The study deals with the chemical and flame retardant (FR) treatment of woven flax fabric and preparation and characterization of flax reinforced phenolic composites. Sheets of flax fabric were subjected to chemical treatments using NaOH and silane coupling agents. A phosphate-based flame retardant (DAP) was applied to decrease the flammability of the flax fabric. The effect of the chemical treatments and FR treatments on the thermal and flammability properties of the fabric and composites was investigated using thermogravimetric analysis (TGA), vertical flame resistance test and cone calorimeter. The mechanical properties of the flax fabric and composites, before and after environmental ageing, were investigated. Ageing studies were carried out by exposing the samples in an environmental chamber at specified conditions for two weeks. TGA results showed that the treatment of the fabric with FR shifts the decomposition temperature to lower level and increases the char residue. Vertical flame resistance testing showed that FR treatment of the flax fabric improved the flammability properties. There was no after flame and afterglow observed for FR treated flax fabric due to self-extinguishment after removal of the flame. Flax Fabric without FR burned completely and there was no result for the char length due to the complete destruction of the fabric. The FR treatment, however, seemed to have had a negative effect on the tensile strength of the flax fabric. This was further intensified upon exposure of FR treated flax fabric to high temperatures during ageing studies which drastically reduced the tensile strength by more than 90%, and the flax fabric were found to be brittle and darker in visual appearance. TGA results of flax/phenolic composites showed that for composites containing chemically treated and FR treated flax fabric the decomposition temperatures shifted to lower temperatures; however there was no significant difference in the amount of char residue. Untreated flax/phenolic composites exhibited the lowest char residue. Cone calorimeter results showed that the peak heat release rate (PHRR), smoke production rate (SPR) and carbon dioxide (CO2) emission rate was reduced for the flax/phenolic composite produced using FR treated flax fabric. The tensile strength of these composites was reduced while there was an increase in modulus value. Exposure of the FR treated composites to high temperatures further reduced the tensile strength and increased the E-modulus. Both FR treated and untreated composites changed in colour and the FR treated composites were found to be brittle after exposure to high temperatures.
