Wood Fiber Reinforced Polyethylene and . - CiteSeerX

ABSTRACT: Wood plastic composite with high modulus and impact strength were manufactured by combining polyethylene (PE) or polypropylene (PP) with wood fiber (WF) using twin-screw extruder techniques. The advantage of using low melt viscosity polymer matrices is that it enhances the modulus and reduces the.

Reinforcing effects of Kevlar fiber on the mechanical properties of .

Kevlar fibers (KFs) were used as a reinforcement for wood-flour/high-density-polyethylene composites (WF/HDPE) to improve the mechanical properties of the resulting composites. Addition of a small amount (2–3%) of KF caused an improvement in the tensile, flexural, and impact properties of WF/HDPE. Surface grafting of.

Maleated wood-fiber/high-density-polyethylene composites .

2 Apr 2012 . Chemical coupling of maleated polyethylene (MAPE) copolymers at the interface in wood-fiber/high-density-polyethylene (HDPE) composites was investigated in this study. FTIR and ESCA analyses presented the evidence of a chemical bridge between the wood fiber and polymeric matrix through.

The effect of micron sized wood fibers in wood plastic composites

The popularity and demand for wood plastic composites (WPC) has focused research on fiber properties associated with performance. In this study, maple wood fibers (WF) were ball milled and classified into discrete size fractions. Fiber analyses showed only three distinct WF size classes (80-100, 100-200 and <200 mesh).

The Effect of the Chemical Modification of Wood Fibre Using . - USM

Abstract: The effect of the chemical modification of wood fibre (WF) using salicylic acid/ethanol on the tensile properties, water absorption, thermal degradation and morphology of recycled high density polyethylene/WF (rHDPE/WF) composites was studied. Both of the composites: rHDPE/WF and rHDPE/WFM (modified with.

Preparation and Properties of Wood Plastic Composites Made of .

21 Dec 2017 . The tensile strength of the composites containing PE-g-MA was superior to those of the composites without compatibilizing agent. As expected, the flexural of the composites increased with the wood content. Low internal bond strength was observed for the panels with different fiber loading and.

Wood-fiber/high-density-polyethylene composites - Wiley Online .

ABSTRACT: The compounding process directly influ- enced the compounding quality of wood–polymer blends and finally affected the interfacial bonding strength and flexural modulus of the resultant composites. With 50 wt % wood fiber, the optimum compounding parameters for the wood-fiber/high-density-polyethylene.

PLASMA-MODIFIED WOOD FIBERS AS FILLERS IN POLYMERIC .

Wood fibers were used as fillers to obtain composites with polyethylene and rubber.
