  • Publication number: 20200370650
    Abstract: The sealing method is for sealing between: a rear surface of a first component which is a composite material containing a reinforcing fiber and a resin; and a front surface of a second component facing the rear surface of the first component. The sealing method includes: a step (ST03) in which a molded body is placed at a corner between the front surface and an end surface of the first component, with a first sealing material interposed therebetween; and a step (ST06) in which a second sealing material is applied from the molded body up to the front surface of the second component.

  • Patent number: 10512985
    Abstract: A joint processing method includes: a friction stir welding step for forming a joint in a plate by friction stir welding a groove in the plate; a cold working step for cold working the joint under cold working conditions such that a grain size in the joint is not more than a grain size of an aluminum alloy in the groove prior to the friction stir welding step; and a solution heat treatment step for, subsequent to the cold working step, performing solution heat treatment of the plate.

  • Publication number: 20170209957
    Abstract: This joint processing method comprises: a friction stir welding step S2 for forming a joint 7 in a plate 5 by friction stir welding a groove 6 in the plate 5; a cold working step S4 for cold working the joint 7 under cold working conditions such that the grain size in the joint is not more than the grain size of an aluminum alloy in the groove 6 prior to the friction stir welding step S2; and a solution heat treatment step S5 for, subsequent to the cold working step S4, performing solution heat treatment of the plate 5. This joint processing method can suppress enlargement of the grains of the joint formed by friction stir welding.
