  • Publication number: 20220258438
    Abstract: A method for molding a composite material includes arranging a prepreg on a jig molding surface of a jig for molding. The method includes sealing a first endless seal region that surrounds the prepreg is formed by bonding a resin bag and the jig molding surface by a first sealing material and a second endless seal region that surrounds the prepreg and is positioned outside the first seal region is formed by bonding a resin bag and the jig molding surface by a second sealing material. The method includes depressurizing a first space inside the first seal region and a second space between the first seal region and the second seal region are depressurized. The method includes thermally curing the prepreg by supplying a water vapor into the internal space of a pressure vessel, while holding the pressure vessel in a sealed state.

  • Publication number: 20220176659
    Abstract: A fitting method is for fitting a material to be repaired and a repair patch to be adhesively bonded to the material at adhesive surfaces, each adhesive surface having at least two or more of curved portions. The fitting method includes measuring a shape of the material; measuring a shape of the repair patch; dividing repair patch shape measurement data acquired at measuring the shape of repair patch into pieces of divided data each including one or less of the curved portions; performing, at the adhesive surfaces, fitting processing of the pieces of divided data acquired at dividing the repair patch shape measurement data to material-to-be-repaired shape measurement data acquired at measuring the shape of material; and calculating a gap amount between the material-to-be-repaired shape measurement data and repair patch shape fitting data acquired from the fitting processing at the adhesive surfaces.

  • Publication number: 20220143935
    Abstract: A composite material molding method includes a first disposition step for disposing a prepreg on a jig molding surface of a molding jig; a first sealing step for airtightly sealing the prepreg by covering the prepreg with a first resin bag; a second disposition step for disposing a breather so as to cover the first resin bag; a second sealing step for airtightly sealing the breather so as to cover the breather with a second resin bag; a first depressurization step for depressurizing a first space sealed by the first resin bag; a second depressurization step for depressurizing a second space sealed by the second resin bag; and a heat-curing step for heat-curing the prepreg by supplying the internal space of a pressure vessel with a steam with a predetermined temperature and a predetermined pressure.

  • Patent number: 11084227
    Abstract: A method for performing thermo-fusion additive fabrication so as to allow the fusion with a member shaped by an arbitrary method, a method allowing a thermo-fusion additive fabrication object to be surely fused with another member, and a structure at least partially including the thermo-fusion additive fabrication object are provided. A method for performing thermo-fusion additive fabrication such that fusion can be performed on a shaped member even afterward includes: a step of providing a near infrared ray absorption material on the member by the thermo-fusion additive fabrication, the near infrared ray absorption material containing a near infrared ray absorption agent that absorbs a near infrared ray and a resin in which the near infrared ray absorption agent is dispersed; and a step of providing a thermoplastic resin material on the near infrared ray absorption material by the thermo-fusion additive fabrication.

  • Patent number: 10717243
    Abstract: Provided is a preform member bonding method of bonding a preform member and another member with an adhesive in an RTM process. The preform member bonding method includes increasing viscosity of the adhesive by heat-treating only the adhesive in advance before inserting the adhesive between bonding surfaces of the preform member and the other member.

  • Patent number: 10618229
    Abstract: In a molding method using a VaRTM process in which a workpiece is impregnated with resin in a vacuum, the flow channel resistance or the thickness of which is not constant, an air-permeable sheet only permeable to gas and not permeable to resin (liquid) is arranged at the bottom surface of the workpiece to cover the total length of the workpiece in a direction in which the flow channel resistance or the thickness of the workpiece varies, to impregnate the resin.

  • Patent number: 9993949
    Abstract: Provided is a preform member bonding method, in a RTM process, for bonding a preform member and another member (a preform member or a hardened member) together with an adhesive. The preform member bonding method includes: beforehand obtaining data on a range of a level of progress in hardening of the adhesive which allows the adhesive to penetrate the preform member, and data on a range of the level of progress in the hardening of the adhesive which decreases bonding strength of the adhesive; and controlling the level of progress in the hardening of the adhesive by heat-treating the adhesive based on these data, before the preform member comes into contact with the adhesive.
