A carbon fiber composite material (10) configured from carbon fiber prepregs (11, 13) and a porous prepreg (21) interposed therebetween, the surface of the carbon fiber composite material (10) being configured from the carbon fiber prepregs (11, 13), wherein at least one surface of the carbon fiber composite material (10) has recesses (101, 103) and/or protrusions formed. Under the recesses (101, 103), the thickness of the porous prepreg (21) has been made smaller than that in the general part (111) having neither recesses nor protrusions, and the carbon fiber composite material (10) has a reduced thickness. Under the protrusions, the thickness of the porous prepreg has been made larger than that in the general part (111) having neither recesses nor protrusions and the carbon fiber composite material (10) has an increased thickness.

A duct of the present invention includes a pair of groove-shaped members which are formed of sound absorbing sheets and a pair of flange portions which are formed of parts of the pair of groove-shaped members that are extended outward from groove opening edges and which are joined in an overlaid state on each other when the pair of groove-shaped members are arranged such that groove openings are opposed to each other. The pair of flange portions includes a seal portion which is formed by crimping the sound absorbing sheets in parts of the flange portions along the groove opening edges and an outer thick portion which is extended outward from the seal portion and which is formed of the sound absorbing sheet thicker than the sound absorbing sheet of the seal portion.

A resin molded article for, for instance, vehicles formed thereon a stitch pattern, including a first member (32) having a plurality of thread stitch portions (34, 36) protruding towards a design surface (31) and formed on a front side in alignment and a second member (44) formed such that the front side of the first member (32) is covered thereby and the protruding ends of the thread stitch portions (34, 36) are exposed from the second member (44). The surface of the second member (44) constituting the design surface (31) and the protruding ends of the thread stitch portions (34, 36) exposed from the second member (44) are in colors different from each other, and stitches in a stitch pattern are configured on the design surface (31) of the resin molded article by the plurality of thread stitch portions (34, 36).

Polyurethane foam is formed by foaming raw materials that includes either an aliphatic isocyanate or a melamine derivative, a urethane emulsion, and an anionic foam stabilizer. The compression set (JIS K6401) of the polyurethane foam, specifically, the compression set (JIS K6401) after the polyurethane foam being allowed to stand for 22 hours in a state of 50% compression under condition of 70 C., is 40% or less. By this, it is possible to obtain polyurethane foam that is low density, pliable and resistant to collapse, i.e., polyurethane foam having high recovery properties.


The invention provides a carbon fibre reinforced composite material exhibiting excellent reprocessing and recycling properties and a suitable surface smoothness while ensuring reduction in weight and thickness, and high stiffness. The present invention provides a carbon fibre reinforced composite material including at least two carbon fibre fabrics and a thermoplastic resin, wherein each of the at least two carbon fibre fabrics is formed of an opened yarn obtained by opening a carbon fibre bundle, and the thermoplastic resin is impregnated with the at least two carbon fibre fabrics in a solidified state such that the carbon fibre reinforced composite material is formed integrally as a whole, and a method for producing thereof.
