The mechanical property analysis of K2Ti6O13 whisker reinforced keratin composites
Regenerated wool keratin materials have a limit on the achievable properties due to the low modulus and strength. Modification of this material with whiskers would allow for significant increases in the modulus and strength contributions of the matrix to the overall composite properties. The final properties of composite materials are highly dependent on the surface treatment and orientation of the reinforcements in the matrix, which in turn are related to the processing conditions. In the present paper, wool keratin composites reinforced by potassium hexatitanate (K2Ti6O13) whiskers were successfully prepared by sonication and molding. Their mechanical properties were tested, and scanning electron microscope (SEM) micrographs of fracture surfaces performed on the coupled composites clearly demonstrated better interfacial adhesion between fibre and matrix. Results showed that the whisker was benefit for improving the mechanical properties of composite materials after being orientated arranged and surface-treated by coupling agents properly.
