Effect of PET functionalization in composites of rubber–PET–HDPE The plastic wastes, PET and hdpe, were purchased as small pellets with an average diameter of 1 cm from the Eco Green company (Romania), that processes plastic household wastes. The plastic wastes were further milled (centrifugal mill ZM 200, Retsch) to obtain grains with the average size of 1 mm with the following densities: for PET is 1.22 g/cm<sup>3</sup> and for hdpe is 0.89 g/cm<sup>3</sup>. In the composite development the tire rubber was used as matrix, PET as dispersed phase in the
Mold Resistance and Water Absorption of Wood/HDPE and Bamboo 22 Mar 2014 This study was conducted to clarify the mold resistance and water absorption of wood plastic composites (WPC). Wood/hdpe and bamboo/hdpe with different fiber content were used as test material. Mold fungi resistance (with or without biocide zinc borate (ZB)), scanning electron microscopy (SEM) analysis and water-absorption rate were investigated after 28 days incubation with Aspergillus niger, Trihoderma viride, Penicillium funiculosum and Aureobasidium
Study of Wood-Plastic Composites with Reused - Science Direct Traditionally, particle- reinforced composites are manufactured towards cost optimization of parts, whereas fibre and especially continuous fibre composites are designed towards increased mechanical performance. In this work, the incorporation of natural particles - sawdust - into a synthetic matrix - high density polyethylene - is studied. The composite material that emerges is called a Wood-plastic Composite, or WPC. The base materials were chosen because they both are waste.
Preparation and Properties of Wood Plastic Composites Made of This article deals with experimental investigation of composites based on recycled high-density polyethylene (Rhdpe) and poplar fibers (Populus deltoids) formed by air-forming and hot-pressing. The effects of the fiber content (55, 70, and 85 wt%) and compatibilizing agent (0, 2, and 4 wt%) concentration on the mechanical properties and water absorption were evaluated. The use of polyethylene-grafted maleic anhydride (PE-g-MA) improved the compatibility between the fiber and
Preparation of Wood Plastic Composite with - Semantic Scholar Abstrac: In this paper, the mechanical properties of high density polyethylene (hdpe grade 3840) produced by Bandare Imam- Iran, mixed with the wood and bagasse as fillers with 10-50 % w/w have been studied. The maximum tensile strength was observed at 10% w/w of fillers ratio. The elongation, impact strength and fracture energy were decreased with increasing of fillers ratio while the Young modulus and hardness were increased. Key words: Composite Wood Bagasse
High Density Polyethylene Composites Reinforced with Hybrid - MDPI 17 Sep 2013 For example, it was demonstrated that a pure high-density polyethylene (hdpe) or pure polypropylene (PP) shell over a wood polymer composites (WPC) core reduced moisture uptake compare tonon-coextruded NFPC. However, the addition of a pure plastic shell with a relatively low modulus and large thermal expansion over a WPC core negatively affected overall composite modulus and thermal stability [1,2]. Investigations have also been done to develop a.

Weathering of High-Density Polyethylene-Wood Plastic Composites 18 Sep 2013 Due to the widespread use of wood-plastic composites (WPCs), high-density polyethylene-wood flour composites (hdpe/WF) were studied in order to determine their stability in different application conditions. UV degradation and periodic absorption/desorption of moisture cause damaging changes to material during WPCs' exterior application, so it is necessary to ensure WPCs' durability against atmospheric influences. Samples were characterized by FTIR
Preparation and performance of high-density polyethylene-based 28 Feb 2017 In this study, by preparing red pottery clay according to unearthed red pottery clay pieces and using red pottery clay to reinforce high-density polyethylene-based wood–plastic composites, the effects of the amount of red pottery clay on the properties of the fabricated wood–plastic composites were investigated. The results indicated that when the amount of red pottery clay increased, flexural strength and impact strength of the composite initially increased and then

Study of Wood-Plastic Composites with Reused High Density The use of recycled thermoplastics has been considered for the production of wood and plastic composites in recent years . New materials have been developed with a view to developing eco-composites, materials with several advantages, both at an environmental level and an ecological level, including natural polymers. Solid plastic waste from polymers such as high density polyethylene is creating new challenges for an industry that is seeking greater waste utilization to
Dimensional stability and mechanical behaviour of wood–plastic This paper investigated the stability, mechanical properties, and the microstructure of wood–plastic composites, which were made using either recycled or virgin high-density polyethylene (hdpe) with wood flour (Pinus radiata) as filler. The post-consumer hdpe was collected from plastics recycling plant and sawdust was obtained from a local sawmill. Composite panels were made from recycled hdpe through hot-press moulding exhibited excellent dimensional stability as compared
Properties of wood plastic composites made of recycled HDPE and The feasibility of using recycled plastic and wood particles from chromated copper arsenate (CCA)-treated wood removed from service was investigated in this study. CCA pressure-treated red pine lumber removed from service after 21 years utilization was Wiley milled to wood flour and blended with virgin or recycled high-density polyethylene at 50:50 wood flour-to-plastic weight ratios. The blended materials were compression molded into panels and the physical and mechanical
