PURPOSE:To substantially improve tensile strength relative to the direction of a wall thickness and, therefore, render interlayer separation hard to occur by making a number of rhombus-shaped whiskers disperse in the layer of glass fibers. CONSTITUTION:A number of rhombus-shaped whiskers 6 are dispersed in the wall thickness of an article 4 by allowing them to thrust glass fibers 5. The whiskers 6 are in a shape of a tetrapod, for example, some of whiskers consisting of zinc oxide or potassium titanate become such configurations in the growth of its crystal. |
