Provided a composite material forming method capable of easily using a composite material that is formed by causing a resin to react in a state where it is joined to another member; and a composite material. The composite material forming method includes a first material preparation step (magnetic field circuit forming material preparation step S11), a second material preparation step (magnetic field circuit non-forming material preparation step S12), a material assembly step S13, and a first heating step (magnetic field heating step S14). In the first material preparation step, a first material including a first resin is prepared. In the second material preparation step, a second material including a second resin is prepared. In the material assembly step S13, the first material and the second material are assembled to each other.

A method forms a butt joint between ends of first and second plies and splices the first and second plies together. The method includes the steps of: positioning a first splice edge of a first ply at a first location; positioning a second splice edge of a second ply at a second location, the second splice edge being left bare; wrapping a gum strip around the first splice edge such that the first gum strip forms a U-shaped structure in section that allows the first gum strip to extend from a first planar side of the first ply over the first splice edge to a second opposite planar side of the first ply; not wrapping a gum strip around the second splice edge; placing the first splice edge in abutting relationship to the second splice edge; and stitching the first splice edge to the second splice edge such that stitches each extend from the first planar side of the first ply, through the gum strip, to the first planar side of the second ply.

A metal-carbon fiber reinforced plastic composite comprising a metal member of a ferrous material or ferrous alloy, a resin layer provided on at least one surface of the metal member and including a thermosetting resin, and carbon fiber reinforced plastic provided on a surface of the resin layer and including a carbon fiber material and a matrix resin having thermoplasticity, an indentation elastic modulus at 160 to 180° C. of the resin layer being higher than an indentation elastic modulus at 160 to 180° C. of the matrix resin.

It is possible to prevent a tip portion of a guide portion in a spiral pipe-forming apparatus allowing an inner periphery restriction body to be omitted from colliding a peripheral surface portion of a non-circular existing pipe. A non-circular guide portion (73) is provided so as to be rotatable with respect to an apparatus frame (3a) around a rotary axis (32). The guide portion (73) is applied to a peripheral surface of a preceding spiral pipe portion (91). An acting portion (41) acts such that the guide portion (73) follows the peripheral surface of the existing pipe (1).

Both diameter expansion and contraction control and fitting stabilization are achieved at the same time in a pipe end release-type pipe-forming apparatus having a non-inner periphery restriction structure. A driving part (10) provided in an apparatus frame (30) of a pipe-forming apparatus (3N) presses an unformed following strip portion (92) of the strip member (90). A reverse side guide portion (83) is engaged with a pipe end portion (91e) of a preceding spiral pipe portion (91) from a reverse side. A face side guide portion (82) is engaged with the pipe end portion (91e) from a face side. The face side guide portion (82) is shifted to the propulsion rear side beyond the reverse side guide portion (83). The following strip portion (92) is extruded from the driving part (10) toward an inter-guide clearance (84) between the reverse side guide portion (83) and the face side guide portion (82). Preferably, the driving part (10) is position-adjustably attached to the guide portions (83), (82) or the apparatus frame (30) via a position adjustment mechanism (31a).

Disclosed are thermoset/thermoplastic composites that include a thermoset component directly or indirectly bonded to a thermoplastic component via a crosslinked binding layer between the two. The crosslinked binding layer is bonded to the thermoplastic component via epoxy linkages and is either directly or indirectly bonded to the thermoset component via epoxy linkages. The composite can be a laminate and can provide a route for addition of a thermoplastic implant to a thermoset structure.
