Abstract
The invention provides a foam filled stereoscopic reinforced material. Three-dimensional hollow laminating fabric (1) is taken as composite material base fabric, the base fabric is mainly formed by weaving warp (3), weft (4) and connecting yarn (5) by an integrated machine, the hollow layer of the three-dimensional hollow laminating fabric (1) is filled with foam plastic (2), expanded foam plastic is utilized to straighten the connecting yarn (5) in the hollow layer, so that the material can stand well and form a foam filled stereoscopic reinforced material with certain rigidity framed, thus vacuum resin introduction technology can be adopted in resin compounding, yield, quality, precision and antifatigue properties of composite material are improved, and meanwhile environment and health of workers are protected. The invention adopts three-dimensional hollow laminating fabric as base fabric and filled foam plastic, so that the reinforced material after resin compounding can not be peeled or layered in long term use and has the characteristics of heat preservation and heat insulation.
Description
Technical field
The present invention relates to a kind of foam-filled stereoscopic reinforced material, particularly a kind of stereoscopic reinforced material that can adopt vacuum resin to import combination process.
Background technology
The insulation heat-insulating property of foamed plastics sandwich is best in all sandwiches, maximum in the market is to adopt prefabricated core adhesive moulding technique, promptly make reinforcing material covering (surface layer) and foamed plastics sandwich layer respectively, select cement for use according to serviceability temperature, pressure, solvent, with cement covering and sandwich layer are binded moulding then.But surface layer and interlayer were easily peeled off when the shortcoming of this technology maximum just was to use, and formed layering.Three-dimensional hollow layer connecting fabric is the one weaving, thus with resin molding compound after, globality is very good, lamination can not appear peeling off in permanent use, but this material sound insulation heat-insulating property is poorer than the foam core material, and, can only adopt manual pasting forming process and resin molding compound at present.The shortcoming of manual pasting forming process is a unstable product quality, and the fiber of properties of product, product and resin ratio, component thickness, manufacturing speed, uniformity etc. all are 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.But the vacuum resin introducing technology is that base cloth itself has certain rigid backbone to the requirement of base cloth, and the present invention adopts foam-filled stereoscopic reinforced material, can not make the base cloth distortion because of the negative pressure after vacuumizing, thereby influence stereoeffect, causes moulding bad.
Summary of the invention
The invention provides a kind of foam-filled stereoscopic reinforced material, earlier charge into foamed plastics in the hollow layer of three-dimensional hollow layer connecting fabric, fabric is fully stood up, material has the certain rigid skeleton, can realize the vacuum resin introducing technology, improve performance of composites.The height insulation heat-insulating property of the existing foamed plastics sandwich of the present invention lamination can not occur, and can adopt vacuum resin to import combination process in permanent the use, improve performances such as reinforced composite yield rate, quality, precision and antifatigue.
The technical solution adopted for the present invention to solve the technical problems is: filled and process material in the hollow layer of three-dimensional hollow layer connecting fabric, and utilize the foamed plastics that expands that the connection yarn of flexing in the hollow layer is stood up, fabric has the certain rigid skeleton.
Described three-dimensional hollow layer connecting fabric, mainly by warp thread, weft yarn be connected yarn and form, it is characterized in that: fabric can form through woven weaving, also can form through weave woven, last warp thread and last weft yarn are woven into upper surface, following warp thread and following weft yarn are woven into lower surface, and by connecting yarn that the connection of upper and lower surface is in aggregates again, fabric thickness can be between 3mm～40mm.
Described three-dimensional reinforced fiber, it is characterized in that: 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, and foamed material can adopt a kind of in the plastic foam materials such as EVA, EPE, PU.
The invention has the beneficial effects as follows: in foamed plastics charges into the hollow layer of three-dimensional hollow layer connecting fabric, connection yarn in the fabric hollow layer is stood up because of the expansion of foamed plastics, formation has the stereoscopic reinforced material of certain rigid backbone, like this, resin compounded technology just can adopt vacuum resin to import combination process, improve performances such as reinforced composite yield rate, quality, precision and antifatigue, and material is a base cloth because of adopting three-dimensional hollow layer connecting fabric, after charging into foamed plastics, possesses the adiabatic premium properties of the not stratified and high insulation of prolonged use.

Description of reference numerals:
1 three-dimensional hollow layer connecting fabric, 2 foamed plastics, 3 warp thread, 4 weft yarns, 5 connect yarn
The specific embodiment
Below in conjunction with drawings and the embodiments the present invention is described in further detail.
As shown in Figure 1, three-dimensional hollow layer connecting fabric 1 is to form upper surface by last warp thread 3 and last weft yarn 4 through braiding, following warp thread 3 forms lower surface with following weft yarn 4 through braiding, connecting yarn 5 interts on upper and lower surface, the connection of upper and lower surface is in aggregates, and form the intermediate layer, its intermediate layer has only the yarn 5 of connection, be stressed slightly and just can be out of shape, so can not adopt vacuum resin to import combination process.
When in the intermediate layer of fabric 1, charging into foamed plastics 2 (as shown in Figure 2), the foamed plastics that the connection yarn 5 of flexing will be inflated is stretching, thereby well stand up, form a kind of foam-filled stereoscopic reinforced material with rigid backbone, thereby can realize that vacuum resin imports combination process, compare with manual pasting forming process, improve performances such as reinforced composite yield rate, quality, precision and antifatigue greatly.And material is base cloth because of adopting three-dimensional hollow layer connecting fabric, charge into foamed plastics after, possess the adiabatic premium properties of the not stratified and high insulation of prolonged use.
