ABSTRACT:
A paper-like product composed of staple fibers oriented substantially in a certain specific direction is provided, wherein the orientation degree of the constituent staple fibers, expressed by the following formula: ##EQU1## is at least 50%. A prepreg is formed by impregnating the paper-like product with a matrix resin. Composite prepregs are formed by laminating a plurality of such prepregs or such a prepreg with a prepreg composed of continuous filaments, in a manner such that the orientation directions of fibers in the prepregs intersect one another. The paper-like product is prepared by scattering a liquid dispersion of staple fibers in the horizontal direction by a centrifugal force, and collecting the scattered staple fibers in the form of a web on a collecting surface continuously moving in the vertical direction.
