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.

Mechanical properties of wood plastic composite, prepared from acrylate-styrene-acrylonitrile (ASA) and bagasse, were investigated. In this study, 10 to 50 phr of bagasse were used in order to obtain the wood plastic composite with superior mechanical properties. The wood plastic composites in the study were prepared by melt-blending technique. All materials were mixed by using a two-roll-mill, shaped into sheets by a compression molding machine and the specimens were cut with a cutting machine. Youngs modulus, flexural strength, flexural modulus, impact strength and hardness of the wood plastic composites were investigated and found to improve with increasing bagasse content. However, some composite properties, i.e., impact strength, was decreased by adding the bagasse and then become steady when the amount of bagasse added was more than 30 phr. It was concluded that wood plastic composites with the desirable mechanical properties can be formulated using ASA as the matrix polymer and 50 phr of bagasse.

Wood-plastic composites are a group of materials with potential to penetrate markets currently dominated by plastic or wood products. The surface properties of wood-plastic composite materials have been found to be similar to those of polyolefin materials, thereby presenting a challenge to the use of adhesive joining methods. Plasma chemistry can be performed to improve the adhesive properties of polyolefin materials. In this research, the effect of atmospheric plasma treatment on polypropylene and spruce (Picea abies) wood-plastic composite surfaces is investigated by contact angle measurement with sessile drop method and tensile strength tests of glued samples. The plasma treatment is performed on extruded WPC profiles. Confocal Raman microscopy and scanning electron microscopy are used for analysis of the material surface. The results show an increase in the contact angle of plasma treated WPC materials and an improvement in the tensile strength of glued samples following plasma treatment. Observation of the Raman spectrum indicates an increase in polar groups after plasma treatment. Scanning electron microscopy shows changes in the surface of the treated samples, which can be seen as increased porosity, possibly due to etching as a result of the plasma treatment. It is concluded that atmospheric plasma treatment for adhesion improvement of WPC materials can therefore be applied successfully, although it has a mechanical effect on the surface of the material.

The potential of recycled wood flour (r-WF) addition to the thermoplastics polypropylene (PP) matrix for the composites in structural application is evaluated. The effects of different r-WF loading to the tensile and impact mechanical structural properties are analyzed. Two types of polypropylene resin which are the virgin and the recycled resin and recycled wood flour as reinforcement materials are utilized as raw materials in the composites fabrication. Various mechanical testing was conducted in accordance to ASTM standard, to study the behavior of the composites mechanical properties to the applied load. The best compounding formulation of enviro-recycled composite was found at 60wt% of PP matrix and 40wt% of the wood flour addition for both of virgin and recycle matrix. Overall experimental results showed that, the increasing of r-WF loading had significantly increased the mechanical properties of produced composite which is suitable to be applied in the application of structural engineering, through the advantage of mechanical properties performance in tensile and impact behavior. Conclusively, this finding is hoped to lead for contribution in the development of newly advanced material that is environmental friendly for the use of structural application.

In this study, ethylated wood powder/polystyrene plastic composite (WPC) was obtained by combining ethylated Chinese Fir powder with polystyrene foam in DMF or CHCl3, and was dyed with disperse dyes. The results show that the compatibility of ethylated fir powder with polystyrene was good when the ratio of wood to plastic ratio is beyond 3:1. The color shade of dyed wood-plastic powder is close to that of dyed polyester fabric and high temperature is favorable for the dyeing of wood-plastic powder. Moreover, dyed wood plastic powder has good washing fastness, which depends on the molecular structure of disperse dyes, dye concentration and dyeing temperature.

Welded joint is observed by scanning electron microscope and its connection status is analyzed. Experiment results show that ultrasonic welding technology can be applied to T-type wood-plastic composites component, which has enough tensile strength.

The aim of this study is to investigate the effect of maleic anhydride on mechanical properties of wood plastic composites using acoustic emission monitoring and wavelet analysis. Wood plastic composite samples were prepared by combining olive wood sawdust as reinforcing material with volume fraction of 40 wt% up to 60 wt% with polyethylene as matrix phase. Maleic anhydride with weight ratio of 1 to 3% as a coupling agent and stearic acid with weight ratio of 1% as a lubricant agent were used in all the compounds. Wood plastic composite samples were manufactured using extrusion and injection molding process in accordance with ASTM D638. Once specimens were produced, tensile tests were carried out in order to characterize their tensile properties. Results demonstrated that wood plastic composite sample containing 40 wt% sawdust and 3 wt% maleic anhydride possesses highest tensile strength. This experimental work established the criteria for the lower amount of reinforcement material and higher amount of compatibilization agent in improving mechanical properties. Failure micro-mechanisms were characterized by wavelet analysis of acoustic emission data. Ultimately, the experimental tests were proved by the scanning electron microscope observations.

The improvement in impact properties of wood plastic composite from acrylate-styrene-acrylonitrile (ASA) and bagasse was reported in this work. The effect of type and content of impact modifier by using styrene-butadiene-rubber (SBR) and ethylene-acrylic acid (EAA) as impact modifier on morphology and mechanical properties of wood plastic composite were investigated. Wood plastic composites, prepared from ASA and 50 phr of bagasse by varying amount of impact modifier (both SBR and EAA) from 0-40 wt% of ASA were prepared by melt-blending technique. All materials were mixed by using a two-roll-mill, shaped into sheets by a compression molding machine and specimens were cut with a cutting machine. Then, the obtained materials were characterized, including morphology, impact strength and flexural properties. From SEM micrographs showed that wood plastic composites with using SBR as impact modifier showed more compatible with ASA matrix than EAA. This is a consistency results with mechanical properties such as impact properties, which indicated that the impact strength was improved with increasing the amount of SBR from 0-40 wt% of ASA. However, wood plastic composite with EAA showed the reduction of impact strength. So, it could be demonstrated from this study that the most appropriate impact modifier for wood plastic composite from ASA and bagasse was styrene-butadiene-rubber.
