    Evaluation of the Residual Strength of a Polyester/E-Glass Composite Tray After Exposure to High Temperatures Due to a Nearby Fire Event

    The mechanical behavior of pultruded polyester/E-Glass trays was evaluated as a function of high temperature exposure time at 250°C. This temperature was chosen based on the composite’s thermal behavior, which wa...
