The propenies of the interphase in wood-polymer composites ~ important determinaou of the propenies of the final composite. This study used inverse ps chromatOll'Bphy (IGC) to measure interpbasal propenies of composites of polystyrene and two types of wood fiber fillers and an inOllaDic substrate (CW) with varying amounts of surface cove,. of polystyrene. Glass transition temperatures, thennody...

In this study, a new method of forming conductive large area metal/polymer composites called top plate friction stir processing was performed using thin aluminum and HDPE sheet. To form the composite, rotary tool uses to heat lapped into HDPE. This differs from other forms polymers because base material does not need modification prior processing, increasing total manufacturing efficiency. Upon...

Though silane chemistry has been used to crosslink unfilled polyethylene for many years, such crosslinking has only been recently applied to wood plastic composites to improve properties such as creep resistance. However, the presence of wood significantly changes the silane chemistry and a greater understanding is necessary for optimal processing and performance. We investigated three differen...

A new type of wood plastic composite, Eucalyptus/PES(Polyethersulfone) blend, was developed. It was designed to be used in LS (Laser Sintering) with reduced energy usage with cost savings. The preparation of Eucalyptus/PES blend and part sintering were under fixed processing conditions and parameters. Through mechanical testing, it was discovered that the strength of prototypes is low due to th...

Abstract This paper aimed to produce a bio-based filament, suitable for 3D printing (fused deposition modeling), made of surface modified cellulose fiber and high density polyethylene. The fibers (CF) were first transformed into CF-based macroinitiator through an esterification reaction with the 2-bromoisobutyric acid. We finally studied ability this initiate single electron transfer-living rad...

Micron-sized particles, prepared from loblolly pine (Pinus taeda L.) wood and bark, were evaluated for use in wood-plastic composites (WPCs). Particles were also prepared from hard (periderm) and soft (obliterated phloem) components in the bark and compared to whole wood (without bark) filler commonly used by the WPC industry. All bark fillers had different thermal degradation profiles and high...

This work aims to describe the coffee silverskin effect as a lignocellulosic waste filler for high-density polyethylene (HDPE) composites development. The main task was determine various modification effects resulting from complex chemical composition of containing compounds with potential antioxidative properties, including caffeine, polyphenols, tannins, or melanoidins. processing, thermal, p...

The objective of this paper is to present a method for the design of solid wood panels with cross layers. The stress distribution in and the deformation behaviour of solid wood panels were analysed using the composite theory. The shear influence in solid wood panels was determined using the shear analogy method. A strength class system is proposed for the design of solid wood panels with cross ...

This study explains the influence of secondary filler on the dispersion of carbon nanotube (CNT) reinforced high density polyethylene (HDPE) nanocomposites (CNT/HDPE). In order to understand the mixed-fillers system, Montmorillonite (MMT) was added to CNT/HDPE nanocomposites. It was followed by investigating their effect on the thermal, mechanical and morphological properties of the aforesaid n...
