Sintering Properties

According to its advantages, such as low-cost and green biological etc., Wood-Plastic Composite(WPC) is more suitable for make parts by Selective Laser Sintering(SLS) rapid prototyping (RP) process. With optimal design of components, the parts made by WPC have good mechanical properties as well as with good laser sintering properties. In order to further improve the surface quality of the parts, the post-processing–infiltrating with wax–is introduced. After post-processing, the void fraction is decreased from 51% to 7%, surface quality has been greatly improved, Ra belows 13µm on average, after polishing the surface is more smooth and Ra belows 5µm averagely，compared to those without post processing, surface roughness decrease 22% and 73% respectively.

This paper presents problem of the examination of the inhomogeneity of composite material on the base of wood plastic composite. It deals with evaluation of mechanical properties after tensile test and triax-bending test of a composite were assessed in relation to images acquired from radiographic method – metrotomography (using radiographic method which has an explanatory value in terms of evaluation of volume defects and in a figurative sense, also of the conduct of cracks on the surface after machining).

The objective of this study was to evaluate the surface quality of experimentally manufactured wood plastic composite (WPC) samples exposed to water soaking. Eastern redcedar (Juniperus virginiana L.), which is one of the invasive species in Oklahoma, USA, and recycled plastic were used to manufacture WPC samples. Three types of samples, namely with 0%, 3% and 6% nano-clay were soaked in water for up to one month. Stylus-type equipment was employed to evaluate their surface roughness as a function of water exposure. Two accepted roughness parameters, average roughness (Ra) and mean peak-to-valley (Rz), were used to determine changes in the surface quality of the specimens due to water exposure. Average roughness values of 1.5 µm and 4.1 µm were determined for the samples with no clay in dry conditions and those soaked for one month in water, respectively. Corresponding values were lower in the case of those with clay in their content. Based on the findings in this work, it appears that the stylus technique can be successfully applied to such samples to quantitatively evaluate their surface quality when they are exposed to water for an extended time span. It is expected that data from this work could help to produce a better understanding of the behavior of WPCs under environmental conditions.

This study aims to develop a new wood-plastic composite (WPC) material from recycled thermoplasctics. The recycled low-density polyethylene (rLDPE) and high-density polyethylene (rHDPE) were used as matrix, whereas the diatomaceous earth waste (D) and wood fiber (WF) as filler. Recycled-LDPE and rHDPE were recovered and pelletized by a plastic recycling process. The 10-30wt.% diatomaceous earth waste was heat-treated at 200°C to remove impurities. The diatomaceous earth, maleic anhydride grafted polyethylene (MAPE), CaCO3, slip agent, antioxidants and WF were then mixed at 160°C, for 10 minutes, at stirring speed 50 rpm to produce wood-plastic composite material. The mechanical strength and thermal properties of the composites were investigated. The composite containing D and rLDPE results in an increase the hardness of the material which is higher than that of the virgin-LDPE. The tensile and impact strengths of the composite material prepared by rLDPE and D were higher than those of the rHDPE composite material. It is found that LDPE has excellent fluidity, which is helpful for subsequent processing. In addition, the diatomaceous earth waste can be used to reduce the cost of the raw material, and the product has both effects of environmental protection and marketability.

Fiberglass Composite

One of the prevalent ways of machining is milling, however to obtain the high fiberglass composite surface quality is difficult because of its layered structure, high strength and low thermal conductivity characteristics. This leads to the need for milling technology which provides high-quality surface. Our experiments for milling of the fiberglass composite show that the surface roughness, as one of the quality criteria, to a large depends on cutting conditions, tool material and wear of the cutting edge determined by the bevel rear tool wear. To ensure of the surface quality of the composite material during milling recommended that the bevel rear tool wear does not exceed 0.35 mm, cutting conditions were the following limits: feed speed, 0.15 – 0.17 mm/cog, depth of the cut, 0.3 – 0.6 mm, cutting speed, 45 – 48 m/s and the cutting part of the tool is made of high strength tool materials such as hard metal VK3M.

Spreading Property

In this paper, powder spreading property in Wood-Plastic Composite(WPC) Selective Laser Sintering(SLS) rapid prototyping(RP) process is studied. WPC is more suitable for make parts by SLS according to its advantages, such as low-cost and green biological etc.. But as wood power is mainly composed of wood fiber and wood fibers have irregular shapes, easy to aggregate and block power spreading process, spreading powder uniformly on bed by leveling roller is difficult, resulting in bad shape quality of parts. In order to further improve powder spreading property of RP process, with optimal design of components, viscosity reducer calcium is added into WPC. Finally, as result of better powder spreading property, shape quality of the parts made by WPC is improved greatly and have good as well as with good laser sintering properties.
