Title:
COVERING MATERIAL FOR REINFORCEMENT HAVING ELASTICITY AND REINFORCING METHOD USING THE SAME
Document Type and Number:
WIPO Patent Application WO/1999/036607
Kind Code:
A1
Abstract:
As a covering material for reinforcing an article made of a metal or a resin attached on the surface to be reinforced, wherein fibers are arranged to orientate along the direction intended for reinforcement, use is made of a knitted fabric which is manufactured by means of a knitting machine having an inserting mechanism which can be used for knitting together, in the form of a straight line, a reinforcing fiber such as a carbon fiber, as a yarn to be inserted, over the whole width or length in respective directions and manufactured using an elastic yarn as a looped yarn, or a woven fabric which is manufactured using a reinforcing yarn and an elastic yarn as the warp and the weft, respectively, wherein the fabric is manufactured in a way such that fibers for reinforcement mentioned above are positioned close to the article to be covered by the extending and shrinking force of the elastic yarn. Examples of the above mentioned fiber for reinforcement include fiber filaments bundled into a form of a flat tape or a form having varying thickness or width, and a tape or cord manufactured by lining up fiber filaments on a surface of a sheet followed by fixing and then cutting them. The use of this covering material for reinforcement permits reinforcing fibers to closely contact with ease with an article having various curved surfaces. Further, by fixing them using a matrix resin or the like, such an article can be reinforced evenly.
