Non-destructive inspection methods for re-usable CFRP structures
Secure NDI methods for CFRP structures are mandatory to guarantee re-use of reusable launcher structures like CFRP
LH2-tanks or to identify maintenance or repair needs. Baseline technology and widely used is ultrasonic inspection (US), but it
has some limitations (exact damage detection and location, damage detection in complex and large structures, mobility of
inspection system, accuracy of information). Other inspection technologies meanwhile reached respective maturity and are
interesting alternatives. It is proposed to perfom non-destructive inspection of structures for RLV, in particular: identification
typical re-usable launcher structures for inspection, Technology Review of Existing Methods, NDI Methods Evaluation
Program (Damage Sample Test Program), Damage Classification for Re-Usable CFRP Structures, CFRP structure test
program (e.g. tank structure), Recommendations and Synthesis.
Deliverables:
Technical notes: survey of typical re-usable launcher structures for inspection and existing methods, NDI Methods Evaluation
Program, Re-Usable CFRP structures damages classification and test program, test specimens.
