Abstract:
Provided is a composite laminate having excellent releasability from a mold during a production process, excellent surface appearance (surface smoothness) and mechano-physical properties, and excellent workability and coating adhesion. A composite laminate 1 includes an A layer 2 and a B layer 3, wherein the A layer 2 is provided directly or indirectly on one or both sides of the B layer 3, the A layer 2 contains reinforcing fibers (a1) with an average fiber length of 1 μm to 300 μm, spherical particles (a11) with a volume mean particle diameter of 0.01 μm to 100 μm, and a thermoplastic resin (a2), and the B layer 3 contains reinforcing fibers (b1) with an average fiber length of 1 mm or more and a thermoplastic resin (b2).
