LRI MODEL VERIFICATION AND VALIDATION TESTS

Verification and validation tests for the LRI simulation model were completed with satisfactory results.

Numerical verification was performed by means of correlation with the theoretical model while the validation tests included infusion and LRI tests carried by CIDAUT using the RTM6 resin and the UD carbon fibre reinforcements characterized previously during the project. A good correlation was achieved between the simulation and experimental results.

The LRI simulation models developed within the PLIT project will be very useful for the optimization of the set-up of the LRI processes for large stiffened wing panels, as a valuable engineering tool to evaluate alternative impregnation strategies.
