Experimental building block approach and numerical modelling of thermoplastic composite used for fuselage panels

Abstract

The present work focuses on the experimental and numerical investigation of thermoplastic composite aircraft structures through a building block approach [1-3]. Numerical simulations take part as to derive a preliminary behavior of the thermoplastic composite material and extract the optimum geometry and stacking sequence and then validation comes from the experimental campaign. The tests are extended from material characterization coupons to the demonstrator multistiffener panel
