Physico-Mechanical Properties of Wood-Plastic Produced with Forest Species and Thermoplastic Materials

Abstract

This research aims to evaluate the physico-mechanical properties of wood-plastic composites produced with recycled polyethylene terephthalate, high-density polyethylene, low-density polyethylene and polypropylene, and sawdust from the following species: Pinus caribaea, Pinus cubensis, Cedrela odorata, Talipariti elatum and Eucalyptus sp. Composites were obtained by extrusion with dimension of 1,000 × 250 × 16 mm (length × width × thickness), through six treatments. The following physico-mechanical properties were evaluated: density, moisture content, water absorption and thickness swelling, compression, static bending and traction. Treatment 6 obtained the best results, with 1,060 kg m -3 density, 5.23% moisture content, 0.32% water absorption, and 0.18% thickness swelling. Compressive strength was 138.10 MPa, static bending 18.53 MPa, and traction 29.4 MPa. The technology developed has prospects for large-scale production.

Physicomechanical Properties of Sustainable Wood Plastic Composites of Tropical Sawdust and Thermoplastic Waste for Possible Utilization in the Wood Industry

“…These lacunae necessitate further work in this area if the opportunities offered by the subsequent production of useful materials from the sawdust obtained from these tropical timbers are to be maximized with respect to the WPC industry. Further research will provide useful information on new sources of raw material for the WPC industry and their effect on the products [14]. This work investigated and quantified the physicomechanical properties of the wood plastic composites produced from the sawdust waste of selected tropical timbers, namely, Nauclea diderrichii, Brachystegia eurycoma, Erythrophleum suaveolens and Prosopis africana and thermoplastic MSW like recycled PET and rPE for possible utilization in the wood industry.…”

Performance of eucalypt particleboard with the addition of farm waste

“…The union of different organic [ [12] , [13] , [14] , [15] ] and inorganic materials [ 16 , 17 ], if pressed under high temperature and pressure, can generate a panel resistant to physical or mechanical stress and xylophagous organisms, in addition to promoting better disposal of commercially undervalued waste through ecologically correct environmental management. Among several organic materials used in the composition of particleboards, along with wood, rice husk [ 15 , 18 ], sugarcane bagasse [ 19 ], wheat bran [ 20 ], coffee fiber [ 21 ], bamboo waste [ 22 ], sunflower stalks [ 23 ] and, in particular, eggshell, stand out [ 24 ].…”

Upcycling of waste artificial turf forhigh‐performancewood‐plastic composites

“…8,9 As a kind of biomass materials, woodplastic composites combine the advantages of wood and plastic, which are used in environments where traditional wood products cannot be used for solving the problem that wood products are easy to rot and deform after absorbing water in a damp environment. [10][11][12][13] The use of plastic waste with a single component as the matrix for wood-plastic composites has been considered an effective method to the plastic circular economy. However, due to the poor compatibility of each component in the WAT and the poor dispersibility of wood flour (WF) in the WAT matrix, the use of WAT in the woodplastic composite material is a challenging task.…”

“…With its renewability, biomass resources have been widely concerned and have been used in the preparation of various materials 8,9 . As a kind of biomass materials, wood‐plastic composites combine the advantages of wood and plastic, which are used in environments where traditional wood products cannot be used for solving the problem that wood products are easy to rot and deform after absorbing water in a damp environment 10–13 . The use of plastic waste with a single component as the matrix for wood‐plastic composites has been considered an effective method to the plastic circular economy.…”
