A composite with a polyester matrix reinforced with chemically modified shells of castor seed (Ricinus communis) was produced. The effect of the shell (filler) on the mechanical properties of the composite was experimentally quantified. A preliminary study was earlier carried out the shell in terms of their chemical constituents, functional group and mechanical strength. The shell was ground and chemically treated to enhance good bonding and adhesion to the matrix. Composites were fabricated using a hand lay-up or contact mould method for different percentage compositions of the filler. Tests, with respect to the mechanical properties (i.e., tensile, flexural and creep response) were carried out. The result obtained was compared with the unreinforced polyester plate. It was observed that the inclusion of the filler (shell) added strength to the composite. Scanning Electron Microscopy (SEM) was taken on the composite samples to study the morphology of the composites.
