摘要: This study investigates the simultaneous use of conventional fire-retardant additives and an insulative intumescent thermal barrier/mat to improve fire performance mechanical property retention glass-fibre-reinforced polyester (GRP) composites. Significant reductions in peak heat release rate (PHRR) total (THR) were observed from measured cone calorimetric data following addition nitrogen, phosphorous, halogen containing hydroxylated additives. Some fire-retarded composites further protected by mat silicate fibres, expandable graphite borosilicate glass bound together organic matrix show PHRR. Despite improving retardancy composites, presence alone does not flexural modulus exposure a source. However, introduction 'passive' proofing fabric enhances while preserving properties exposed high fluxes or fires.
