ABSTRACT: Biodegradable polymeric composites were time of PBS/KF composite in isothermal crystallization at fabricated from poly(butylene succinate) (PBS) and kenaf 96 and 100C were reduced to 10.8% and 14.3% of that of fiber (KF) by melt mixing technique. The mechanical and the neat PBS, respectively. SEM analysis indicates that the dynamic mechanical properties, morphology and crystalli- adhesion between PBS and KF needs further improve- zation behavior were investigated for PBS/KF composites ment. These results signify that KF is efficient in improv- with different KF contents (0, 10, 20, and 30 wt %).

Hence, this study provides a rate of PBS in the composites were all efficiently enhanced. good option for preparing economical biodegradable com- C V With the incorporation of 30% KF, the tensile modulus posite.
