Conseil & Technique, an SME dedicated to the development of new products

Successful partners
Since its creation, Conseil & Technique, based in Toulouse, France, has developed its own unique know-how in the design of composite parts. It all began with the daunting technical challenge of producing parts for Jean-Louis Etienne and his boat, Antarctica (now named Tara).
t the helm of the company, Guy Valembois has always striven to build the development of the company upon technical innovation, through observation of nature and through lessons learned from the history of design. His approach is simple: never let it be a question of replacing the existing metal part with an identical composite part, but rather of “thinking composite” from the earliest design phase, so that the concept is integrated right off the drawing board.

Connecting rods with high mechanical properties

composites – rods with high mechanical properties, a damping layer and attachment fittings for primary and/or secondary structures – C&T has secured SKF Aerospace France as one of its major customers and partners. Their two technical teams have succeeded in confirming the industrial potential of certain innovations which are sure to be the keys to future commercial success.

Nowadays specialising in the mechanics of movement and composite parts, Conseil & Technique is a recognised player in the aerospace industry. It has over 130 international patents to its name and proposes new approaches for resolving technical problems from a fresh perspective. Since it does not have the technical manufacturing facilities required by the aerospace sector, the company has established strong partnerships and technical relationships with its customers. Since 2008 and the advent of three major innovations in the field of

After several trials, the C&T and SKF teams, in association with the association of BTS INDUSTRIE and network of SMEs, have succeeded in manufacturing large-scale composite components, such as landing gear struts. Although this may not be a pure innovation as such, when you succeed in associating this manufacturing process with the use of prestressing in the composite part itself, what you have is quite simply a world's first. The targeted uses of such a product

The stress levels obtained thanks to the complementary know-how of the respective teams are quite exceptional: Centre-to-centre distance: 850 mm Overall net weight: 4.2 kg Ball joints: Steel Tensile and compression strength: 500 kN (50 T) Breaking stress: 2,600 MPa

underline the fact that the company is capable of replacing steel rods with prestressed composite rods in extreme environments and, as a consequence – given identical technical specifications – of offering weight savings, volume savings and far superior compression or tensile strength.

The teams are moving ahead at full tilt in order to be able to propose these new solutions to the big aerospace companies. To this end, they have moved into the development stage (TRL4). A second phase will involve evaluating other aerospace applications. The technical collaboration between the two teams does not end there, since they are continuing to develop new processes for the manufacturing of composite parts.
