RECENT INVESTIGATIONS ON ADVANCED COMPOSITE MATERIALS: STRUCTURAL DYNAMICS MODELING, UNCERTAINTY PROPAGATION AND SENSORING

By Domingos A. Rade

(Aeronautics Institute of Technology, Division of Mechanical Engineering)

The present lecture describes some recent investigations devoted to advanced composite materials, including: a) evaluation of the potential benefits provided by the so-called variable-angle tow laminates, in which, by exploring advanced manufacturing techniques, such as automatic fiber placement, the fibers are deposited on the layers following arbitrary curvilinear paths. This extends the possibilities of improving the performance of composite structures in terms of bending, buckling, vibration and aeroelastic behavior, as compared to traditional unidirectional laminates; b) uncertainty propagation, aiming at assessing, in a probabilistic framework, the influence of unavoidable random uncertainties affecting physical, geometric and environmental parameters, on the buckling, vibration and aeroelastic behavior of composite laminates; c) the use of novel sensors based on carbon nanotube fibers for the monitoring of the quasi-static and dynamic responses of composite laminates. The presentation encompasses brief description of the theoretic foundations, as well as numerical and experimental results obtained from the research work.
