Abstract

A manufacturer of a composite panel used for an outdoor application had to replace the panel’s exterior skin because their supplier discontinued the current skin product. They evaluated the modified product using their at-line quality control tests which were not capable of approximating the long-term performance of the panels. Within 6 months customers began reporting failures of the modified panels. Accelerated exposure testing during the skin evaluation process would have identified this failure mode prior to commercialization.
