Abstract
The present invention is the weaving process of stitching weft-knitted alternative fabric with surface warp inserting and weft inserting structure of certain thickness in a weft knitting machine. In a weft knitting machine with two opposite needle bed, the needles in both the front needle bed and the back needle bed feed the yarns essential for the flat stitch structure while feeding the yarns essential for the ribbing structure, so as to form the stitching alternative structure. The needles of the front and the back needle beds form the front sheet and the back sheet of the fabric, and provide the warp inserting and weft inserting yarns while providing the yarns for the flat stitch structure and the yarns for the ribbing structure, so as to form the warp inserting and weft inserting of the fabric. The woven fabric is suitable for use as the strengthening body for RTM integrally formed composite material.
Description
Affiliated technical field
The present invention relates to the weaving method that a kind of knitted composite material strengthens the body and function fabric, especially a kind of weaving method that has the stitching weft-knitted alternative fabric of certain thickness top layer laying-in inlaid thread structure on the double side weft knitting knitting machine, the fabric that is woven into is suitable as composite material reinforcement body.
Background technology
Textile material development in recent years as composite material reinforcement body is the three-dimension integrally structure, and various countries have all given increasing research and input to this.The three dimensional fabric composite reaches interlaminar strength in improving layer and the anti-aspect of performance that damages has good performance, and it has overcome intrinsic shortcomings such as the easy layering of two-dimensional structure composite prefabricated component, thereby good application and development prospect are arranged.
Further, in the three-dimension integrally structure, the fabric of cabinet-type is because have not stratified, light weight, specific strength height, specific modulus height, shock resistance, anti-ablation, intensity advantages of higher, and particularity in weaving and certain degree of difficulty, becomes an inevitable direction of present research.
At present, be well known that, knitted fabric is compared with other fabrics, structurally exist the following deficiency as composite material reinforcement body: the yarn in the knitted fabric is difficult to become the straight latitude state of straight warp of the high-strength and high-modulus that can make full use of high-performance fiber always, because the knitting process that exactly yarn is bent to coil and wears mutually in definition.
Summary of the invention
For overcome above-mentioned knitted fabric when the composite in structure and the deficiency of weaving, the invention provides the weaving method that a kind of knit spacer type strengthens the body and function fabric, especially a kind of have the certain intervals thickness and a lopping type weft-knitted fabric weaving method of top layer laying-in inlaid thread on the double side weft knitting knitting machine.
The inventive method is, on weft machine with two opposed needle-bars, carry out the braiding of the lopping type spacer structure integral thickness fabric of top layer laying-in inlaid thread: the knitting needle of front and back needle-bar is when pad is fed the required yarn of flat needle structure separately, also common pad is fed the required yarn of rib-loop structure, and this just can form lopping type weft knitting institutional framework at interval; The front and back sheet fabric that the knitting needle of front and back needle-bar forms structurally except being woven with the required yarn of flat needle structure and rib-loop structure, also being knitted in each sheet of front and back sheet and is applied into laying-in yarn and weft-inserted yams, forms top layer laying-in inlaid thread structure.
The invention has the beneficial effects as follows, can the double side weft knitting knitting machine with the fiber of high-performance or high rigidity or yarn weave have certain thickness, the stitching weft-knitted alternative fabric of top layer laying-in inlaid thread.This structure because the spacer structure of its fabric has lower fiber volume fraction and is loop construction on the formation method organizing, thereby has good mouldability, permeability when the composite material reinforcement body; Because its laying-in inlaid thread structure can make full use of the high-strength and high-modulus of high-performance fiber, thereby also has excellent mechanical property.

1. preceding needle-bar plain weave yarns, 2. back needle-bar plain weave yarn, 3. rib-loop yarn among the figure, 4. lopping type weft knitting is institutional framework at interval, 5. fabric rear panel top layer laying-in yarn, 6. fabric rear panel top layer stuffer weft, 7. fabric anter top layer stuffer weft, 8. fabric anter top layer laying-in yarn, 9. fabric intermediate layer stuffer weft, 10. front needle bed knitting needle, 11. back needle-bed knitting needles, 12. the fabric anter, 13. fabric rear panels.
The specific embodiment
Fig. 6 is an example of the present invention, for the intermediate layer of stitching weft-knitted alternative fabric promptly before and after between the sheet fabric at interval in, also folder is lined with weft-inserted yams.
Fig. 6 is illustrated on the weft machine with two opposed needle-bars, has the braiding of certain thickness stitching weft-knitted alternative fabric top layer laying-in inlaid thread structure:
In conjunction with pad yarn weaving mode shown in Figure 2, the knitting needle 10,11 of front and back needle-bar is when pad is fed the required yarn 1,2 of flat needle structure separately, also common pad is fed the required yarn 3 of rib-loop structure, and this has just formed lopping type weft knitting institutional framework 4 at interval in the mode of stack, as shown in Figure 1;
In conjunction with the schematic diagram of the pad yarn weaving of laying-in inlaid thread structure chart shown in Figure 3 and laying-in inlaid thread structure shown in Figure 4, the anter fabric 12 that the knitting needle 10 of preceding needle-bar forms structurally except yarn 1,3, is also knitted and is applied into laying-in yarn 8 and weft-inserted yams 7; The rear panel fabric 13 that the knitting needle 11 of back needle-bar forms structurally except yarn 2,3, is also knitted and is applied into laying-in yarn 5 and weft-inserted yams 6;
So, Fig. 6 is the comprehensive of Fig. 2 and Fig. 4, the result has just formed the weft-knitted space fabric of lopping type top layer laying-in inlaid thread structure: the front and back sheet fabric 12,13 that the knitting needle 10,11 of front and back needle-bar forms, structurally except being woven with the required yarn of flat needle structure and rib- loop structure 1,2,3, also knit in front and back sheet 12,13 each sheet and apply into laying-in yarn 5,8 and weft-inserted yams 6,7, the complete organization chart of anter 12 or rear panel 13 is expressed as Fig. 5.As shown in Figure 6, fabric between front and back sheet 12,13 at interval in, also folder is lined with weft-inserted yams 9, with further enhancing with add heavy weave.
