Properties of wood plastic composite panels made from waste sanding dusts and nanoclay

Abstract

This article presents the application of waste sanding dusts in order to evaluate its suitability as reinforcement for thermoplastics as an alternative to wood fibers. The effects of sanding dust loading and nanoclay content on the physical and mechanical properties were also studied. Overall trend showed that with addition of sanding dusts, tensile and flexural properties of the composites were significantly decreased, due to the reduction of interface bond between the fiber and matrix. It was found that flexural, tensile and withdrawal strength of fasteners were moderately enhanced by the addition of 2 wt% nanoclay in the matrix. However, with increase in the nanoclay content (4 and 6 wt%), the flexural and tensile properties decreased significantly. The results also showed that the withdrawal strengths of screws are much higher than those of nails. At certain amount of sanding dust, with increasing nanoclay loading the withdrawal strengths of fasteners (screws and nails) were considerably decreased. The thickness swelling and water absorption of the composites dramatically decreased with the increase in nanoclay loading. Except thickness swelling, both variable parameters (sanding dust and nanoclay contents) showed significant influence on physico-mechanical properties.

A comparison of various ionic surfactant modifiers used in in situ synthesis of organo-montmorillonite inside wood flour

“…Madhoushi et al (2014) uptake and thickness swelling were significantly reduced due to OMt occupying some voids of the composites. Besides, owing to the improved interfacial bonding between WF and polymer matrix, the mechanical properties of the composites increased a lot (Zahedi et al, 2013).…”

A comparative study on the effects of material blending method on the physico‐mechanical properties of WPCs made from MDF dust

“…Wood–plastic composites (WPCs) have been introduced successfully to the academic sectors due to considerable processing advantages and improvement in certain physical and mechanical properties during the previous decades . Materials now known as WPCs first appeared in the 1960s .…”

“…Materials now known as WPCs first appeared in the 1960s . For making WPCs, the lignocellulosic fibers may be obtained from wood species or agro‐based fibers . Currently, most WPC is for use in exterior building component and building panels, including decking, roofline products, windowsills, flooring material for trucks, standard containers, playground equipment, fencing, industrial flooring, landscape timbers, and railing .…”

“…The presence of wood in a plastic matrix can result in a stiffer and lower‐cost material than if plastic alone were used . According to different the manufacturing techniques, the dominant technologies to produce WPCs are extrusion to obtain unlimited profiles and injection molding leading to three ‐ dimensional forms, so the width of WPCs with this manufacturing method is limited to a nearly 1.2 – 1.8 m . Another possibility is producing WPCs on a flat ‐ press .…”

Minimizing the creep of recycled polypropylene/rubberwood flour composites with mixture design experiments

“…They found that the composites with a high fraction of RNF had high water absorption. Madhoushi et al 18 studied the effects of sanding dust loading and nanoclay content on the physical and mechanical properties of polypropylene. Addition of sanding dust significantly decreased tensile and flexural properties of the composites, and flexural, tensile, and withdrawal strength of fasteners were improved by the addition of 2 wt% nanoclay in the matrix.…”
