On this page, you'll find success stories of two kind of analysis: small and large studies. 

Simple Study : process optimisation

Client : EIRPAC ( Aytré 17 )

Date :  April 2006.

Context :

The company, EIRPAC, manufactures a series of composite pieces under subcontract.  In the   Springtime 2006,  the  EIRPAC company was in the prototype phase for a fiberglass/polyester sandwich fence including 3 metal prototype which beforehand was produced in series by a process, R.T.M. Light.

Goal:

The object of this study was to simulate the injection of  panel sandwichs and to confirm the feasibility  of the piece with the principal parameters of the fabrication process defined by  EIRPAC. It was also to  determine the influence of air void variations,  in the resin flow direction, and the appearance of non-impregnated zones.

Full Study : Process - tooling - piece

Client : Fountaine-Pajot Catamaran ( Aigrefeuille 17 )

Date : August 2005 - March 2006.

Context :

The production shipyard  Fountaine-Pajot wished to reduce fabrication time and production costs for the decks of their new small 36 foot catamaran models. The company had evaluated different fabrication processes and wished to validate and optimise the “injection process”  production method, « Eco »

Goal:

The initial objective of the study was to validate and optimise the implementation method, the injection  process  RTM light, for the complete catamaran deck of the 36  « Mahé ».

This work consisted of :

• Determining the physical characteristics of the cloth material and resin.
• Simulating the deck to validate the adequacy of the process with respect to the pieces' dimensions.
• Validating the simulation results by testing with 1/5 scaled models.
  Creating alternative configuration simulations to optimise the processes.

At the center of the study, our role was enlarged and we were also requested to:

• Define the laminate schedule for the tooling and notably to design a metal structure  to turn over the molds during the different construction phases.
• To validate the laminate schedule for the new piece fabricated by the new process.

The production line has been running stop less since Autumn 2006 and more than hundred boats have been produced using our injected deck. A great sucess for the shipyard and for us.
