Patent number: 10773475Abstract: This process for producing a thermoplastic composite part by laying of at least one thermoplastic composite layer on a tool includes laying on the tool a hardened first ply before the laying of the thermoplastic composite layer. The first ply is produced beforehand to the shape of the tool and includes a first material able to experience an attractive force when it is subjected to a magnetic field, and/or to an electrical potential difference, and includes a second material of a thermoplastic resin that is chemically compatible with the resin of the thermoplastic composite layer. The first ply is clamped to the tool by the effect of a magnetic field, and/or of an electrical potential difference, established at the level of the tool. In one form of implementation, the first ply is produced on a first-ply mold that is preferably of convex shape.Type: GrantFiled: December 12, 2014Date of Patent: September 15, 2020Assignee: Airbus SASInventor: Eric Soccard

Patent number: 10369750Abstract: The device for welding thermoplastic parts includes a matrix for positioning the parts to be assembled, the matrix including an amagnetic insulating insert that defines joining zones in which the welds must be produced, a bladder defining a sealed volume and means for producing a partial vacuum in the sealed volume, and means for moving a magnetic induction head to near the joining zones and without making contact with the bladder. The welding process includes positioning at least one first part, then of placing metal inserts on areas of the first part corresponding to the joining zones that must be welded, and then positioning at least one second part. A bladder is put in place covering the parts and a partial vacuum is created in the volume defined by the bladder. The magnetic induction head is moved to produce the weld bead without contact while the partial vacuum is maintained.Type: GrantFiled: March 19, 2015Date of Patent: August 6, 2019Assignee: Airbus SASInventor: Eric Soccard

Patent number: 8252134Abstract: According to the invention, one or more thermoplastic sheets (NdT: “feuilles thermoplastique” in the original) (2) are applied on a flat or curved tool (13), and strips (NdT: “des bande” in the original) of a polymer are applied and pressed onto the sheets (2). They are maintained by suction pumps (8), the orifices (4) of which open into a closed volume or one substantially delimited by a sealing joint (3) and occupied by a draining fabric (7). The heating treatment concomitant to the deposition to harden or consolidate the prepreg softens the sheets (2), distorts them to the curvature of the tool (13) and incorporates them in the structure of the prepreg. Application to methods of draping parts with composite material.Type: GrantFiled: February 5, 2008Date of Patent: August 28, 2012Assignee: European Aeronautic Defence and Space Company-EADS FranceInventor: Eric Soccard

Patent number: 7914272Abstract: The system for stretch-forming composite material bands (3) includes, in addition to an unrolling head (20), an original assembly composed of a light source (4) for heating the band (3) and hardening the composite and a pair of rollers (6a and 6b) applying the desired pressure to assemble the band to a laminated composite (2) already deposited or applying it to the support (1). As the application of heat is concentrated at a distance from the rollers (6a and 6b) and with a perpendicular incidence, the rollers can be conveniently made of an elastic material, which enables them to adapt to the transverse curvature of the support equipment (1) and to apply a uniform pressure.Type: GrantFiled: December 2, 2005Date of Patent: March 29, 2011Assignees: European Aeronautic Defence and Space Company, Dassault AviationInventor: Eric Soccard

Patent number: 7896994Abstract: A method for assembling at least two rigid thermoplastic material based parts. The two parts are superposed to have at least one interface zone, wherein at least one of the two parts includes one or plural energy directors, protruding, situated in the interface zone. At least one excited ultrasonic source is brought into contact with one of the two parts, the ultrasonic source applying a compression effort to the two parts in a region of the interface zone located opposite the ultrasonic source. The ultrasonic source is continuously displaced at the interface zone to form a continuous welded joint by fusion of the thermoplastic material in the region positioned opposite the ultrasonic source. Such a method may find particular application for assembly of stratified parts.Type: GrantFiled: July 3, 2006Date of Patent: March 1, 2011Assignee: European Aeronautic Defence and Space Company-EADS FranceInventor: Eric Soccard
