Abstract

Technological innovations applied in the aeronautical sectors prefers the use of structures that are in able to have great advantages in terms of performance with a significant weight reduction. This involves research and development of new materials, in which composite materials have an high importance in the study of new concept structural architecture.

Objective of the presentation is the correlation of results obtained using non-destructive testing, ultrasonic method in particular, with the discontinuity which produce an indication in carbon fiber composites. The indication can be found by ultrasonic method in form of attenuation signal and/or reflection signal.

The characterization of typical defects enucleated in CFRP materials (Carbon Fiber Reinforced Polymer) or CRP (Carbon Reinforced Plastic) will therefore be supported by a significant activity of material testing laboratory.

Laboratory activity will be directed to the identification, quantification and characterization of the discontinuities due to problems and/or failure during the production process.
