Global Composite Adhesive Market Trends

Automation in composite parts manufacturing: The rising use of automation technologies in composite parts manufacturing is having a significant impact on the global composite adhesive market. As automated production lines increasingly take over repetitive manufacturing tasks, the demand for adhesives optimized for machine dispensing and application is growing. Robotics enable much higher precision and consistency in adhesive application compared to manual methods. This is driving adhesive manufacturers to develop new formulations with precise flow properties and open times tailored for robotics. Adhesives requiring minimal specialized surface preparation or curing are especially attractive for automated composite fabrication.

The shift to automated manufacturing allows composite parts to be produced faster, cheaper, and with less variability compared to manual manufacturing. This expands the viable uses of composites into more cost-sensitive applications, such as automotive interior panels or wind turbine blades. As composite materials displace traditional materials in these growing markets, it greatly increases the addressable demand for composite adhesives. For instance, automakers in particular have strong incentives to use lightweight composite materials for vehicle weight reduction and are actively adopting new automated composite manufacturing technologies.

Rising Research & Development activities: by leading composite adhesive manufacturers is significantly impacting the global composite adhesive market. With continuous innovation and the development of new product varieties, companies are able to expand their portfolio and address the changing requirements of diverse end-use industries. Composite adhesive producers are focusing on developing adhesive solutions with improved bonding strength, heat resistance, longevity, and compatibility with various composite materials, such as carbon fibers, aramid fibers, and glass fibers. For instance, Henkel recently launched a new structural bonding adhesive under its Loctite brand for composite bonding applications in transportation industry. This adhesive has been engineered to deliver high strength and durable bonds for composite components exposed to demanding temperatures up to 180 degree sCelsius. Similarly, Sika has come up with an epoxy-based adhesive for wind turbine blade fabrication. According to company studies, this adhesive results in reduced curing time and higher production output for blade manufacturers compared to conventional polyurethane adhesives.
