Abstract
The utility model discloses a multi-axial stitch knitting felt. The multi-axial stitch knitting felt comprises warp-wise fiberglass rough yarns and weft-wise fiberglass rough yarns which are connected by adopting the stitch knitting structure. The multi-axial stitch knitting felt can be that three layers are mutually superposed and are connected by adopting the chain knitting structure after the warp-wise fiberglass rough yarns and the weft-wise fiberglass rough yarns are connected by adopting the stitch knitting structure. The provided multi-axial stitch knitting felt is light in weight with both intensity and thickness; by utilizing the distinctive properties of high intensity, high fiber content and high thickness, the multi-axial stitch knitting felt ideally solves the problems that finished products are heavy and thin; moreover, the multi-axial stitch knitting felt can completely exert the reinforcing effect of fibers on specific directions; therefore, the multi-axial stitch knitting felt is a novel multi-axial reinforcing material which cannot be curled and has multi-layer structures.
Description
Technical field
The utility model relates to a kind of construction material, and particularly a kind of multiaxis of rail transport, civil engineering, pipe container or the like industry that is widely used in is to the loop bonding felt.
Background technology
The traditional product body layer of prior art is based on fibre glass roving, being 0 °, 90 ° directions by warp-wise fibre glass roving, broadwise fibre glass roving interweaves, re-use glass chopped strand mats, be layering and form, manufactured goods are heavy and thin, do not reach the existing intensity of expection, thickness is arranged again, and the effect that alleviates of own wt.In conjunction with no any medium, structure is tight through, weft yarn for traditional product, and resin impregnated is poor in the product use, and resin flows speed differs, mutual superposition layer by layer, layer and layer between the space differ, cause product thickness lack of homogeneity, resin is many, and is thick; Resin is few, and is thin.Show that mainly the manufactured goods thickness differs, fiber content differs, cause manufactured goods intensity to differ, every layer mass area ratio difference, the shop layer is many more, causes population unit's area quality difference to become aggravation to increase, and needs to reduce the shop layer.
Summary of the invention
The purpose of this utility model is a kind of existing intensity that provides for the deficiency that solves above-mentioned technology, and thickness is arranged again, and the light multiaxis of own wt is to the loop bonding felt.
In order to achieve the above object, the designed multiaxis of the utility model is to the loop bonding felt, it comprises warp-wise fibre glass roving and broadwise fibre glass roving, the warp-wise fibre glass roving is connected by the loop bonding structure with the broadwise fibre glass roving, and warp-wise fibre glass roving and broadwise fibre glass roving can be 0 °, 90 ° direction stacks.Multiaxis can be to be connected back three layer mutual superposition with the broadwise fibre glass roving by the loop bonding structure by the warp-wise fibre glass roving to the loop bonding felt, connects by chain woollen yarn knitting structure.The warp-wise fibre glass roving uses the terylene thread loop bonding to be connected with the broadwise fibre glass roving, and its loop bonding mode is through compiling.The three stacked chain woollen yarn knitting structures that add are for using per 10 centimetres of seam 7 pins of fiberglass yarn.
The resulting multiaxis of the utility model is to the loop bonding felt, intensity height, fiber content height.Multiaxis thickness is arranged again, and own wt is light to the existing intensity of loop bonding felt.It has utilized multiaxis to the peculiar performance of loop bonding felt, and intensity height, fiber content height, thickness are thick, and very desirable solution the heavy and thin problems of manufactured goods; The traditional product stack pile uses glass fabric, glass chopped strand mats shop layer to reach 8 layers down, just can reach 3.3 millimeters of thickness.And this product once to spread layer be that thickness has reached 3.3 millimeters, reduced shop layer on year-on-year basis down 7 times, thickness is ideal very.Because multiaxis is considered in forming process to the loop bonding felt, does not influence resin, thereby use fiberglass yarn to carry out loop bonding, and density reduce, and has accelerated resin flow.Multiaxis can be given full play to the enhancing effect of fiber on specific direction to the loop bonding felt, and it is a kind ofly not curl, have multiaxis to the novel enhanced material of sandwich construction.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
As shown in Figure 1, the described multiaxis of present embodiment is to the loop bonding felt, and it comprises warp-wise fibre glass roving 1 and broadwise fibre glass roving 2, and warp-wise fibre glass roving 1 is connected by the loop bonding structure with broadwise fibre glass roving 2.Warp-wise fibre glass roving 1 and broadwise fibre glass roving 2 are 0 °, 90 ° direction stacks, use terylene thread 3 by connecting through the volume mode.
Embodiment 2
As shown in Figure 2, the described multiaxis of present embodiment is to the loop bonding felt, and its described multiaxis is to be connected back three layer mutual superposition with broadwise fibre glass roving 2 by the loop bonding structure by warp-wise fibre glass roving 1 to the loop bonding felt, connects by chain woollen yarn knitting structure.The chain woollen yarn knitting structure of three layers of mutual superposition connects for using fiberglass yarn 4 per 10 centimetres of seam 7 pins.Use fiberglass yarn 4 to carry out loop bonding, thereby density reduce, and has accelerated resin flow by chain volume mode.Its multiaxis can be given full play to the enhancing effect of fiber on specific direction to the structure of loop bonding felt, and it is a kind ofly not curl, have multiaxis to the novel enhanced material of sandwich construction.Multiaxis is rational proportion between each layer of loop bonding felt, arrange by specific direction, arrange as follows in order for every layer: 0 ° 90 ° 0 ° 90 ° 0 ° 90 °, this arrangement can make the docile property of giving full play between layer and the layer each other, has increased the docile property of staple fiber and fiber contact-making surface.By glass fiber yarn 4 loop bondings, be added on fixingly, thereby use 10 centimetres of seam 7 pins, use this stitch can avoid shortcomings such as product is tight, close, thick, real, make product accomplish a little combination, avoid the resin flows that is unfavorable for that contact because of face causes.It is loose that this production technology has reached the maintenance product structure, reaches thickness requirement, specification requirements such as the stretching resistance intensity of warp, broadwise, good uniformity.
