Rheological Behavior of Hdpe-wood Flour Composites with Different Wood Contents
Rheological behavior of high-density polyethylene (HDPE)-wood flour composites with different wood contents was examined using steady shear sweep, oscillatory frequency sweep, creep test, and stress relaxation test. The samples were prepared using a melt compounding method in a twin-screw extruder. The results showed that the yield stress did not appear for the composites prepared under the pro...
متن کاملSurface chemistry changes of weathered HDPE/wood-flour composites studied by XPS and FTIR spectroscopy
The use of wood-derived fillers by the thermoplastic industry has been growing, fueled in part by the use of wood-fiber– thermoplastic composites by the construction industry. As a result, the durability of wood-fiber–thermoplastic composites after ultraviolet exposure has become a concern. Samples of 100% high-density polyethylene (HDPE) and HDPE filled with 50% woodflour (WF) were weathered i...
متن کاملNon-isothermal Crystallization Kinetics of Kevlar Fiber-reinforced Wood Flour/hdpe Composites
Non-isothermal crystallization of neat high density polyethylene (HDPE), wood flour (WF)/HDPE composite (WPC), virgin Kevlar fiber (KF) reinforced WPC (KFWPC), and grafted Kevlar fiber (GKF) reinforced WPC (GKFWPC) was investigated by means of differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD). Several theoretical models were applied to describe the process of nonis...
متن کاملeffect of nanoclay particles on the physical properties and flammability of hdpe/ wood flour composites
in this study, the effect of nanoclay particles content on the physical properties and flammability of composite made of high density polyethylene and wood flour was investigated. for this aim, wood flour was combined with hdpe at 50% by weight, and nanoclay was used in 0, 2, 4 and 6%, also 2% of mape as the coupling agent was used in all formulations. the samples were made in injection molding...
متن کاملHigh-Temperature Hot Air/Silane Coupling Modification of Wood Fiber and Its Effect on Properties of Wood Fiber/HDPE Composites
The surfaces of poplar wood fibers were modified using high-temperature hot air (HTHA) treatment and silane coupling agent. The single factor test was then used to investigate the performances (e.g., the change of functional groups, polarity, cellulose crystallinity, and thermal stability) of modified poplar wood fibers (mPWF) through Fourier transform infrared spectrometry, X-ray diffraction a...
