Investigation into the material properties of wooden composite

18 Jan 2017 In contrast to subtractive manufacturing techniques, additive manufacturing processes are known for their high efficiency in regards to utilisation of feedstock. However the various polymer, metallic and composite feedstocks used within additive manufacturing are mainly derived from energy consuming, inefficient methods, often originating from non-sustainable sources. This work explores the mechanical properties of additively manufactured composite structures  【Get Price】

Improvement of Mechanical Properties of Wood-Plastic Composite

A study is carried out on the structural design of wood-plastic composite floors. The geometric parameters of the cavities, the structure, and the means to optimize the performance of these light boards are investigated. Various structural parameters of the boards, such as size, shape, and the pattern of cavities are also studied. The optimal structure can be determined by calculation and analysis of the strength, stiffness, weight and cost of the material. A finite element model for the  【Get Price】

Wood-plastic composite - Wikipedia

In addition to wood fiber and plastic, WPCs can also contain other ligno-cellulosic and/or inorganic filler materials. WPCs are a subset of a larger category of materials called natural fiber plastic composites (NFPCs), which may contain no cellulose-based fiber fillers such as pulp fibers, peanut hulls, bamboo, straw, digestate, etc. Chemical additives seem practically "invisible" (except mineral fillers and pigments, if added) in the composite structure. They provide for integration of  【Get Price】

Physical and Mechanical Properties of WPC Board from Sengon

wood Plastic composite (WPC) is a composite material made from sawdust and plastic as polymer bonding, that used in a variety of structural and non-structural applications. Nowadays, In Indonesia WPC is made from Sengon sawdust and recycled HDPE plastic. This research was conducted in order to investigate the physical and mechanical properties of WPC from Sengon sawdust in accordance with ASTM D7031. From the physical test, due to its water restrains, WPC has low  【Get Price】

Composite Wood

OSB is frequently made by coating wood chips (known as strands) with MDI, then arranging consecutive strand layers roughly perpendicular to each other, and finally pressing the strands under high temperature and high pressure to form boards. These bonds form a chemical matrix that serves to glue the strands together. The perpendicular orientation of the wood strands imparts strength properties to the panels. OSB panels measure 4'x8' with thickness typically ?” to 23/32”. OSB is  【Get Price】
