TL;DR: In this paper, the authors examined the compression creep rupture behavior of a glass/vinyl ester composite subject to combined load and one-sided heating simulating fire exposure, and focused on reversible non-linear viscoelastic effects which dominate delayed failure at lower temperatures in the vicinity of the glass transition temperature.

Abstract: Given the expanding applications of polymer matrix composites to civil infrastructure, the marine industry, and the military, we examine the compression creep rupture behavior of a glass/vinyl ester composite subject to combined load and one sided heating simulating fire exposure. We focus on reversible non-linear viscoelastic effects which dominate delayed failure at lower temperatures in the vicinity of the glass transition temperature. A compression strength model which predicts local compression failure due to micro-buckling is extended to include viscoelasticity. Times to failure under combined mechanical load and one sided heating are estimated to within an order of magnitude.

Post-fire compressive behaviour of carbon fibers woven-ply Polyphenylene Sulfide laminates for aeronautical applications
TL;DR: In this paper, the influence of fire exposure on the residual compressive behaviors of carbon fibers woven-ply Polyphenylene Sulfide has been investigated for aeronautical applications, showing that prior fire exposure is highly detrimental to the compressive mechanical properties as the residual strength and stiffness decrease by approximately 75% and 55% respectively.

Compressive failure of fibre composites
TL;DR: In this article, a review of experimental data and elementary theoretical formulas for compressive failure of polymer matrix fiber composites indicates that the dominant failure mode is by plastic kinking, which plays a central role in the local fiber misalignment.
