Abstract
The utility model relates to a pull-extrusion protective cover. The pull-extrusion protective cover is characterized in that the profile of the pull-extrusion protective cover is 'Men' (men is a character, meaning a door)-shaped, arc chamfers are formed on two sides of the upper part of the pull-extrusion protective cover, and transition edges are formed on two sides of the lower part of the pull-extrusion protective cover; the profile of the pull-extrusion protective cover has a three-layer structure, namely including a glass fiber bundle, a glass fiber felt and glass fiber woven roving in sequence from inside to outside; the glass fiber woven roving has a crisscross netlike structure formed by warps and wefts which are fixedly connected with each other; and the glass fiber bundle, the glass fiber felt and the glass fiber woven roving are fixed through extrusion bonding. The weight of the glass fiber felt is 300g/m<2>, and the weight of the glass fiber woven roving is 200g/m<2>. The pull-extrusion protective cover is compact in structure, convenient and practical, is slightly affected by wind resistance, and can ensure the strength of a product in the longitudinal direction and effectively enhance the transverse strength of the product through material laying structure design.
Description
Technical field
The utility model relates to a kind of pulling-extruding slender product, and particularly a kind of pultrusion protective cover is mainly used in high ferro etc. and may bears on the thin-wall product of lateral stress.
Background technology
Today that current high-speed railway is fast-developing and resource is day by day deficient, high-performance composite materials are in railway systems application expansion day by day, and particularly thermosetting pultrusion product is replacing traditional steel products gradually with its excellent mechanical property.But, conventionally pultrusion product is only focused on longitudinal mechanical strength, has adopted a large amount of unidirectional continuous fibers to strengthen longitudinal strength, and the felt-cloth layer of product surface only plays styling, often ignore its lateral performance, particularly in some practical applications, may bear lateral stress thin-wall product.Laterally proof stress deficiency can cause the phenomenons such as product easy fracture, cracking, bending, has serious potential safety hazard.
Utility model content
The technical problem that the utility model solves is the above-mentioned defect that overcomes prior art, and a kind of pultrusion protective cover is provided.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of pultrusion protective cover, it is characterized in that pultrusion protective cover section is door type, both sides, top have circular arc chamfering, both sides, bottom have transition limit, pultrusion protective cover section is followed successively by glass fiber bundle, glass fibre felt-cloth, glass fibre woven roving three-decker from inside to outside, glass fibre woven roving forms network structure in length and breadth by the warp thread and the weft yarn that are fixedly connected with, between glass fiber bundle, glass fibre felt-cloth, glass fibre woven roving, is adhesively fixed by extruding.Glass fibre woven roving weft yams can be pultrusion product cross-protection is provided, and strengthens its transverse mechanical performance, reaches the object that stops product Transverse Cracks.
The grammes per square metre of glass fibre felt-cloth described in the utility model is 300g/m
2, the grammes per square metre of described glass fibre woven roving is 200g/m
2.
The utility model is for the not foot phenomenon of lateral stress of pultrusion protective cover product, the utility model designs a kind of glass fibre felt-cloth and the compound paving mode of paving altogether of glass fibre woven roving, significantly improve transverse mechanical intensity, effectively solve the laterally phenomenon such as easy to crack, fracture of pultrusion product.
The utility model is simple for structure, convenient and practical, and windage effect is little, by material laying structural design, can, in ensureing product longitudinal direction intensity, effectively strengthen its transverse strength.
Brief description of the drawings
Fig. 1 is the production process schematic diagram of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment pultrusion protective cover.
Fig. 3 is sectional structural map local shown in Fig. 2 elliptic arc.
In figure: 1-the present embodiment product, 2-mould, 3-preforming tool, 4-glass fibre woven roving, 5-glass fibre felt-cloth, 6-resin paste, 7-glass fiber bundle, 8-collection yarn device.
Detailed description of the invention
Referring to Fig. 1～Fig. 3, the utility model embodiment pultrusion protective cover adopts continuous Non-twisting glass fibre bundle 7 to arrange through collection yarn device 8, and floods through resin paste 6 in guiding dipping tank, then draws to preforming tool 3.Preforming tool 3 first paragraphs add 300g/m in glass fiber bundle 7 outsides
2glass fibre felt-cloth 5, preforming tool 3 second segments further add one deck 200g/m in glass fibre felt-cloth 5 outsides
2glass fibre woven roving 4, three-decker fabric together enters mould 2.In the squeezing action of preforming tool 3 and mould 2, the resin paste 6 that glass fiber bundle 7 floods can be extruded, and is absorbed by outer field glass fibre felt-cloth 5 and glass fibre woven roving 4.Through hot setting moulding, under the pulling force of draw-gear and mould and squeezing action, obtain respective design the present embodiment product.
In Fig. 2, the present embodiment section is door type, and both sides, top have circular arc chamfering 9, reduces windage effect, and both sides, bottom have transition limit 10, facilitates being connected of the present embodiment and high ferro compartment or other parts.
The present embodiment section is made up of three parts through amplifying mainly, is followed successively by from inside to outside glass fiber bundle 7, glass fibre felt-cloth 5, glass fibre woven roving 4, forms orderly, the composite construction of " fiberglass layer-felt-cloth layer-grid layer of cloth ".Glass fibre woven roving 4 has network structure in length and breadth, significantly improves the present embodiment transverse mechanical intensity.
It is the main resin paste of making that the present embodiment resin paste can be selected the unsaturated polyester (UP), epoxy resin, vinylite of prior art etc.
The equivalent transformation of every technical solutions of the utility model and technical characterictic or combination, all should think and fall into protection domain of the present utility model.
