Current Research


My main research is about experimental and theoretical analysis of glass/carbon hybrid fiber laminates. Several approaches are being used for analyzing/monitoring damage initiation and propagation inside hybrid fiber laminates. The importance of hybrid fiber laminates becomes even more significant for engineering application which require more ductile laminates compared to CFRP composites. The apparent failure of hybrid fiber composites compared to similar CFRP laminates is called hybrid effect which requires very thorough investigation. Using multi-instrument approach to understand hybrid effect is a promising way to predict behavior of hybrid fiber composite.

Acoustic emission is concurrently used with digital image correlation and thermography techniques to specify effect of stacking sequence and load type on hybrid fiber laminates. Damage accumulation is observed throughout loading of samples and correlated with stress-strain curves of each sample.
