Failure Prediction Technique for Compression Loaded Carbon Fibre-Epoxy Laminate with Open Holes:
TL;DR: In this article, the inplane compressive fracture behavior of a carbon fiber-epoxy laminate containing a single hole is examined. Failure is due to 0° fibre microbuckling surrounded by delamination.

Compressive failure of notched carbon fibre composites
TL;DR: In this article, the compressive fracture properties of carbon fiber/epoxy laminates were investigated in terms of existing theories of strength, and it was found that compressive failure is governed by plastic microbuckling of the 0° plies.
