Abstract
A three-dimensional reinforced fabric knitted with foam strips is composed of warp yarns (1), weft yarns (2), connecting yarns (3) and foam strips (4), and is characterized in that upper warp yarns (1) and upper weft yarns (2) are knitted to form an upper surface, lower warp yarns (1) and lower weft yarns (2) are knitted to form a lower surface, the upper and lower surfaces are connected with each other into a whole by connecting yarns (3), and foam strips (4) are knitted in the interlayer of the upper and lower surfaces. The foam strips (4) are knitted in the interlayer of the three-dimensional reinforced fabric to have a certain rigid support so that vacuum resin import composite process and resin transfer molding process can be adopted to improve the qualified rate, quality, accuracy and anti-fatigue and other properties of the reinforced composite material, and the foam strips are knitted to lead the fabric to have better sound and heat insulation performance.
Description
Technical field
The present invention relates to a kind of three-dimensional reinforced fabric of knitted with foam strips, particularly a kind of three-dimensional reinforced fabric that can adopt vacuum resin to import combination process and resin transfer molding technology.
Background technology
Along with deepening continuously of three-dimensional hollow layer connecting fabric research field, three-dimensional hollow layer connecting fabric is as the base cloth of three-dimensional reinforced composite, advantages such as its whole not stratified and high-strength light obtain the every profession and trade approval, have been applied to industries such as the energy, storage tank, boats and ships, communications and transportation and building.But its insulation heat-insulating property is poorer than foamed plastics sandwich, and because of three-dimensional hollow layer connecting fabric before not compound, hollow layer does not have the certain rigid skeleton to support, combination process can only adopt manual pasting forming process, there are a series of problems in manual pasting forming process, discharging exceeds standard as volatilizable organic matter (VOC), health effect to operating personnel is big, personnel are easily run off, many materials limitations are many, it is low to produce mouthful performance, resin waste and consumption are big etc., especially unstable product quality, the fiber of product and resin ratio, component thickness, layer material made speed, the uniformity of layer material etc. all is subjected to operating personnel's influence.
The vacuum resin introducing technology is the low-cost manufacturing technique that develops over nearly 20 years, is suitable for the manufacturing of large product especially, and its advantage has properties of product good, the yield rate height; Constant product quality, good reproducibility; Anti-fatigue performance improves, and can alleviate construction weight; The environment friendliness; The product good integrity; Reducing raw material uses; The goods precision is good etc.
Resin transfer molding technology is a kind of closed moulding technology, is characterized in making the goods of pleasing both parties; The shaping efficiency height; Free from environmental pollution, do not damage workers ' health; Reinforcing material can any direction lay, realizes pressing the reasonable lay reinforcing material of goods force-bearing situation easily; Raw material and energy resource consumption are few; The small investment of founding the factory, last detective etc.
Vacuum resin introducing technology and resin transfer molding technology are that base cloth itself has certain rigid backbone to support to the requirement of base cloth, and base cloth can not make the base cloth modification because of the pressurization of negative pressure after vacuumizing and mould, thereby influences stereoeffect, causes moulding bad.
Summary of the invention
The invention provides a kind of three-dimensional reinforced fabric of knitted with foam strips, whole not stratified property, high-strength light performance that three-dimensional hollow layer connecting fabric is promptly arranged, the certain rigid skeleton is arranged again, can realize that vacuum resin imports combination process and resin transfer molding technology, improves product quality stability.And after foam strip inweaves the intermediate layer, can improve the sound-insulating performance of material.
The technical solution adopted for the present invention to solve the technical problems is: this three-dimensional reinforced fabric, it mainly is made up of warp thread, weft yarn, connection yarn and foam strip, it is characterized in that, last warp thread and last weft yarn are woven into upper surface, following warp thread and following weft yarn are woven into lower surface, by connecting yarn that the connection of upper and lower surface is in aggregates again, be woven with foam strip in the hollow layer of upper surface and lower surface.
Described three-dimensional reinforced fabric, the raw material of warp thread, weft yarn, connection yarn can adopt one or more in the fortifying fibres such as glass fibre, carbon fiber, aramid fiber, high-strength high-modulus polyethylene.
Described three-dimensional reinforced fabric, foam strip are that cylinder is rectangular, and the thickness of three-dimensional reinforced fabric can be adjusted according to the thickness of foam strip, and the diameter of foam strip is between 1mm～20mm.
Described three-dimensional reinforced fabric, the raw material of foam strip can adopt a kind of among EVA, EPE or the PU.
The invention has the beneficial effects as follows: after foam strip inweaves the intermediate layer, make fabric that the certain rigid skeleton be arranged, so just can adopt vacuum resin to import combination process and resin transfer molding technology, improve performances such as reinforced composite yield rate, quality, precision and antifatigue, and inweaving of foam strip can make goods have better sound-insulating performance.

Description of reference numerals:
1 warp thread, 2 weft yarns, 3 connect yarn, 4 foam strips
The specific embodiment
Below in conjunction with drawings and the embodiments the present invention is described in further detail.
As shown in Figure 1, last warp thread 1 forms upper surface with last weft yarn 2 through braiding, and following warp thread 1 forms lower surface with following weft yarn 2 through braiding, connects yarn 3 and interts on upper and lower surface, connect upper and lower surface in aggregates, and the formation intermediate layer, this is three-dimensional hollow layer connecting fabric, its intermediate layer has only the yarn 3 of connection, be stressed slightly and just can be out of shape, so can not adopt vacuum resin to import combination process and resin transfer molding technology, and as shown in Figure 2, foam strip 4 just in time inweaves in the intermediate layer.Make three-dimensional reinforced fabric have the certain rigid skeleton, thereby can realize that vacuum resin imports combination process and resin transfer molding technology, compare with manual pasting forming process, improve performances such as reinforced composite yield rate, quality, precision and antifatigue greatly.
Three-dimensional reinforced fabric inweaves because of foam strip in the intermediate layer 4, has also improved the sound-insulating function of goods, and the thickness of three-dimensional reinforced fabric can be adjusted according to the thickness of foam strip 4.
