Embodiment
Below in conjunction with drawings and Examples technological scheme of the present invention is explained in detail.
FRP is the abbreviation of Fiber Reinforced polymer (fibre reinforced materials).
As shown in Figures 1 to 4, the invention provides a kind of FRP Material cladding Stainless Steel Tube, comprise Stainless Steel Tube 20, be fastened on the FRP material of described Stainless Steel Tube 20 outer surfaces.In the situation that guarantees FRP Material cladding Stainless Steel Tube property indices, effectively reduce the wall thickness of Stainless Steel Tube 20, reduce cost of material and material weight; And adopt the FRP material to meet environmental protection, conservation-minded society's growth requirement.The FRP Material cladding Stainless Steel Tube that the present invention produces, the FRP material is that smooth shape makes between the tubing and can connect by insertion, has solved well the narrow limitation of pipe applications.
FRP Material cladding Stainless Steel Tube is that Stainless Steel Tube 20 places this FRP material middle by 4 pultrusions are pre-formed as cylindrical FRP material at the stainless steel outer surface through buncher with reinforcing fiber and resin compound.As depicted in figs. 1 and 2, described FRP material can be unidirectional fiber material 10.Also can be as shown in Figure 3 and Figure 4, described FRP material comprises unidirectional fiber material 10 and multidirectional fiber woven material 11, described multidirectional fiber woven material 11 is between described Stainless Steel Tube and described unidirectional fiber material 10.Described multidirectional fiber woven material 11 is fabric or twines the two-way fibrous structure layer that forms.Unidirectional fiber material 10 of the present invention and multidirectional fiber woven material 11 are the definition of macroshape, and unidirectional fiber material 10 finger macroshapes are characterized by the material of same direction; Multidirectional fiber woven material 11 finger macroshapes are characterized by at least material of the fibrage more than the both direction.Both all are that unidirectional fibre consists of on microcosmic for unidirectional fiber material 10 and multidirectional fiber woven material 11.Wherein unidirectional fiber material 10 provides radial strength for FRP Material cladding Stainless Steel Tube, and multidirectional fiber woven material 11 guarantees the hoop mechanical property of FRP Material cladding Stainless Steel Tube.
Described Stainless Steel Tube 20 thickness 〉=0.2mm, the thickness that can select described Stainless Steel Tube 20 is 0.5mm, preferably the thickness of Stainless Steel Tube 20 is 0.2mm; Thickness 〉=the 1mm of described FRP material, preferably the thickness of described FRP material is 2~3mm.The present invention adopts 0.2mm thick Stainless Steel Tube 20 to support as inwall, Stainless Steel Tube 20 guarantees its corrosion resistance, the performances such as internal pressure-resistant change consumption, thickness or the material of outsourcing FRP material by the product specification requirement, can effectively guarantee under the condition of the corrosion resistance of tubing and every mechanical property requirements, reduce cost of material and material weight, provide cost advantage and weight advantage for product uses.
Described unidirectional fiber material 10 comprises reinforcing fiber and resin.The weight percentage of reinforcing fiber is 75%, and the weight percentage of resin is 25%.Described reinforcing fiber is any one in glass fibre, aramid fibre, polyvinyl fiber, basalt fibre, carbon fiber, ramee, flax fiber, the jute fiber.Described resin is any one in the unsaturated resin, epoxy resin, vinyl ester resins in the thermosetting resin.
The present invention take the FRP material be unidirectional fiber material 10 as example, wherein glass fibre is reinforcing fiber, take vinyl ester resins as matrix resin, gets FRP Material cladding Stainless Steel Tube by pultrusion heat cure moulding process preparation.
Wherein, the vinyl ester resins glue is to be mixed by vinyl ester resins, coupling agent, benzoyl peroxide, peroxidized t-butyl perbenzoate, vinyl benzene, filler and mill base; Wherein, get parts by weight and be 100 parts vinyl ester resins, at the parts by weight that add other each component be: coupling agent 0.5-3.0 part, benzoyl peroxide 0.2-1.0 part, peroxidized t-butyl perbenzoate 0.8-1.8 part, vinyl benzene 2-10 part, filler 3-10 part and mill base 0.5-1.5 part.
FRP Material cladding Stainless Steel Tube mainly prepares moulding process can be divided into following preparation section:
Send the yarn → impregnation → collection of filaments → Stainless Steel Tube to insert → pre-shaping → traction → solidifying → cutting
The preparation process of FRP Material cladding Stainless Steel Tube of the present invention adopts traditional pultrusion heat cure moulding process, and Plant reconstruction plant modernization requires little, can produce at existing pultrusion Wiring apparatus, and application prospect is extensive.
Specifically describe forming preparation process of the present invention below in conjunction with accompanying drawing 5:
(1) described glass fibre places on the fiber creel 1, draws several the hole share split tractions of entrying by threading board 2, under the effect of tractive force, enters resin storage tank 3 and carries out impregnation, and glue is above-mentioned vinyl ester resins glue;
(2) glass fibre behind the impregnation is extruded fiber resin adhesive liquid more than needed by buncher 4 and pre-shaping device 5 successively under the effect of tractive force, Stainless Steel Tube 20 is placed to the middle of glass fibre simultaneously, Stainless Steel Tube 20 with the glass fibre behind the impregnation by tractor toward front haulage, under the effect of the extrusion die of pre-shaping device 5, glass fibre and resin blend thing are in the braiding of Stainless Steel Tube 20 outer surfaces and tentatively be shaped to columniform FRP material shape;
(3) preformed cylindrical FRP material through shaping die and winding head 6, is further extruded resin adhesive liquid more than needed again;
(4) the FRP Material cladding Stainless Steel Tube of process above-mentioned steps is under the effect of tractive force, enter the device 7 that is heating and curing, shaping die and winding head 6 and the device 7 that is heating and curing are provided with heating plate, the FRP material generation curing reaction that is heated under the temperature that sets, finally obtaining configuration of surface is the FRP Material cladding Stainless Steel Tube of smooth shape.
(5) last FRP Material cladding Stainless Steel Tube draws to cutting device 9 through traction gear 8 and cuts into satisfactory FRP composite stainless steel pipe finished product.
When another embodiment of the present invention comprises unidirectional fiber material 10 and multidirectional fiber woven material 11 take the FRP material as example, wherein glass fibre is reinforcing fiber, take vinyl ester resins as matrix resin, multidirectional fiber woven material 11 adopts the two-way fibrous structure layer that forms through twining, and gets FRP Material cladding Stainless Steel Tube by the preparation of pultrusion heat cure moulding process.
Preparation process is basic identical with last preparation process, just when (2) step Stainless Steel Tube 20 is placed to the middle of glass fibre, Stainless Steel Tube 20 outer surfaces of this moment are tied with two-way fibrous structure layer, and namely Stainless Steel Tube 20 all is to have twined multidirectional fiber woven material 11 just to enter (2) step.
Above content is the further description of the present invention being done in conjunction with concrete preferred implementation, can not assert that implementation of the present invention is only limited to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
