Description
technical field
The utility model belongs to technical field of polymer composite materials, is specifically related to a kind of fiber reinforcement composite sleeper.
Background technology
The sleeper that rail track is used is at present mainly sleeper and prestressed reinforced concrete sleeper.Known sleeper, because it has good springiness, is easy to processing, the advantage such as easy to use, is used widely in special locations such as bridge, track switches.But owing to drawing materials, the intensity of sleeper and durable even not, can strengthen dynamic action between wheel and rail, makes the application life of sleeper short.In addition, high-quality timber resources is deficienter, does not also more and more meet environmental protection and ecological protection requirement.Known prestressed reinforced concrete sleeper, due to its abundant raw material, is easy to guarantee manufactured size, and quality is large, the life-span is long, and can improve the stability of track, therefore in railroad track, obtains extensively a large amount of use.But prestressed reinforced concrete sleeper also exists the drawbacks such as poor flexibility, rigidity are large, in specific region or position use and limited to.
For commonly using at present the open defect that sleeper and prestressed reinforced concrete sleeper have, the composite sleeper of long fiber reinforcement foamed resin material is a kind of good replacement material.Long glass fibres enhanced foaming resin has the structure similar to natural timber, can be used as building and ornament materials, means of transportation replacement timber.But long fibre only provides the axial strength of material, its transverse strength is still lower, therefore, and while adopting the composite sleeper of long fiber reinforcement foamed resin material to be laid on the rail that railway uses, rail tie plate easily weares and teares, and also formation is sagging on sleeper surface, affects the safety of track.Number of patent application is in 200610082833.2 public announcement of a patent application manual; disclosed the manufacture method of a kind of synthesis wooden sleeper and synthesis wooden sleeper; this sleeper is using the foaming mother metal by long fiber reinforcement foamed resin material foaming as main body, and uses without foamed resin material and be integrally formed topping on main body top layer.Although use without foaming resin-shaped, become the method for topping can increase the abrasion performance of material, reduced the effect of foaming mother metal damping noise reduction simultaneously, increased vibrations and the wearing and tearing of rail, wheel.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model proposes a kind of fiber reinforcement composite sleeper, can meet the high strength of bearing structure material, the requirement of high elastic modulus, has the feature of good endurance, damping noise reduction and fire protection flame retarding simultaneously.
For completing above-mentioned purpose, the utility model adopts following technical scheme:
A fiber reinforcement composite sleeper, described composite sleeper has the foaming mother metal by foamed resin material and continuous fortifying fibre foaming; The upper surface of described foaming mother metal has topping; Described topping is by foamed resin material and the fiber reinforced material foaming that is positioned at expanded material.
Described foamed resin material is one or more the mixing in polyurethane foam material, Foaming of phenolic resin material, epoxy resin expanded material.
Described continuous fortifying fibre is one or more in alkali-free glass fibre rove, medium-alkali glass fibre rove, carbon fiber, aramid fiber, superhigh molecular weight polyethylene fibers.
Described fiber reinforced material is one or more in glass fiber woven cloth, glass fibre non-woven, aryl fiber cloth, carbon cloth.
Described topping is foaming-formed with foaming mother metal.
Described topping is integral by bonding adhesive is bonding with foaming mother metal.
During described topping moulding, in it, sneak into not firing or nonflammable material of liquid or powdery, form the flame retarding construction of described topping.
A kind of fiber reinforcement composite sleeper the utility model proposes, adopt technique scheme, in foaming mother metal, there is continuous fortifying fibre, it is good that continuous fortifying fibre has resin wellability, the advantage that bending strength is large, and arrange along composite sleeper length direction, adopt continuous fortifying fibre enhanced foaming parent to there is defect few, bending strength highland advantage, has met the high strength of bearing structure material, the requirement of high elastic modulus, topping consists of foamed resin material and the fiber reinforced material that is positioned at foamed resin material, fiber reinforced material is woven cloth, nonwoven or three dimensional fabric, fiber reinforced material have advantages of compressive strength and shear strength high, and fiber is along composite sleeper length, width and all directions such as oblique are arranged, the topping that adopts fibrous material to make has incompressible, shock resistance, the advantage that friction resistant is sheared, make the abrasion performance of composite sleeper, impact resistance performance significantly improves, composite sleeper still can keep as the necessary intensity of bearing structure material through long-time use, there is excellent durability, because topping is foamed resin material, therefore, above-mentioned composite sleeper has the function of damping noise reduction, in topping, sneak into the incombustible material of liquid or powdery, or the difficulty of incombustible agent combustion layer, therefore, for the heat from outside or burning things which may cause a fire disaster, composite sleeper can not fire or difficult burning, therefore, with for incombustible material that the not burning of composite sleeper integral body needs or the component of incombustible agent are compared, as long as can give desired flame retardant property on a small quantity, so reduced manufacturing cost.
Accompanying drawing explanation
