Tiivistelmä
Today’s world is industrializing and heading towards development at a fast pace. Easiness of a life is the main motto of this generation. In order to provide maximum benefits plus fulfilling demands, day by day many new products are being manufactured. Many new raw materials have been building up and many cases they have already replaced the old raw materials to lower the price, giving more reliability, durability to the products. In a similar way, new composite materials have been made to enhance the material properties. Among them, Wood Plastic Composite (WPC) is the one.
Wood plastic composite is a mixture of wood flour and plastic fibers. It provides better properties than wood and plastic alone. For instance, wood plastic can be molded easily to any desired shape, but wood cannot be molded.
The main target of this thesis was to analyze and compare the tensile strength of welded wood plastic composites with non-welded wood plastic composites. Different filler wires using the hot gas welding procedure. Wood plastic composites with 70% High Density Polyethylene (HDPE) and 60% HDPE were adopted and filler wires like commercial PP, commercial PE, filament extruded polyethylene (PE) containing 10% cellulose, filament extruded polypropylene (PP) containing 10% cellulose and filler wire same as base materials.
Different filler wires played a vital role in weld strength. Filler wires needed to be of the same composition as of base material to provide better weld quality. Furthermore, the result showed that weld strength increases as increasing in plastic content in wood plastic composites.
