Abstract:
A composite sheet having a longitudinal axis, said composite sheet comprising:a base layer having upper and lower surfaces; a surface layer comprised of continuous fibers extending parallel to said longitudinal axis and having a predetermined width defined between transversely opposite side edges of said surface layer; and a plurality of attaching lines which attach the continuous fibers to at least one of the upper and lower surfaces of the base layer, said plurality of attaching lines extending in a direction intersecting said longitudinal axis, said attaching lines comprising a plurality of first attaching lines that extend from one of said opposite side edges and terminate in a vicinity of said longitudinal axis at intervals in a one half region of said surface layer defined on one side of said longitudinal axis so as to bisect said width of said surface layer and a plurality of second attaching lines that extend from the other one of said opposite side edges and terminate in a vicinity of said longitudinal axis also at intervals in another half region of said surface layer on another side of said longitudinal axis, said first and second attaching lines extending obliquely to said longitudinal axis so as to intersect each other on extensions of said first and second attaching lines toward said longitudinal axis.
