Description
Technical field
The present invention relates to a kind of streamlined reefer housing, particularly relate to a kind of carbon fiber composite pantograph air guide sleeve.
Background technology
In recent years, domestic high-speed rail transportation is in the high speed development stage, under " energy-conserving and environment-protective " theory is advocated in the whole world, namely require that train lightweight is to realize lower energy consumption, stronger transport capacity, can ensure again the safety of its operational process and the longer life of operation.Meanwhile, countries in the world all reduce the method for high speed railway pantograph noise in research.Wherein Application comparison widely method be on roof, install pantograph streamlined reefer housing additional, it is normally by glass fiber compound material, to stick with paste technique copy and make by traditional hand.But glass fiber compound material also exists density causes greatly the problems such as weight is excessive, intensity is little, with this, for how solving vehicle lightweight problem, and meeting the requirement of train to intensity, rigidity, fire-retardant and noise reduction, is the problem that should solve in the production process of streamlined reefer housing.
Summary of the invention
The density that the object of this invention is to provide the glass fiber compound material existed in a kind of carbon fiber composite pantograph air guide sleeve solution prior art causes greatly the problems such as weight is excessive, intensity is little, how to solve vehicle lightweight, and meet the problem of train to the requirement of intensity, rigidity, fire-retardant and noise reduction.
Technical solution of the present invention is:
A kind of carbon fiber composite pantograph air guide sleeve, described streamlined reefer housing is the case body structure of hollow, described streamlined reefer housing is that the composite material that matrix, glass fibre and carbon fiber are reinforcement is made with thermosetting resin, described streamlined reefer housing comprises cover body, mount pad and mounting hole cover plate, described cover body connects described mount pad, described cover body is cementing reinforced rib, described mounting hole cover plate is fixed by screws on cover body, described cover body is that split pattern vacuum imports global formation, and described reinforced rib is that vacuum importing is shaping.
Further improvement is: described cover body comprises fire-retardant gel coating resin and composite structural laminate, and described composite structural laminate comprises fibre reinforced layer and glass fiber reinforced layer.
Further improvement is: the percent by weight of described thermosetting resin is 35%-55%.
Further improvement is: the limited oxygen index of described thermosetting resin is more than or equal to 30.
Further improvement is: the weight ratio of described glass fibre and carbon fiber is 1-10:10-1.
