A lightweight fiber reinforced thermoplastic composite having an improved combination of flexural, impact, and heat distortion characteristics. The composite generally comprises a fiber reinforced thermoplastic core containing reinforcing fibers bonded together with a first thermoplastic resin in which the core has a first surface and a second surface and at least one first skin applied to the first surface. The first skin comprises one or more bi-directional continuous fiber tapes having a plurality of continuous fibers bonded together with one or more thermoplastic resins. The fibers in each first skin are arranged in a first principal direction and a second principal direction, with the fibers in each direction being aligned in a unidirectional orientation within the skin. The fiber reinforced composite of the invention includes embodiments wherein one or more tapes is utilized in which the bi-directional orientation of the continuous fiber tapes is present in at least one of the tapes, or is achieved through the use of two or more tapes having unidirectional continuous fibers. The invention is useful in the manufacture of automotive, rail, bus, marine, aerospace and construction articles in which the improved characteristics provide advantages over other materials utilized for such applications.
