Description
Technical field
The present invention relates to composite panel and preparation method thereof, be specifically related to a kind of anti-impact, wear-resisting fibre reinforced materials composite plate, and its production and use.
Background technology
Fibre reinforced composites are because its high specific strength and specific stiffness have been widely used in engineering field.But this type of composite impact loading is relatively more responsive, and in use the most fatal damage often causes because of impact.When impact velocity was very high, composite laminated plate will be penetrated; And when impact velocity reduces, can produce different failure modes, for example MATRIX CRACKING, fibrous fracture and layering.So to reinforced composite structure security threat maximum be impact injury, impact injury is the main study subject of damage of composite materials.
The damage of most of composite does not once cause, often through material failure after the low energy impacts repeatedly.When composite in use is subject to low energy impact, most of situation does not have obvious visual damage, but generate not visible shallow skin lamination at laminated surface, thereby form potential danger, the existence of internal injury can cause the very big loss of composite on Rigidity and strength.
Road transport mainly delivers ore, coal cinder, sandy soil and metal material etc. with the car amount, and the compartment directly contacts with goods, and various frictional impacts occur between while and the goods continual low speed or the high speed impact of standing in transportation and handling procedure.Therefore, require the parts such as compartment to need enough intensity, toughness and wearability.
Although the metal materials such as iron and steel can satisfy the user demand of haulage vehicle, because its density is large, so that the haulage vehicle deadweight is larger, reduced its ability that carries cargo.At present, the lightweight demand of haulage vehicle is brought into schedule, and using composite that haulage vehicle is carried out loss of weight also becomes study hotspot, but composite focuses mostly in exterior trimming parts such as the panel of truck-tractor part, vehicle bodies.This be since fibrous composite self toughness relatively poor, be difficult to experience a shock and rub due to.
For composite board or wear-resisting high-impact sheet material, application number is the Chinese patent of 200810013963.X a kind of impact-resistant abrasion-proof lining board of having reported for work: this liner plate comprises the polyurethane plate body, the top layer heat cure of polyurethane plate body has a plurality of alumina balls, the bottom of polyurethane plate body is connected with steel plate by reinforcing network, and reinforcing network is fixedly connected with and reinforces with steel plate in heat cure and the polyurethane plate body; Be provided with back of the body nail hole at steel plate, back of the body nail fills the polyurethane that has with polyurethane plate body one in the hole.The steel plate periphery is provided with polyurethane and coats, and polyurethane sheet is connected firmly with steel plate, has impact and closes wearability, is applicable to mine, harbour etc. and transports magazine and hopper etc.The abrasion-proof backing block that this patent is used still take steel plate as strengthening body, is difficult to reach the lightweight purpose.
Application number is that 200510029570 Chinese patent has been reported a kind of method of using fibrous composite to make automobile panel, this automobile panel is to be formed by fiber reinforcement outside plate, foam or comb core and three layers of splicing of fiber reinforcement inner panel, has light-weighted effect, but this composite panel can only can not be as load-carrying construction spare as covering, and inner and outer plates and core adopt the form of glueing joint, increased the manufacturing link, the production cycle is long.The patent WO2009/096676 a kind of vehicle body of composite by solidifying to form simultaneously that use of having reported for work, vehicle body uses the filled board global formation, filled board comprises leather material and skin material and the sheet metal between core and skin material in core, the fiber prepreg material, what manufacture method was used is lamination and autoclave method, this invention has solved the plate surface mass defect problem with core, rigidity and the toughness of material have been increased to a certain extent simultaneously, but still only can be as body outer skin, can not be as supporting part.
Polydicyclopentadiene is the macromolecular material that a class has excellent mechanical performance, has been applied to making certain parts on the vehicle, and mostly its synthetic method is to adopt the reaction injection molding method (RIM) of two components, such as Chinese patent ZL 97106423.7.At present not yet relevant for the fibrous composite that contains the polydicyclopentadiene layer.
Summary of the invention
