Wood Polymer Composite

In this work the research of new wood polymeric composite material as which filler timber industry waste in the form of sawdust, shaving, spill, lumpy waste and polyethyleneterephthalate, a research of its frost resistance by means of a method of a computer experiment is used is considered. A computer program has been developed to simulate the structure and physical properties of building blocks made of wood polymer composite material. The program allows you to set geometric and physical parameters of the building block and material components in the windows of the interface form in program code, as well as test conditions for cyclic heating and cooling to temperatures maximum possible during operation, and investigate the influence of parameters on the internal and surface destruction of the building block. The program is applicable for a wide range of concentrations of composite components, geometric parameters of the building block, various mechanical and thermocyclic tests. Influence of composition of wood polymer composite material on structure in thermocyclic tests is investigated. Dependencies of broken bonds on concentration of wood, cartogram of breaking bonds of wood polymer composite material with concentration of wood from 20 to 80% are obtained.

Wood Polymer Composite

The article describes a new multilayer wood-polymer composite material, the outer layer of which comprises wood flour, polypropylene, polybutadiene, concentrated dye. The inner layer comprises longwise oriented wood particles of the fibrous type of 2-10 mm and the recycled thermoplastic polymer. An experimental complex used to identify structural and operational characteristics of the composite material was presented. The experimental study of the mechanical properties of the product hardness, abrasion, cross-breaking strength were conducted. The results of the tests selected and validated the composite structure.

Compression Resistance

In this work, a wood composite material is considered, which incorporates all the best properties of the known wood polymer composites: water resistance, moisture resistance, high bending strength. It was concluded that according to the criterion of resistance to temperature fluctuations, it is possible to give more complete recommendations on the optimal composition of the wood polymer composite material based on a two-factor study. To ensure comparability of optimization results for a number of other properties, a series of computer experiments was carried out according to the same plan as for the study of compression resistance, that is, the concentration of wood and at the same time the concentration of sand was changed from 10 to 50 % with a step of 10 %, respectively. The material has acquired new advantages, which do not have known analogues – the possibility of using any wood waste, higher strength due to the content of sand in the composition, cheaper production due to the fact that most of the components of the material are household and wood waste, namely waste from the woodworking and forestry industries in the form of chips, sawdust, chips, lump waste, as well as sand, which is a publicly available and inexpensive material.

Abstract Purpose Waste recycling is one of the essential tools for the European Union’s transition towards a circular economy. One of the possibilities for recycling wood and plastic waste is to utilise it to produce composite product. This study analyses the environmental impacts of producing composite pallets made of wood and plastic waste from construction and demolition activities in Finland. It also compares these impacts with conventional wooden and plastic pallets made of virgin materials. Methods Two different life cycle assessment methods were used: attributional life cycle assessment and consequential life cycle assessment. In both of the life cycle assessment studies, 1000 trips were considered as the functional unit. Furthermore, end-of-life allocation formula such as 0:100 with a credit system had been used in this study. This study also used sensitivity analysis and normalisation calculation to determine the best performing pallet. Result and discussion In the attributional cradle-to-grave life cycle assessment, wood-polymer composite pallets had the lowest environmental impact in abiotic depletion potential (fossil), acidification potential, eutrophication potential, global warming potential (including biogenic carbon), global warming potential (including biogenic carbon) with indirect land-use change, and ozone depletion potential. In contrast, wooden pallets showed the lowest impact on global warming potential (excluding biogenic carbon). In the consequential life cycle assessment, wood-polymer composite pallets showed the best environmental impact in all impact categories. In both attributional and consequential life cycle assessments, plastic pallet had the maximum impact. The sensitivity analysis and normalisation calculation showed that wood-polymer composite pallets can be a better choice over plastic and wooden pallet. Conclusions The overall results of the pallets depends on the methodological approach of the LCA. However, it can be concluded that the wood-polymer composite pallet can be a better choice over the plastic pallet and, in most cases, over the wooden pallet. This study will be of use to the pallet industry and relevant stakeholders.
