TGF treated with 10% LENR

Reinforcement of Thermoplastics Natural Rubber Composite with Liquid Epoxidised Natural Rubber Treated Torch Ginger Fiber

Nur Khairul Nabila Kamaruddin, Ibrahim Abdullah, Ishak Ahmad


The high interests in natural fiber reinforced thermoplastic natural rubber composites are related to the issues of biodegradability, environmental friendly and renewable resources. Effects of coating Torch Ginger fiber (TGF) with liquid epoxidised natural rubber (LENR) as a compatibiliser between TGF and natural rubber and linear low polyethylene (NR/LLDPE) composite were investigated. LENR coated TGF reinforced thermoplastic NR/LLDPE composites were prepared by incorporation of 10% loading of TGF with different degree of LENR coating. To improve the adhesion of LENR coated to TGF pre-treatment of TGF powder using 4% NaOH was done in order to expose more hydroxyl groups on TGF surface before coating with LENR. The scanning electron microscope (SEM)micrograph of TGF surface showed the LENR coated on the pre-treated TGF surface was homogeneous. The mechanical properties of TGF reinforced thermoplastics were found to increase when TGF was treated with 4% NaOH followed by 5% LENR coating. Effects of TGF treatment on the rheological behavior of composites showed an increase in the adhesion of LENR treated TGF. SEM micrograph of the tensile fractured surface showed good interfacial interaction between NR/LLDPE matrix and 5% LENR coated TGF compared to untreated and NaOH treated TGF
