However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilising and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

180+ innovations will shape the aerospace and defence industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the aerospace and defence industry using innovation intensity models built on over 262,000 patents, there are 180+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, bonded fibre laminates, thermoplastic elastomer laminates, and vibration supression devices are disruptive technologies that are in the early stages of application and should be tracked closely. Centrifugal fan impellers, ceramic composite laminates, and gas turbine engine testing are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are protective blade coatings and blade alloy welding, which are now well established in the industry. 

Innovation S-curve for the aerospace and defence industry

Epoxy prepregs is a key innovation area in aerospace and defence

Prepreg is a reinforcing fabric with resin that includes a proper curing agent and can be laid into a mould without the need for more resin. Prepreg is a semi-finished product for making fibreglass reinforced plastic (FRP) products.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 10+ companies, spanning technology vendors, established aerospace and defence companies, and up-and-coming start-ups engaged in the development and application of epoxy prepregs.
