Effect of fiber attrition, particle characteristics and interfacial adhesion on the properties of PP/sugarcane bagasse fiber composites

PP/sugarcane bagasse fiber composites were prepared by injection molding from two fractions of fibers with different particle characteristics. The mechanical properties the characterized tensile and impact measurements, while local deformation processes acoustic emission testing microscopy. determination dimensions after processing showed that considerable attrition takes place during melt in both length diameter fibers. Interfacial adhesion can be improved considerably coupling. strength was estimated quantitatively ten times stronger (1600 mJ/m2) presence coupling agent than without it (140 leading to larger composite former case. Local also change adhesion, debonding dominates agent, fracture at good adhesion. Fiber consumes energy leads an increase resistance. size must reduced order achieve better properties, but application cannot avoided even
