Performance of Rubberwood Fiber–Thermoplastic Natural Rubber Composites

Abstract

Rubberwood fiber-thermoplastic natural rubber (RWF -TPNR) composites were prepared and evaluated in this study. The RWFs were supplied in the form of thermomechanical pulp (TMP) from the Hume Fiberbord Company in Malaysia. The fibers were screened to 0.5 -1 mm sizes and blended with TPNR and maleic anhydride -grafted polypropylene (MAPP) as a compatibilizer in the internal mixer of Brabender Plasticorder machine. The mechanical, thermal properties and morphology of the composites were investigated by tensile, impact, flexural, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and scanning electron microscope (SEM). The results showed that the tensile strength and Young's modulus increased, while tensile strain and impact strength decreased with increasing of fiber loading. Thermogravimetric analysis showed an increasing degradation temperature of the samples with RWF. On the other hand, SEM micrographs

Green composites from kapok husk and recycled polypropylene

“…Usually, unmodified natural filler has poor dispersion, wettability, and adhesion with thermoplastic material. In general, the good performance composites can be achieved by filler modification via alkaline treatment, 16 –18 esterification, 1,3,9,13,19 –21 silane treatment, 2,22,23 use of maleated polymer, 10,24 –27 and other chemical. 4,11 Besides, fatty acid and its derivative can be also used as green coupling agent in natural filler treatment as it acts asa coupling effect on the natural filler-based composites.…”

Ductile–brittle transition temperature of polylactic acid-based biocomposite

“…Apart from its lower cost, KF is also low in density, nonabrasive, and biodegradable and has fairly good mechanical properties. [10][11][12] KF, which is derived from renewable resources, is suitable for use in automotive applications, building, appliance, and so on.…”

The use of waste rubber in natural rubber in the presence of maleic anhydride-grafted natural rubber (MA-g-NR): study on curing, rheology, morphology, and properties of the blend

“…Grafting of MA onto non-polar polymers increases the hydrophilicity of the polymer surface. Therefore, the maleated polymer can be used as a main component in a reactive blending process [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. The grafting of MA onto NR has been commonly done in the molten state by using shearing action in the presence or absence of peroxide.…”
