The residual post-fire mechanical properties of fiber-reinforced epoxy composites are influenced by their fire residues after burning. This study uses intumescent/low-melting glass flame retardants to tailor fire residues in epoxy resin. Processibility of prepregs and their quality are analysed for transfer of the flame-retardant epoxy resins to layered glass-fiber reinforced composites. Minimal effects were found on the pre-fire flexural strengths of the composites due to low loading of the flame retardants. However, when transferred to glass-fiber reinforced composites, the fire residues diminish significantly. Further studies are required to improve theoretical and experimental estimations of the post-fire mechanics of the composites.
This study presents the processability, fire behavior, and mechanical performance between the flame retarded pure epoxy resin and flame retarded glass-fiber-reinforced plastic before, during, and after a fire event. This enables a deeper understanding of the transferability of flame retardants, modes of action, char enhancement, and flame inhibition on composite materials
Fire resistance of fiber-reinforced polymers (FRPs) has been an important area of research for many years since FRPs are mainly used in the transportation and construction sectors. This study presents the fire behavior, and mechanical performance between the flame retarded pure epoxy resin and flame retarded glass-fiber composites before, during, and after a fire event. This enables a deeper understanding of the transferability of flame retardants on composite materials.
