Analysis of Bending Stiffness Reduction in Thin Woven Composites Under Large Curvatures

We are pleased to share an undergraduate research study conducted under the Department of Civil Engineering, University of Moratuwa, investigating the bending stiffness reduction of ultra-thin woven composite laminates under large curvatures, a key challenge in deployable space structures.

This study, carried out by Pamith Ranatunga under the supervision of Prof. Chinthaka Mallikarachchi, adopts a detailed numerical modelling framework to identify the dominant mechanisms governing stiffness loss, with particular focus on inter-ply interface behaviour.

Through this initiative, the Civil Engineering Society aims to highlight high-quality undergraduate research and provide a platform to share impactful academic work with the wider professional and research community.
