Wing is a crucial airframe material which produces lift heavier than aircraft. The design of wing depends on many factors like size, speed, and weight. Improving the fuel efficiency is the prime objective of aircraft industry which can be achieved by using lightweight materials. The conventional materials like Al alloys and epoxy-carbon fiber composites reduced the weight of aircraft and improve the fuel efficiency. However, the high density of aluminum alloys compared to polymers limits and epoxy-CF’s ability to absorb moisture are some of the limitations of the present materials used in the aircraft wing. Recent investigations and development of high-performance polymers like PEEK-CF composite’s low density compared to aluminum and its moisture-repelling properties, good chemical, and abrasion resistance with improved mechanical properties are becoming an attractive alternative for current materials used in aircraft industry. The present paper aims at design and analysis of a trainer aircraft’s wing by replacing the Al and epoxy-carbon fiber composites with PEEK-CF composites. The results showed that PEEK-CF composite showed less deformation and high frequencies while the stress values obtained are very close to Al7075T6 and epoxy-CF used thus gaining its prominence as an attractive alternative for the present materials used in industry.
