  • Patent number: 10040258
    Abstract: A method for obtaining a composite piece of n plies, at least one ply having a fiber volume greater than 58% in weight, the method comprising the steps of laying uncured prepreg plies and performing ultrasound compaction over each laid uncured laminate ply, wherein at least one of the uncured laminate plies has a fiber volume greater than 58% in weight. Finally, the composite laminate is cured. The step of performing ultrasound compaction comprises applying an ultrasonic compactor over each laid laminate ply.

  • Patent number: 7678437
    Abstract: A mechanically fastened permanent or detachable joint between two or more parts (21, 23, 25, 41), at least one of them made of a composite material, preferably carbon fibers impregnated with thermoset resin, with continuous plies from the full-composite area along the joint area (15) and including a metal reinforcement, preferably made of titanium, in the joint area (15), the joint area (15) thickness being increased in the thickness of said reinforcement plus the eventual additional composite plies laid only on the reinforced area. The metal reinforcement may consist of one or more metal foils or sheets (31) interleaved between the composite plies or one or more metal plates (33) embedded between two of the composite plies.

  • Publication number: 20090151865
    Abstract: The invention relates to a jig (9) for manufacturing composite material parts out-of-autoclave, comprising a base (11) the upper surface of which includes a stacking table (13) having a rotating movement and a shifting movement in the laminating direction, and a head (15) supported on a portal frame (17) through means allowing the shift perpendicular to the laminating direction on the mentioned table (13), the head (15) in turn comprising: automatic means (21) for placing tapes or roves of composite material in the form of prepreg; compacting means (23) for compacting the composite material and curing means (25) for polymerizing the composite material. The invention also relates to an out-of-autoclave process for manufacturing composite material structures.

  • Publication number: 20080023130
    Abstract: This invention relates to a tool (9) for manufacturing pieces of composite material outside an autoclave comprising a stacking table (11); a movable head (15) on said stacking table (11) provided with: automatic means for placing tapes (19) of composite material; compacting means for compacting the composite material and microwave emission means (25) to cure the composite material. The invention also relates to a process for manufacturing pieces of composite material outside an autoclave, comprising the following steps: a) Placing composite material in the form of tapes on a tool with the shape of the piece to be manufactured, compacting it and partially curing it after its placement until completing a layer of the piece; b) Repeating step a) until completing the stacking of the piece and c) Curing the last layer of the piece until the required degree of curing.
