Abstract
The invention relates to a fiber reinforced composite material section having a double-layer structure and is particularly applicable to pultruded and protruded sections with constant cross sections. A plastic-coated composite material section comprises a tube having different section shapes, a solid bar material having different section shapes, a special material having different section shapes and the like; and the plastic-coated composite material section is applicable to structural pieces such as an umbrella column and a framework of a sun umbrella, glass steel doors and windows, furniture and the like, so an aim of substituting plastic for woods and steel is fulfilled. The inner layer of the double-layer section is a fiber reinforced composite material section, and the outer layer of the double-layer section is a high-molecule material coating layer.
Description
Technical field
The present invention relates to a kind of composite material section bar, comprise tubing, bar and profile shapes.
Background technique
Fibre-reinforced polymer matrix composites with the characteristics of its high-strength light in the application of every profession and trade more and more widely.Wherein the consumption of the various section bars of being made by continuous pultrude process is also increasing, mainly comprises the bar of the tubing of various bores and sectional shape, various diameter and sectional shape and the special-shaped material of various sectional shapes.
The tension and the resistance to flexure of molded through pultrusion of composite material section bar are very good, but its compressive strength is then lower.The drawing and extruding section bar that particularly adopts continuous fiber to strengthen, fine along the mechanical strength of fiber orientation, perpendicular to the then greatly reduction of mechanical strength of fiber orientation direction.When the molded through pultrusion of composite material section bar had the structural member of resistance to compression requirement in conduct, cracking phenomena often appearred easily.In addition, it is exactly that wherein small amount of fibers floats on material surface that fibre reinforced composites also have a shortcoming, can cause skin urtication, so generally be not suitable for directly applying in the consumer goods.
If the plastic materials that one deck has certain mechanical strength is wrapped up in the outside at above-mentioned fibre reinforced composites drawing and extruding section bar, then can overcome described two shortcomings simultaneously.Such double layer construction had both kept good tension and the resistance to flexure of fibre reinforced composites, had strengthened impact strength and splitting resistance simultaneously greatly.Also avoided the pollution of surface fiber.
Surrounding layer can adopt the production of plastics expressing technique, and the section bar internal layer that makes is pushed into extrusion die die orifice, and the melt plastic cement melt that extruder is extruded is coated on section bar internal layer outside and forms surrounding layer.Can make the product that needs through typing, cooling, cutting.The surrounding layer that expressing technique is made is after cooling is shunk, and its coating dynamics is very strong, can satisfy general demand fully.To coat the better product of intensity in order further obtaining, can be designed to up-and-down state to the cross section external frame of internal layer, or to increase several grooves.
The double-deck section bar made from technique scheme can be applied aspect a lot, such as: the pole of bearch umbrella and skeleton; Bicycle tripod; Door-window section bar; Guardrail or the like.Can reach with mould Dai Mu, with the purpose of plastics for steel.
A lot of double-deck glass fibre reinforced plastics/plastic cement bimetallic tube is arranged in the market, its technological scheme is to increase one deck glass fibre reinforced plastics surrounding layer with winding process again in the outside of plastic cement pipe, this double-layer composite pipe is mainly used in the liquid material of requirement of withstand voltage and carries, structurally just in time opposite with bimetallic tube of the present invention, it is also different to strengthen purpose, belong to diverse technological scheme, particularly realize on the technology it being that diverse model is raised.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of fiber reinforced composite section bars of excellent combination property, reach with mould Dai Mu, to mould the purpose of Dai Gang.Described section bar is meant tubing, bar or profile shapes.
For solving the problems of the technologies described above, the double-deck fibre-reinforced polymer matrix composites section bar of the present invention, it is characterized in that: the internal layer of described section bar is made by fibre-reinforced polymer matrix composites, particularly the fibre-reinforced polymer matrix composites section bar that is made by pultrude process is made, skin is made by plastic material, particularly make, form the double layer construction form of plastic material clad composite material internal layer by thermoplastic.
Glass fibre, carbon fiber, aramid fibre, vegetable fiber can be as the reinforcing fiber of section bar of the present invention, and other fiber with similarity also can be as the reinforcing fiber of section bar of the present invention.Mixed fibre by two or more fiber blends also can be as the reinforcing fiber of section bar of the present invention.
In order to strengthen the combination force between the internal and external layer, can be designed to up-and-down state to the cross section external frame of internal layer, or increase several grooves, surrounding layer is then corresponding recessed or protruding.
The present invention is specially adapted to tubing, bar and the profile shapes of outer profile size between 10mm-300mm, and such section bar can be applied to the structural member of a lot of equipment and supplies.
For tubing, suitable size is: the internal layer wall thickness is between 2mm-100mm, and the wall thickness of surrounding layer is between 0.5mm-15mm.
For bar, suitable size is: external diameter or outer profile size are between 10mm-300mm, and the wall thickness of surrounding layer is between 0.5mm-15mm.
For profile shapes, suitable size is: outer profile size is between 10mm-300mm, and the internal layer wall thickness is between 1mm-20mm, and the surrounding layer wall thickness is between 0.5mm-10mm.Profile shapes commonly used has " U " section bar.
