As a matter of fact, the consolidation of composite laminates takes place by the progress of the polymerisation which is activated thermally. The design and control of the autoclave process relies on the capability to manage the relationship between the temperature-pressure cycle of the heat carrier fluid and the temperature distribution through the manufacturing part. In particular, in the industrial cases the main limitations reside in the correct evaluation of the local convective heat transfer conditions through the autoclave and in the evaluation of the local thermal inertia arising from the bagging-tooling system. \nIn this study, the autoclave manufacturing of thick laminates has been addressed by modeling the heat transport phenomena occurring through the composite, the bagging and the tooling system. A new methodology for the evaluation of the energy transfer regimes has been proposed accounting for the heat fluxes from the bag and the tool side, the temperature through-the-thickness gradients and the heat generated by the resin polymerization reaction. The proposed approach enables to predict the temperature history of the autoclave assembly without knowing the effective thermal inertia of the two external layers that could be difficult to evaluate owing to possible deformations of the bag during the manufacturing cycle and not uniform shape of the metallic tool along the part.\nExperimental data from industrial autoclave runs have been collected and analyzed to validate the method.\n" ; prodottidellaricerca:prodottoDi istituto:CDS051 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA8749 , unitaDiPersonaleInterno:MATRICOLA5693 . @prefix parolechiave: . prodotto:ID31695 parolechiave:insiemeDiParoleChiave . parolechiave:insiemeDiParoleChiaveDi prodotto:ID31695 .
