MTorres makes a big impression in Paris

Very prominent amongst new products exhibited at last week’s JEC World in Paris was the aircraft structure made with a new process developed by Spain’s MTorres, achieved with fully-integrated reinforcement and without the use of moulds.

The new manufacturing process for large composite structures claimed the 2018 JEC Innovation Aerospace award for the benefits it can provide including:

  • A dramatic reduction in tooling of up to 70%.
  • A manufacturing costs reduction of up to 40%.
  • Weight reduction due to the elimination of fasteners.
  • Topological optimisation of the reinforcements.
  • New flexibility in processing.

In the process, the elementary composite components are prefabricated and joined together to create an initial structure geometry that acts as a mould for the external structural skin.

The initial structure then remains inside the final product as an additional structural component. This allows for a co-curing process for both the skin and the initial components, creating a single final structure.

Initially focused on the manufacturing of fuselages, an out-of-autoclave manufacturing process was chosen for all the components used. Infusion-based production avoids the need for autoclave curing while using the company’s internally-developed low-cost dry carbon fibre tows for the automated fibre placement process – further reducing costs.

The Russian company JSC Aerocomposite was also a finalist in the Aersopace category at the 2018 JEC Innovation Awards, for the new infusion technology it has developed for aircraft wings. These wings are the first in the world to be built using dry carbon fibre and are also manufactured using MTorres equipment.
