Description

A kind of composite panel, Preparation method and use

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, due to its high specific strength and specific stiffness, are widely used in engineering field.But this type of composite impact loading is more responsive, in use the most fatal damage often causes because impacting.When impact velocity is very high, composite laminated plate will be penetrated; And when impact velocity reduces, different failure mode can be produced, such as 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 major part composite does not once cause, often material failure after repeatedly low energy impacts.When composite is in use subject to low energy impact, the not obvious visual damage of major part situation, but generate not visible shallow skin lamination at laminated surface, thus form potential danger, the existence of internal injury can cause the extreme loss of composite on Rigidity and strength.

Road transport car amount mainly delivers ore, coal cinder, sandy soil and metal material etc., and compartment and goods directly contact, continual low speed or the high speed impact of standing in transportation and handling procedure, various frictional impact occurs simultaneously and between goods.Therefore, require that the parts such as compartment need enough intensity, toughness and wearability.

Although the metal materials such as iron and steel can meet the user demand of haulage vehicle, because its density is large, haulage vehicle is conducted oneself with dignity comparatively large, decrease the ability that it carries cargo.At present, the lightweight demand of haulage vehicle is brought into schedule, and using composite to carry out loss of weight to haulage vehicle also becomes study hotspot, but composite focuses mostly in the exterior trimming parts such as panel, vehicle body of truck-tractor part.This is because fibrous composite self toughness is poor, caused by being difficult to experience a shock and rub.

For composite board or wear-resisting high-impact sheet material, application number is that the Chinese patent of 200810013963.X has been reported for work a kind of impact-resistant abrasion-proof lining board: this liner plate comprises polyurethane plate body, the top layer heat cure of polyurethane plate body has multiple alumina balls, the bottom of polyurethane plate body is connected with steel plate by reinforcing network, and reinforcing network is connected with Interal fixation and reinforces in heat cure and polyurethane plate body; Steel plate is provided with back of the body nail, and full in back of the body nail have the polyurethane with polyurethane plate body one.It is coated that steel plate periphery is provided with polyurethane, and polyurethane sheet and steel plate are connected firmly, and has impact and close wearability, is applicable to the transport such as mine, harbour magazine and hopper etc.The abrasion-proof backing block that this patent uses is still reinforcement with steel plate, is difficult to reach lightweight object.

Application number be 200510029570 Chinese patent report a kind of fibrous composite that uses and manufacture the method for automobile panel, this automobile panel is formed by fiber reinforcement outside plate, foam or comb core and the three layers of splicing of fiber reinforcement inner panel, there is light-weighted effect, but this composite panel can only can not as load-carrying construction part as covering, and inner and outer plates and core adopt the form of glueing joint, add manufacture link, the production cycle is long.Patent WO2009/096676 a kind of composite that uses of having reported for work passes through the vehicle body simultaneously solidify to form, vehicle body uses filled board global formation, filled board comprises leather material and skin material and the sheet metal between core and skin material in core, fiber prepreg material, manufacture method uses lamination and autoclave method, this invention solves the plate surface mass defect problem with core, adds somewhat to rigidity and the toughness of material simultaneously, but still only can as body outer skin, can not as supporting part.

Polydicyclopentadiene is the macromolecular material that a class has excellent mechanical performance, has been applied to manufacturing certain parts on vehicle, and mostly its synthetic method is the reaction injection molding method (RIM) adopting two component, as Chinese patent ZL97106423.7.Not yet have about the fibrous composite containing polydicyclopentadiene layer at present.

Summary of the invention

In order to overcome existing fibrous composite erosion-resisting characteristics and anti-wear performance poor, be not suitable for for vehicle load or weight bearing area, a kind of novel, composite board that lightweight, performance are good be provided, the object of this invention is to provide a kind of composite panel.
