Composites

Flame resistant composites and nanocomposites

“…Hence, these are used in the form of single-thickness, parallel-laid, pre-impregnated sheets or narrow continuous tapes. 1 Their main advantages are high stiffness and compression strength, but they are rather expensive. Their ability to withstand working temperatures as high as 350 ° C for their whole expected service lives is a signifi cant factor in their selection for high temperature applications.…”

“…32 In our earlier review, we considered the potential for inclusion of intumescents within the composite structure and noted at that time (2001), very little interest had been shown. 1 Kovlar 33 in 1993 reported using an intumescent component as an additive in a phenolic matrix in which, upon exposure to fi re, the intumescent composite formed an expanded but tough, insulating, fabric-reinforced carbonaceous char that blocked the spread of fi re and insulated adjacent areas from the intense heat.…”

Review of Smoke Toxicity of Fiber-Polymer Composites Used in Aircraft

“…A large amount of data has been published on the concentrations of CO and CO 2 inside the smoke plume of composite materials [4,6,7,9,14,19,[40][41][42][43]. The yields of CO and CO 2 gases from a wide variety of aerospace composite materials with thermoset (e.g., epoxy, phenolic, bismaleimide, phthalonitrile) or thermoplastic matrix [e.g., PEEK and polyphenylene sulphide (PPS)] composites have been determined for a range of fire test conditions.…”

Health Hazards of Composites in Fire

“…epoxy, polyester, phenolic, BMI, phthalonitrile) or thermoplastic matrix (eg. PEEK, PPS) composites have been determined for a range of fire test conditions [29][30][31][32][33][34][35][36][37]. The formation of these gases during the decomposition of composites containing combustible organic fibres has also been studied [32].…”
