Flammability of GRP for use in ship superstructures

Abstract

Abstract The burning characteristics of glass‐reinforced panels with an isophthalic polyester resin, the same resin with an inorganic flame retardant, two differing vinylester resins or a resole phenolic as the matrix were tested at a range of incident heat flux values using a cone calorimeter. The phenolic composite was superior at all levels showing a longer ignition time, reduced heat output, less contribution to a low‐level sustained fire (25 kWm −2 ) and lower smoke yield.
