  • Publication number: 20210156337
    Abstract: A cylinder block includes a body part where a cylinder is formed, an outer wall part made of fiber reinforced resin and surrounding an outer circumference of the body part, and a metal member attached to the outer wall part. The outer wall part is comprised of an inner layer surrounding the outer circumference of the body part, and an outer layer surrounding an outer circumference of the inner layer. A density of reinforcing fiber contained in the outer layer is higher than a density of reinforcing fiber contained in the inner layer. The metal member is attached to the outer wall part so as to contact the outer layer. The reinforcing fiber contained in the outer layer has an electric insulating property.
    Type: Application

  • Patent number: 11002220
    Abstract: A cylinder block includes a metal body part having a cylinder, and an outer wall part made of fiber reinforced resin, surrounding an outer circumference of the body part. A part of the outer wall part at BDC side in a cylinder axis direction contacts a bottom wall forming part. The outer wall part is comprised of an inner layer surrounding the outer circumference of the body part, and an outer layer surrounding an outer circumference of the inner layer. A density of reinforcing fiber contained in the outer layer is higher than that in the inner layer. A thickness of a part of the inner layer at BDC side in the cylinder axis direction is greater than that of the TDC-side inner layer. A thickness of a part of the outer layer at TDC side in the cylinder axis direction is greater than that of the BDC-side outer layer.

  • Patent number: 9963579
    Abstract: A thermoplastic resin molding according to the present invention contains carbon fibers. An amount of the carbon fibers falls within a range from 0.4 mass % to 10 mass %. An average length of the carbon fibers falls within a range from 0.5 mm to 15 mm. The thermoplastic resin is polypropylene. The polypropylene includes polypropylene containing at least one of a carboxyl group, a carbonyl group, or a hydroxyl group. Surfaces of the carbon fibers contain at least one of a carboxyl group, a carbonyl group, a hydroxyl group, or a Cl group.

  • Publication number: 20160325488
    Abstract: In thermal pressure joining of joining a metal member to a resin member, a metal member (11) and a resin member (12) are stacked one on the other, a press member (160) applies heat and pressure locally on the metal member to soften and melt the resin member, the resin member is then solidified, the press member (160) is pressed into the metal member (11) to a depth shallower than a joint boundary (13) between the metal and resin members to deform a portion (110) of the metal member directly under the press member such that the portion protrudes toward the resin member, and resin (121) melted on a surface of the resin member in a region (60) of the joint boundary directly under the press member flows to an outer periphery (61) of the region (60).
