Organified Attapulgites (AT) were grafted with 3-(trimethoxysilyl) propyl methacrylate ( KH570 ) on the surface of AT particles. Then, the modified AT (AT-g-KH570) and untreated AT particles were compounded with polypropylene (PP) to prepare PP/AT-g-KH570 and PP/AT composites respectively. The morphology, chemical structure and mechanical properties of the composites were also investigated with scanning electron microscopy (SEM), Fourier-transform infrared spectra (FTIR) and mechanical testing. The FTIR results showed that the KH570 is grafted on the AT particles. The tensile strength and izod impact strength of PP/AT-g-KH570 composites were improved obviously than those of PP/AT composites. The izod impact strength of PP/AT-g-KH570 composites show the maximum and was enhanced 50 % at 1 wt% loading, which contributed to homogeneous dispersion of particles and enhanced the interfacial interaction between modified AT particles and PP matrix.

Waste Expanded polypropylene (EPP) was utilized as recycled matrix for kenaf fiber-reinforced polypropylene (PP) composites produced using chopped kenaf fibers and crushed EPP waste. The flexural properties, impact strength, and heat deflection temperature (HDT) of kenaf fiber/PP composites were highly enhanced by using waste EPP, compared to those by using virgin PP. The flexural modulus and strength of the composites with waste EPP were 98% and 55% higher than those with virgin PP at the same kenaf contents, respectively. The Izod impact strength and HDT were 31% and 12% higher with waste EPP than with virgin PP, respectively. The present study indicates that waste EPP would be feasible as recycled matrix for replacing conventional PP matrix in natural fiber composites.
