Within the context of large introduction of carbon composites in structural part for civil aircraft ( more than 50% in A350 XWB or B787 structure weight) , Composite materials manufacturers and Aircraft Designer are working very close together to ensure that ageing performances are fully understood from initial phase of the qualification program.

Standardized materials screening practices are developed to identify environmental ‘moisture’ effect on overall mechanical performances to tailor CFRP materials, as ageing mechanism is dependent of the nature of matrix and fiber behaviors for a given process

What benefit we take from this to address the long times of service exposure and to answer to the Regulations Requirement of fatigue and damage tolerance on CFRP structures?
Other key sensitive parameters have to be considered in the design, on top of environmental effects, as manufacturing defects, (i.e; bonded joints..) fatigue and accidental damage, sometimes in combination, to show compliance to certification rules.

We propose to illustrate this approach using recent developments and return of experience from Airbus Programs between Composite materials properties and Allowance Design for Structural Aircraft Applications.
