Abstract:
An innovative repair process and evaluation are proposed. Firstly, the originality of this work consists on the process used for the repair milling: an Abrasive Water-Jet milling. A doublestep lap coupon is chosen to demonstrate the feasibility of the milling process. This specimen is made of M10.1/38%/UD300 CHS 460 from Hexcel Composites. After milling, the removed material is reconstructed laying up the same prepreg material with a one-ply shift in the staking sequence. A Redux 609 adhesive film is used to ensure a correct bonding on the interface. Secondly, the originality concerns the mechanical characterization of the repair quality assessed through an innovative multi-axial mechanical test. It allows to choose multiaxial loadings according to the requirement. The selected test is a combined bending and compression test. Finally, results of mechanical tests are presented and discussed.
