Summary
DELTA aims to develop and execute innovative experimental testing procedures for thermoplastic resin based carbon fibre reinforced polymers (CFRPs) aircraft fuselage panels. Based on test procedures applying representative stress states of the real loading cases to which fuselage is subjected at sub-component level, and single loading conditions at the level of structural details. The outcomes of this project will enable the validation of this concept design and out-of-autoclave manufacturing process proposed for a composite material with thermoplastic polymer matrix. Ultimately, validation of this structure will contribute to increase maturity level of multifunctional fuselage demonstrator pursued by LPA IADP Platform 2.
Composite material characterization has the particularity that the properties of the material are not only affected by the raw material but also highly influenced by the manufacturing process. Validation of this structure will contribute to increase maturity level of multifunctional fuselage demonstrator.
A test campaign will be defined and executed following Building Block Approach from structural details up to subcomponent level. First, key material properties will be obtained through low-complexity level tests. Then, a curved panel test system which allows to apply combined loading representative of aircraft in-service life conditions will be used. Innovative tooling solutions will be incorporated in the design of the panel interfaces which will be optimized through FEM simulations developed to assess the influence of the tooling on the load redistribution that occurs during the test execution. The test system enables a high level of accuracy while offering flexibility, as well as a reduction of costs and lead times. The intended testing campaign at the subcomponent level will allow TRL 6 demonstration, by applying coupled and uncoupled load states (e.g. pure compression, compression plus internal pressure).
