The effects of alkaline copper quaternary (ACQ) and zinc borate (ZB) on the resistance of corn stalk fiber (CSF)-reinforced high-density polyethylene (HDPE) composites to biodegradation were examined. Both biocides could inhibit termites, mold fungi, and wood-decay fungi, even at high CSF formulations (i.e., 60%). Additionally, ACQ enhanced the resistance of the composite materials to certain b...

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...

To modify water absorption properties of bamboo fiber (BF) and high density polyethylene (HDPE) composites, heat treatment of BFs was performed prior to compounding them with HDPE to form the composites. The moisture sorption property of the composites was measured and their diffusion coefficients (Dm) were evaluated using a one-dimensional diffusion model. Moisture diffusion coefficient values...

During the last few years, natural fibers have received much more attention than ever before from the research community all over the world. These natural fibers offer a number of advantages over traditional synthetic fibers. The present study aims to determine the mechanical properties namely, Tensile strength (TS), Flexural strength (FS), and Impact strength (IS) of green coconut fiber reinfo...

in this research, the effect of wood species and particle size on mechanicalproperties of wood plastic composites (wpc) made of fir (abies alba) and beech(fagus orientalis l.) sawdust and high density polyethylene (hdpe) wereinvestigated. wood plastic composite (wpc) were made with 30% hdpe in abatch process at 185˚c, at two particle sizes of 40 mesh and 80 mesh. maleicanhydride polypropylene (...

the influence of flour content and immersion time in water on the creep behavior of composites made from high density polyethylene (hdpe) waste and mdf (medium density fiberboard) flour was investigated. mixing was carried out by a twin screw extruder and the sample was manufactured by flat hot press. firstly, the modulus of elasticity and bending strength of various mdf flour-polyethylene comp...

Selective laser sintering (SLS) has been investigated for the production of bioactive implants and tissue scaffolds using composites of high-density polyethylene (HDPE) reinforced with hydroxyapatite (HA) with the aim of achieving the rapid manufacturing of customized implants. Single-layer and multilayer block specimens made of HA-HDPE composites with 30 and 40 vol % HA were sintered successfu...

The new applications for carbon nanotubes (CNTs) in various fields and consequently their greater production volume have increased their potential release to the environment. Landfills are one of the major locations where carbon nanotubes are expected to be disposed and it is important to ensure that they can limit the release of CNTs. Diffusion of multiwall carbon nanotubes (MWCNTs) dispersed ...
