Biocomposites have received a great deal of attention in academic research and industry because they are environmentally friendly and produce less carbon footprint, especially with the use of natural fibers. Nevertheless, compatibility issues require complexity to overcome the field of composite materials. Biocomposites based from poly(lactic acid) (PLA), natural rubber (NR) and kenaf were prepared by melt blending in an internal mixer. PLA/NR composition was fixed at 90/10 (wt/wt), while kenaf loading varied from 0 to 20 phr. The aim of this work was to study the effect of epoxidized natural rubber (ENR) and poly(methyl methacrylate) (PMMA) addition as co-compatibilizers in the biocomposites. Rheological behavior during mixing showed higher processing torque and stabilization torque after compatibilization. The mechanical properties deteriorated with increasing kenaf loading in biocomposites …
