A fiber-reinforced plastic bar comprises a core and a surface member, the core comprises a high strength continuous fiber and a matrix resin, and the surface member comprises a polypropylene fiber. This fiber-reinforced plastic bar does not undergo degradation even when mortar, concrete, etc, are cured in an autoclave.

Fiber-reinforced plastic bar and production method thereof

A process is disclosed for the preparation of a network article of a leno cloth fixed with a resin. The leno cloth is impregnated with the resin and the resin is solidified while tension is applied in the direction of the weft of the cloth.

Process for the preparation of a network article

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.
