  • Impregnated leno fabric and reinforced inorganic matrix article
    Patent number: 5110656
    Abstract: A network article comprises reinforcing fiber fixed with a resin, in which the weft is almost straight and, preferably, the warp is also almost straight. To attain this, the warp consists of at least two kinds of yarns having different rigidities, and the lower rigidity yarn wreathes with higher rigidity yarn. Alternatively, a leno cloth is drawn in the weft direction to straighten the weft and then the resin is solidified under tension. The network article and a shaped inorganic product reinforced therewith exhibit higher tensile strength than those of the prior art.
