Recently, investigations have been conducted on the use of natural fibers as reinforcement in low-melting point thermoplastics
to improve mechanical properties of composites. However, due to some limitations of natural fibers, composite formulation
and processing parameters must be controlled to produce a product with improved properties. This study was conducted to investigate
the influence of flax fiber loading, use of compatibilizer and pretreatment on physical and mechanical properties of compression-molded
composite. In this study, untreated and treated (sodium hydroxide-treated and mild-bleached flax fibers) fibers at 15% and
30% of the total product mass were used in formulations. To investigate the effect of compatibilizer on product properties,
maleic anhydride grafted polypropylene (MAPP) was added at 5% by mass in the formulations. After extrusion of composites formulations,
they were formed using compression molding. Results indicated that using flax fiber in composites without pretreatment and
compatibilizer could result into products with inferior physical and mechanical properties; this could be compensated by the
use of a compatibilizer. However, the use of compatibilizer had some negative effects on some other physical properties like
color and melt flow index (MFI). 相似文献
