physical and mechanical properties of wood-plastic composites

hybrid filler-reinforced composites are considered as high performance materials, but limited number of studies on hybridizations of wood fibers and mineral fillers were reported. three types of inorganic fillers (talc, kaolin, and zinc-borate), which have been widely adopted in various applications, were used for manufacturing wood–plastic composites (wpcs). the aim of this study is to understand the effects of filler shape, size, surface nature, and loading amount on the physical 【Get Price】

modifiers for wood plastic composites (wpc) - byk additives

mechanical properties of a wood flour-filled polypropylene wpc on wood content. with increasing wood content, e-modulus values increase but impact strength decreases. whereas an increase in the e-modulus is desirable, a reduction in the impact strength is certainly not. through the use of scona coupling agents, which significantly enhance the bonding of wood fibers with the polymer matrix, mechanical properties such as bending strength and impact strength of the composite 【Get Price】

evaluation of the acoustic properties of wood- plastic-chalk

abstract—wood-plastic composites are a new group of materials that can be used in construction instead of wood and plastic. they are used in various industries due to features such as sound and water absorption, among others. this article aims to study the acoustic properties of wood-plastic composites made of wood flour, low-density polyethylene, and chalk. in this study, 6 combinations were made with different material percentages. acoustic tests were performed for frequency 【Get Price】

wood-plastic composites as promising green-composites for - ncbi

18 dec 2007 wood-plastic composite (wpc) is a very promising and sustainable green material to achieve durability without using toxic chemicals. the term wpcs refers to any composites that contain plant fiber and thermosets or thermoplastics. in comparison to other fibrous materials, plant fibers are in general suitable to reinforce plastics due to relative high strength and stiffness, low cost, low density, low co2 emission, biodegradability and annually renewable. plant fibers as 【Get Price】
