Require.But, there is intensity in wood plastic composite and shock resistance is relatively low, and the easily shortcomings such as creep, in Structural Engineering
The application of Material Field is restricted, and when being used as supporting part, the processing method of most at present businessmans is at hollow wood
Moulding and inserting shaped steel increase intensity in inner chamber, this mode has not only increased considerably the cost of raw material, and has brought to construction
Very burden, too increases construction cost.Therefore, it is extremely necessary for preparing high-performance wood-plastic composite material, is directly connected to
The development of wood plastic composite industry.
Adding a kind of method that reinforcement fiber is effective enhancing composite property, high-intensity fiber is that composite is commonly used
Reinforcing material, himself physical and mechanical property is very high.Chopped carbon fiber is currently mainly used to strengthen wood plastic composite, but
There is a lot of problem, as current preparation method and equipment can not make fiber preferably disperse in the composite, easily reunite and produce
Raw stress concentration point, thus destroy the continuity of material, cause strengthening DeGrain.Also researcher is had to attempt utilizing continuously long
Fiber reinforcement wood is moulded and preparation method thereof, including surface modification continuous glass fibre, granulation, three steps of extrusion, at extruder
Continuous fiber is added, it is ensured that the continuity of fiber by the position punching of merging core.But this method is from extruder merging core position
Adding fiber, only ensure that the continuity of fiber, fiber is uncontrollable in the position of composite inner and state, and fiber is easily rolled into a ball
Poly-, thus form internal flaw.Secondly, fiber is not carried out preheating and tension process by extrusion, causes fiber-reinforcing effect
Reduce.
