Thermal degradation and pyrolysis kinetic behaviour of glass fibre-reinforced thermoplastic resin by TG-FTIR, Py-GC/MS, linear and nonlinear isoconversional models

Recently, global demand for glass fibre-reinforced thermoplastic (GFRP) composites and their applications in the production of wind turbine blades has increased due to their bigger strength, impact resistance, toughness, etc. compared to thermosetting resin. In this work, the thermal degradation and...
