This study examined the effect coextruding a clear HDPE cap layer onto HDPE/wood-flour composites has on the discoloration of coextruded composites exposed to accelerated UV tests. Chroma meter, XPS, SEM, and UV vis measurements accounted for the analysis of discoloration and degree of oxidation of both uncapped (control) and coextruded composites before and after UV exposures. Two separate dis...

Thermogravimetric analysis was carried out to investigate the thermal degradation of High Density Poly Ethylene (HDPE) short fibers reinforced epoxy composites. Three composites with 5, 10 and 15 % by weight of HDPE short fiber composition were prepared using epoxy as matrix material. The HDPE short fiber used as reinforcing material into the resin helps in retarding the thermal degradation of ...

Wood–plastic composites (WPCs) increase the range of applications materials by creating new material solutions. As part this research, PLA (polylactic acid)- and HDPE (high-density polyethylene)-based were manufactured. Softwood sawdust or conifer bark with different sizes (large small) used as filler. In selected cases, addition 3% additives, such calcium oxide in case polyethylene-graft-malei...

Abstract This article presents the potential use of tree waste materials such as leaves (L), branches (B) and trunks (T) Azadirachta excelsa (Sentang) in production wood polymer composite (WPC). The WPC was fabricated from high-density polyethylene (HDPE) bonding matrix, maleic anhydride (MA) coupling agent, Sentang particles (L, B T) filler, prepared using twin-screw extruder followed by injec...

When increasing the wood fiber (WF) content in extruded wood fiber/plastic composites (WPC) foams, a good balance between reducing the cost and obtaining good cell morphology should be maintained. This study examines the relationship between WF content and the foam morphology in WPC foams. The role of WF as cell nucleating agent at low concentrations (10 wt.%) was observed, as WPC foam with 10 ...

This study investigated the effect of board type (unmodified vs. MAPE modified) on the surface quality and thickness swelling-water absorption properties of recycled high density polyethylene (HDPE) based wood plastic composites. Additionally, two commercially available coatings (cellulosic coating and polyurethane lacquer coating) were also applied to composite surfaces and their adhesion stre...

The objective of this study was to investigate the utilization waste tea wood fibers (WTWF) and effect maleic anhydride treated polyethylene (MAPE) in thermoplastic composites. For purpose, HDPE as matrix, WTWF lignocellulosic filler MAPE coupling agent were used. Six different composites produced by injection molding method; 0-15-30% ratio, with without MAPE. physical, mechanical, thermal morp...

Composites based on recycled high density polyethylene (RHDPE) and natural fibers were made through melt blending and compression molding. The effects of the fibers (wood and bagasse) and coupling agent type/concentration on the composite properties were studied. The use of maleated polyethylene (MAPE), carboxylated polyethylene (CAPE), and titanium-derived mixture (TDM) improved the compatibil...

Composites based on high density polyethylene (HDPE), pine flour, and organic clay were made by melt compounding and then injection molding. The influence of clay on crystallization behavior, mechanical properties, water absorption, and thermal stability of HDPE/pine composites were investigated. The HDPE/pine composites containing exfoliated clay were made by a two-step melt compounding proced...

Now-a-days everyone is aware of the disadvantage Plastic and its various products. Around 300-400 tonnes plastic waste generated every year. This also results in man environmental pollution as well human health issues. But, this doesn’t mean that we completely don’t need plastic. It has much application field composites which trending a good alternative wood. Composite materials have significan...
