摘要： A carbon fiber-reinforced resin molded body of the present invention derives from kneaded materials of a thermoplastic resin and a carbon fiber and includes at least a three-dimensional complex shaped region and a substantially flat plate-shaped region arranged in a profile direction. Fluidity of the kneaded materials at predetermined temperature is such that fluidity of the kneaded material forming the substantially flat plate-shaped region is lower than fluidity of the kneaded material forming the three-dimensional complex shaped region, which makes it unlikely to cause defects in ribs, posses, and other portions. Thus, a carbon fiber-reinforced resin molded body with low cost and high strength can be provided.

摘要： A method for producing carbon fiber reinforced resin molded article of the present invention includes press-molding a mixture-made body including carbon fiber and thermoplastic resin to produce the article that is composed of CFRP.
The method further includes perforating pores into the mixture-made body, before press-molding mentioned above.
As, in perforating, at least the pores are formed so as to penetrate through a hardened part of a surface of the mixture-made body, the article made of the CFRP that does not have poor appearance, such as whitening or marble pattern, can be produced.-

摘要： Provided is a composite (A) including a metal plate (B) and a reinforcing member (C) that is made of a resin. The metal plate (B) includes a joint portion (2) that is continuous with one end of a body portion (1), a hole that is formed through the body portion (1) in a thickness direction of the body portion (1) in the proximity of the joint portion (2), and a guide portion provided around the hole. The reinforcing member (C) continuously includes a main portion (5), a coupling portion (6) formed in the hole (3), and a locking portion (7) that is held in close contact with a surface on another side of the body portion (1). The guide portion (4) is at least one of a protruding portion provided on at least one of a rear side and a lateral side relative to the hole (3) in a direction from the body portion (1) to the joint portion (2), and a recessed portion extended from a front side relative to the hole (3) to the hole (3) in the direction from the body portion to the joint portion. In insert molding of the composite (A), a molten resin is introduced preferentially into the hole (3). With this, the joint portion (2) is formed reliably in good condition free from adhesion of the resin.

摘要： A vehicle body structure includes a resin floor part provided with a flange portion bent toward an upper side or a lower side at an end in a vehicle width direction, and a metal side sill part joined to the flange portion of the floor part. The side sill part includes a rim portion, a peak portion, and intermediate portions that link the rim portion to the peak portion. The peak portion and the intermediate portions form a protruding portion projecting from the rim portion toward the floor part. The flange portion of the floor part is joined to the peak portion of the protruding portion.

摘要： A composite material is formed by irradiating a bonding position on a surface of the composite material with a laser to cause a reinforcing base member of the composite material, that is impregnated with a resin and onto which a bonding agent is applied, to be exposed and fluffed.
