples such as tensile strength (TS), tensile modulus (TM), bending strength (BS), bending modulus (BM) and impact strength (IS) were conducted. The degradation behaviors of the composites in soil burial, immersed in alkaline water and saline water were also evaluated. The BFRPC sample with 2 (%) MEKP concentration showed better tensile properties with TS and TM values of 39 MPa and 744 MPa respectively. For the 1 (%) MEKP concentration, the maximum values of BS, BM and IS were found to be 62.8 MPa, 1229 MPa and 25.7 kJ/m2 respectively. In the case of soil burial degradation the BFRPC sample with 1 (%) MEKP concentration shows better performance against loss of TS. No significant effect was found on the alkaline and saline water degradation properties of BFPRC for the variation of MEKP concentration. With the increase of all types of degradation time, decrease the tensile strength of all BFRPC samples.
