weathering characteristics of wood plastic composites reinforced

23 jul 2016 this study investigated weathering performance of an hdpe wood plastic composite reinforced with extracted or delignified wood flour (wf). the wood flour wood fiber swells after absorbing moisture and creates cracks in the plastic matrix which contribute to the loss of composite moe and strength. moisture also each extraction process was performed for 24 h in a soxhlet apparatus (corning inc. new york ny usa) to ensure exhaustive removal of extractives.【Get Price】

mechanical and time-dependent behavior of wood–plastic

the thermoplastics within wood–plastic composites (wpcs) are known to experience significant time-dependent deformation or creep. in some formulations creep deformation can be twice as much as the initial quasi-static strain in as little as 4 days. while extensive work has been done on the creep behavior of pure polymers little information is available on the mechanical effects of mixing polymers with large amounts of wood-based or other bio-based fillers. as producers seek to 【Get Price】

assessment of defect detection in wood–plastic composites via

abstract. in this research work the possibility of defect detection in wood–plastic composites. (wpcs) by shearography method has been assessed. shearography is one of the practical nondestructive test methods that has been commonly used for detecting defects in polymer-based composites. in this experimental work first a defect (hole) was inten- tionally drilled on one side of the extruded wpc and then the shearography test and analysis was performed on it. this preliminary 【Get Price】
