3D printing has rapidly become popular in both industry and private use. Especially fused deposition modeling has increased its popularity due to its relatively low cost. The purpose of this study is to increase knowledge in the mechanical properties of parts made of wood-plastic composite materials by using 3D printing. The tensile properties and impact strength of two 3D-printed commercial wood-plastic composite materials are studied and compared to those made of pure polylactic acid. Relative to weight –mechanical properties and the effect of the amount of fill on the properties are also determined. The results indicate that parts made of wood-plastic composites have notably lower tensile strength and impact strength that those made of pure polylactic acid. The mechanical properties can be considered sufficient for low-stress applications, such as visualization of prototypes and models or decorative items.

Shell Composite

In order to improve the properties of a co-extruded wood-plastic composite (WPC), different types of cellulosic fibres, pulp cellulose (PC), a combination of PC/microfibrillated cellulose (MFC) and wood flour (WF) with different size were introduced into shell layer based on a polypropylene (PP) matrix. The combination of PC/MFC improved the tensile properties compared to PC alone; but the impact strength was independent on the MFCs content. The presence of MFCs did not influence the water absorption (WA), but thickness swelling (TS) increased, however. The properties of the WF/PP-shell composite were highly affected by the WF particle size. The 20-mesh-sized WF-loaded composite had weaker mechanical properties compared to the smaller sized, Arbocel C320, shell-layer filled WPC. Also, Arbocel C320/PP-coated WPC had the highest tensile properties among all studied composites. The morphology of the composites was examined with a scan electron microscope.

Comprehensive Property

The relationship between properties of BF-WPC and the content of BF were studied, when wood-plastics composite (WPC) was reinforced by 12 mm and 3 mm short basalt fiber (SBF). The results showed that there may have some uneven distributions of SBF in WPC, when the content of 12 mm BF exceeded 30%. Restricted to the uneven distribution and the quantity of “end weak’’, it formed the close comprehensive property of BF-WPC by the length of 12mm and 3mm BF. The comprehensive property of BF-WPC has a maximum range of 15%-30% of the content of 12 mm BF. Compared to pure WPC, the tensile and bending strength of BF-WPC have improved. However, the reinforce effect of BF-WPC is different and is dependent on the index of each property. The BF-WPC plate can be developed with different properties and be a cost-effective material by choosing different length and content of BF.

This study focused on the design of wood-plastic composite (WPC) products. In this study, recycled high-density polyethylene plastic was used as the matrix, wood powder was used as the filler, different types of nanofillers and self-synthesized nanofiller treatment agents were added, and the twin-screw extrusion granulation method was used to prepare nano-WPC materials. The effects of different types of nanofillers on the mechanical properties of nano-WPC materials were investigated, and the cross-sectional structures of the materials were analyzed by scanning electron microscopy. The results showed that nanofiller treatment agents improved the interface compatibility of the materials. When the treatment agent content reached 2.5% and the nano-montmorillonite content reached 10%, the mechanical properties of the material reach their maximum values.

Specific Material

Wood plastic composite (WPC) materials represent modern materials that are attracting interest worldwide. WPC are composite materials and they have properties of both components – plastic and wood. WPC materials are formed by combining two substances – discontinuous reinforcements (wood particles or cellulose microfibers) and a continuous binder (plastic matrix), in a certain proportion. The authors describe WPC machined surfaces after turning. On the basis of a set of experimental data collected by surface and mechanical tests obtained from the WPC materials, the mechanical deformation work was evaluated, the value of which presents specific information about the material as a specific material coefficient.
