Provided are acoustic articles having a porous layer (102,104,106) placed in contact with a heterogeneous filler comprising porous carbon and having an average surface area of from 0.1 m.sup.2/g to 10,000 m.sup.2/g. The acoustic articles can have a flow resistance of from 10 MKS Rayls to 5000 MKS Rayls. Optionally, the porous layer includes a non-woven fibrous layer or a perforated film having a plurality of apertures with an average narrowest diameter of from 30 micrometers to 5000 micrometers. The heterogeneous filler can enhance low frequency performance without significantly compromising high frequency performance, thickness or weight.

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).
