Resins for High Performances composites matrix

Abstract

In collaboration with Astrium / Airbus, the University of Reims Champagne-Ardennes has developed a new solution which improves of the toughness of vinylester thermosetting resins, polymerized under ionizing radiation. This technology is of interest for structural materials in aerospace, transport and chemical applications.

Description

The technology is a high performance vinylester resin made up of acrylate monomers, high-Tg ther-moplastic polymer and reactive solvent.

The use of a high-Tg thermoplastic polymer (polyethersulfone) into the formulation enables to get vinylester resins with enhanced mechanical and thermal properties (see graphs below).

The resin polymerisation is achieved by UV or Electron Beam.

Innovations and advantages of the offer

  • Low energy need due to ionizing radiation (in comparison with thermal mean)
  • Thermoplastic polymers improve the material’s ability to store the energy accumulated during a shock through the interconnected nodular morphology given by this formulation.
  • This monofunctional diluent makes our thermoplastic polymer compatible with an acrylate network

 

Further information

  • High toughness resins and high performances injection
  • These products are polymerized under an electron beam
  • Resins compatible with RTM processes.
  • High Glass Temperature
  • Good mechanical performance with temperature and ageing

 

Application

  • Matrix elaboration for composite materials in aerospace applications
  • Adhesive materials to assemble composite pieces: automobile, armament
  • Fabrication of large-parts: wind turbine blade, holding tank
  • aster production, and production cost reduction for large series

 

Space Heritage

These technologies arise from a collaboration between the University Reims Champagne Ardenne and Astrium within the framework of a thesis. They are used by Astrium to make composite structure (Gossamer) in satellites.
