Optimization of Carbon Fiber Reinforced Plastic Curing Parameters for Aerospace Application

The use of carbon fiber reinforced plastic (CFRP) is increasing in engineering applications such as aerospace, automobiles, defense, and construction. Excellent strength-to-weight ratio, high impact toughness, corrosion resistance make CFRP highly suitable for aerospace applications. Curing temperature, curing time, autoclave pressure are among the most important parameters affecting properties CFRP. Tensile strength, hardness were selected desirable optimization. A 23 full factorial design experiment (DOE) was employed by varying temperature (120 140 °C), time (90 120 min), (3 7 bar) while keeping number experiments to a minimum level. cured samples subjected tensile tests at room per relevant ASTM standards. Analysis variance (ANOVA) used, it found that influenced significantly time. maximum strength achieved cycle °C, min, bar, toughness maximized 3 bar. concept composite desirability function used achieve simultaneous optimization conflicting specific application aircraft skin.
