This study presents experimental results of compression after impact (CAI) testing of aluminum honeycomb core sandwich structure with face sheets made of quasi-isotropic carbon/epoxy with two orthogonal directions of testing. In a previous study exam

For the past six years, we have been benefiting from the discovery by Tsai and Melo (2014) that the trace of the plane stress stiffness matrix ( tr ( Q ) ) of an orthotropic composite is a fundamental and powerful scaling property of laminated compos

Notched compression strength of 18-ply laminates with various percentages of 0° plies

Autor: Alan T. Nettles

Publikováno v: Journal of Composite Materials. 49:495-505

The use of knockdown factors (percent reduction of undamaged compression strength) to account for flaws such as impact damage or holes have been used to infer the notched strength of laminates. It has been observed that this criterion tends to over-p

Normalizing impact energy by face sheet thickness for composite sandwich structure compression after impact testing

Autor: Alan T. Nettles

Publikováno v: Journal of Sandwich Structures & Materials. 15:340-358

The amount of impact energy used to damage a composite laminate face sheet of a sandwich structure is a critical parameter when assessing residual compression strength. The compression after impact strength of impacted laminates used as face sheets o
