Liquid Resin Infusion Simulation Project Completed

  • Friday, 4th June 2010
  • Reading time: about 2 minutes

The PreCarBi European Research Consortium, initiated three years ago, had the main objective of developing a new generation of binder composite materials and associated simulation tools.

The scientific aim of PreCarBi consortium was to develop new binder composite materials that would allow pre-form designs to be manufactured and shaped under high temperature; or local tow reinforcement to be added under high temperature. This resulting research is considered an important contribution for advanced Liquid Resin Infusion (LRI) technologies to compete with expensive and complex pre-preg composite technologies.

Overall, the research consortium, coordinated by ESI GmbH, included two aircraft manufacturers: Airbus and Eurocopter; a tier one supplier: FACC; three materials manufacturers: Toho Tenax Europe, Sigmatex and Huntsman Advanced Materials (Switzerland) GmbH; a digital simulation software supplier: ESI Group; and four universities and research institutes: Cranfield University, IPM Latvia, University of Patras and SICOMP.

Different draping and injection strategies were finally tested on three industrial demonstrator parts using the new materials and the Liquid Composite Moulding (LCM) manufacturing feasibility analyzed during the research project. “Composites have become the material of choice for many advanced aircraft structural applications, but research is still required to identify more cost effective manufacturing and simulation tools to optimize their manufacturing and design”, said Dr. Anthony Pickett, Scientific Director at ESI GmbH. “The PreCarBi project has made a significant contribution to a new binder composite that will have a significant impact on the composite manufacturing industry and the aircraft manufacturing industry as a whole.”
