Abstract Wood polymer composites (WPC) are gaining popularity and widespread usage due to an increased awareness of human population towards the importance environmental effects green eco-friendly materials. Mechanical properties WPC could be improved through graft copolymerization monomer onto wood fiber improve interfacial bonding. In this study, a comparison free radical using microwave-assi...

One of the key issues associated with using of composites in various applications is their tensile behavior. The tensile behavior of a composite material is strongly influenced by the properties of its constituents and their distribution. This paper focuses on gaining some insights into the tensile process of pure and hybrid woven composite reinforced with brittle and ductile yarns. For this pu...

One of the most common biological composites is wood material. This natural orthotropic like material is characterized by a high anisotropy determined by the special disposition of the microstructure elements. The anisotropy of wood can be described in various ways using the values of ultrasonic velocities of bulk waves (longitudinal and shear) observed on the velocity surface deduced from the ...

A commonly used natural cellulose fiber (flax) and a regenerated (Lyocell) were at 20 wt% to reinforce polylactide stereocomplex (sc-PLA) composites. Composites prepared by melt compounding fibers an equivalent proportion of PLLA/PDLA, followed injection molding. The structures properties these two kinds fiber/sc-PLA composites compared evaluated. results showed that the total crystallinity cry...

Coupling agents in wood fiber and polymer composites (WFPC) play a very important role in improving the compatibility and adhesion between polar wood fibers and non-polar polymeric matrices. In this paper, we review coupling agents, pretreatment, and mixing technology for wood fiber and polymer currenrly used in the manufacture of WFPC. So far, over forty coupling agents have been used in produ...

Wood-plastic composites represent a growing class of materials used by the residential construction industry and the furniture industry. For some applications in these industries, the fire performance of the material must be known, and in some cases improved. Lab-scale fire performance tests allow for comparisons between WPC formulations. At the Forest Products Laboratory (FPL) oxygen index tes...

in this research, old magazine (omg) recycled fiber and glass fiber (gf) were mixed at different levels of 10%, 20%, 30% and 40% (based on weight) with two levels of 50% and 60% polypropylene (pp) and then the produced composites evaluated compared to those from net polypropylene. on the basis of obtained results from normalization equations in different treatments done, two treatments has been...
