The purpose of the FIRE-RESIST project, a European Commission supported project, aimed at improving the fire performance of high performance polymer matrix composite materials for the transport sectors. One concept for load carrying structures was developed for marine applications. This concept was a sandwich consisting of three cork cores and four furan/glass fibre laminates. The ambition with the multiple layer design was to create a structural redundancy allowing parts of the sandwich cross-section to decompose when exposed to fire without a total loss of load carrying capacity. A limited engineering analysis with regards to SOLAS II/2-17 was performed resulting in a set of requirements on the fire behaviour of the sandwich. A series of tests, both small and large scale, were performed to investigate if these requirements were met. The results from these tests show that the requirements were met when an intumescent coating was applied. All test procedures and results are documented in this report.
