Comparison Between Wood Plastic Composites(WPCs) And Woods

Abstract

Composites can be defined as materials that consist of two or more chemically and physically different phases separated by a distinct interface. The different systems are combined judiciously to achieve a system with more useful structural or functional properties non attainable by any of the constituent alone. This new materials are becoming an essential part of today's materials due to the advantages such as low weight, corrosion resistance, high fatigue strength, and faster assembly. They are extensively used as materials in making aircraft structures, electronic packaging to medical equipment, and space vehicle to home building like wood plastic composites. In this research we take a sample of wood plastic composites from moawia’s factory in Khartoum north and other samples are different types of wood to compare between them and define what is the best type of wood which gives a good mechanical properties by using tests like density, absorption test, hardness test, impact test and fire test. The tests where carried in Sudan university of science and technology. We found after making many experiment tests that the WPCs are resistance to water (absorption percentage 0.034% ) ,the density of it is 0.68g/cm3 ,hardness of it is 0.21 ,the impact of it is 1.24 and the burning test show that its good fire retardant 0.333 min .So the wood plastic composites are the best for using in different application. The musky is best one to use in compounding.
