Title: Woven fabric of composite material

Description:
FIELD OF THE INVENTION 
   The present invention relates to woven fabrics, more particularly to a woven fabric of composite material having glittery colors and better light reflection. 
   BACKGROUND OF THE INVENTION 
   Woven fabrics of composite material are used for covering the surface of an object so as to reinforce the structure of the object. The object can be rackets of various types, golf clubs, bicycle parts, materials for making shoes, etc. 
   Referring to  FIG. 3 , a woven fabric of composite material of the prior art comprises a transverse thread system  30  and a longitudinal thread system  40 , which are woven together in an interlaced fashion. In the texture, one transverse thread is passed around all of the longitudinal threads in a perpendicular direction in a waved way, namely, the transverse thread passing over a longitudinal thread and passing under the next longitudinal thread. An adjacent transverse thread is passed around the longitudinal threads in the same way, but the up locations and the down locations are flipped. 
   However, the color of the woven fabrics of composite material of the prior art are of single color, which lack visual appeals. To decorate the fabrics, colors are applied on the surfaces of the fabrics by printing and spray painting, which will increase the production cost by using extra labors for the painting job and paints. Further, the paint on a fabric thus made is easy to fall off due to frictional contact with other objects. Even a fabric made of para-Aramid fibers and glass fibers has the above disadvantages. 
   Motivated by improving the above disadvantages, the inventor invents the present invention for providing an improved woven fabric of composite material. 
   SUMMARY OF THE INVENTION 
   Accordingly, the primary objective of the present invention is to provide a woven fabric of composite material having a reinforced structure, bright colors and a light-reflecting effect. 
   The secondary objective of the present invention is to provide a woven fabric of composite material that is easy to manufacture and suitable for mass production. 
   To achieve the above objectives, a woven fabric of composite material, according to the present invention comprises a longitudinal thread system, a transverse thread system and a multitude of glittery threads. The transverse thread system is woven together with the longitudinal thread system in an interlaced fashion. The glittery threads are woven into at least one of the longitudinal thread system and the transverse thread system, whereby a woven fabric thus made will have bright colors and a light reflecting effect. Further, the threads of the longitudinal thread system and the transverse thread system are selected from para-Aramid fibers and glass fibers. 
   The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings. 

   
     BRIEF DESCRIPTION OF THE DRAWINGS 
       FIG. 1  shows the structure of the present invention as a woven fabric of composite material. 
       FIG. 2  is a local enlarged view of the woven fabric of composite material in  FIG. 1 . 
       FIG. 3  shows the structure of a woven fabric made of carbon fibers. 
   

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Referring to  FIGS. 1 and 2 , a woven fabric of composite material comprises a transverse thread system  10  and a longitudinal thread system  20 . The transverse thread system  10  and the longitudinal thread system  20  are woven together in an interlaced form, as shown in  FIG. 1 . The transverse thread system  10  and the longitudinal thread system  20  are para-Aramid fibers or glass fibers, at least one of which systems is provided with a multitude of glittery threads A, colored plastic threads or threads having better light reflection, as shown in  FIG. 2 . 
   Therefore, as the transverse thread system  10  and the longitudinal thread system  20  are being woven together, glittery threads A are added to either the transverse thread system  10  or the longitudinal thread system  20 , so as to reinforce the structure of the fabric and bright up the fabric by providing various light reflecting patterns of visual appeal, as shown in  FIG. 2 . 
   Besides the above-mentioned preferred embodiment, the transverse thread system  10  and the longitudinal thread system  20  can be of various combinations so as to provide the same effects. 
   In a second preferred embodiment, carbon fibers are woven into the transverse thread system  10  and the longitudinal thread system  20  made of para-Aramid fibers or glass fibers. 
   In a third preferred embodiment, the transverse thread system  10  and the longitudinal thread system  20  are made of carbon fibers or para-Aramid fibers. 
   In a fourth preferred embodiment, the transverse thread system  10  and the longitudinal thread system  20  are made of carbon fibers or glass fibers. 
   In a fifth preferred embodiment, the transverse thread system  10  and the longitudinal thread system  20  are made of glass fibers. 
   In a sixth preferred embodiment, the transverse thread system  10  and the longitudinal thread system  20  are made of para-Aramid fibers. 
   The present invention is thus described, and it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
