    摘要: A machine for filament winding, in particular on a liner for the manufacture of tanks, comprising a displacement system able to drive a body in rotation around its longitudinal axis (A) and to effect a relative displacement of the body with respect to winding means. The winding means comprise a rotating support, mounted so as to rotate around a rotation axis (B), on which are mounted at least two winding systems, each winding system comprising a winding head associated with storage means, so that, by rotation of said rotating support around its rotation axis (B), each winding system can be displaced into an active position for winding fiber via its winding head, and an inactive position in which an operator can perform maintenance operations.

    摘要: A composite tube comprising a region of greater diameter forming a bellow. The bellow has a first side and a second side spaced apart in the axial direction of the tube. Each side of the bellow comprises at least one hole and the at least one hole on the first side is offset in relation to the at least one hole on the second side. The holes in the bellow provide increased flexibility, thereby allowing a greater amount of bending or articulation in the shaft. The holes reduce the amount of material in the sides of the bellow, thereby reducing the material stiffness and thereby increasing the flexibility.

    摘要: A cylindrical winding body is formed by winding continuous fibers impregnated with a first thermosetting resin in a circumferential direction, and the first thermosetting resin in the winding body is thermally cured. A pair of dome members is joined to both end portions of the cylinder member. A fiber bundle impregnated with a second thermosetting resin is helically wound around the joined member over the dome members, and the second thermosetting resin in the wound fiber bundle is thermally cured. A thermosetting resin containing a main agent and a granular solid curing agent is used as the first thermosetting resin, the main agent including a resin precursor and the solid curing agent chemically bonding molecules of the resin precursor together.

    摘要: Resiliently flexible articles include a resiliently flexible element, a first rigid element, and a second rigid element. The resiliently flexible element is formed of a fiber reinforced polymeric composite. The first rigid element is formed of a first thermoplastic composition and at least a portion of the first rigid element is bonded, such as by an overmolding process, onto a first portion of the resiliently flexible element. Similarly, the second rigid element is formed of a second thermoplastic composition and at least a portion of the second rigid element is bonded, such as by an overmolding process, onto a second portion of the resiliently flexible element. The resiliently flexible articles can be useful as springs, limbs, living hinges, and the like.

    摘要: A pressing member is configured to press a portion-to-be-pressed of a continuous-fiber sheet against a recessed surface of a first mold in a state where the continuous-fiber sheet is placed between the first mold and a second mold. A pulling member is configured to bring the continuous-fiber sheet into close contact with the main surface and the recessed surface by pulling a portion of the continuous-fiber sheet located on an outer peripheral side of the portion-to-be-pressed after the pressing member presses the portion-to-be-pressed against the recessed surface.
