Polyurethane Composites

Chicken feather particles reinforced rubber seed oil based polyurethane composites were produced and the physico-mechanical and microstructural analyses were studied. Casting method was used to produce the composites with varied weights of Chicken feather particles from 5 to 25wt% in steps of 5 wt%. The composites produced were analyzed for hardness, impact strength, tensile strength, density and water absorption properties according to ASTM standards. The density and impact strength were observed to decrease with increase in percentage weight of the chicken feather particles and this was attributed to the fact that the feathers have lower density than RSO-Polyurethane. Tensile strength and hardness of the composites were found to decrease at the intial stage (0 to 10 wt%) and later started to increase with percentage increase(15 to 25 wt%) of reinforment added. The microstructure reveals that there was a reasonable uniform distribution and bonding of chicken feather particles in the RSO-Polyurethane matrix.

Polyurethane samples were prepared from rubber seed oil monoglyceride (made by reacting rubber oil with glycerol) and diiosocyanates (hexanethylene and toluene diiosocyanates). Polyurethane composites were made by compression moulding using biofibres; sisal, jute and banana; in random and unidirectional orientations at different fibre lengths and loadings, as reinforcing elements. The composites were characterized in terms of tensile and flexural strengths and moduli, thermal stability and morphology of fractured surface. The values of the measured mechanical properties (tensile and flexural) of the composites were about 3-fold higher than the properties of the unreinforced polyurethane samples, suggesting good reinforcement by the biofibres. The absence of fibre-pull-out on the scanning electron micrographs of the fractured surface provides evidence in support of good adhesion between the biofibres and the polyurethane matrix. The thermal stability of the composites was lower than for the fibre but higher than for the unreinforced polyurethane.
