With advanced processing technologies such as RTM, HP-RTM, vacuum infusion, and integrated resin dosing systems, thermosets remain a scalable and future-ready solution for demanding structural performance.

A cross-sector exploration
Thermoset composites remain the backbone of many large-scale structural applications. Their combination of high mechanical performance, chemical resistance, thermal stability, and design
flexibility makes them indispensable when reliability and long service life are non-negotiable.
From RTM and HP-RTM to vacuum infusion, wet compression molding, and reaction injection molding, thermosets can be tailored to meet vastly different structural and production requirements. This adaptability allows manufacturers to scale from low-volume, highly engineered parts to high-volume industrial production — when supported by the right processing technology.
Aerospace: Qualified performance and process control
In aerospace, thermoset composites retain a dominant position in both primary and secondary structures. Epoxy and prepregs, along with RTM components, are favored for their behavior, qualification history, and predictable long-term performance.
Aerospace manufacturing places extreme emphasis on process control, repeatability, and
material traceability. Precision dosing, mixing, and resin conditioning systems — core
competencies for Cannon — support production processes by ensuring consistent resin quality and strict adherence to process windows. With patented solutions like the Dynamic
Overpacking System (DOS), Triple Vacuum Frame (TVF), and in-line degassing, processing thermosets becomes easier, more reliable, and produces a higher quality product.
Wind energy: Large structures, long-term reliability
The wind energy industry relies heavily on thermoset composites for blades, spars, and load-bearing structures. These components require long fiber lengths, excellent fatigue resistance, and predictable mechanical behavior over decades of service.
Vacuum infusion, light-RTM, and wet compression molding remain central to wind blade
manufacturing, while resin handling and delivery become as critical as mold design. Advanced dosing equipment, in-line degassing, and temperature control systems — like those we have developed for large composite structures — help ensure uniform fiber wet-out, reduced void content, and repeatable quality across increasingly large and complex parts.
Automotive: Structural performance at production volumes
In the automotive sector, thermosets are widely used for structural reinforcements, battery
enclosures, underbody shields, and body-in-white components. These applications demand high stiffness, controlled energy absorption, dimensional stability, and resistance to heat and chemicals, especially for EVs.
HP-RTM and S-RIM enable thermosets to reach high production volumes but require precise resin metering, repeatable injection, and tightly controlled curing — areas where integrated processing solutions play a critical role. Cannon, as specialists in reactive polymers and composite processing systems, support automotive manufacturers with complete and integrated turnkey production plants designed for structural thermoset applications.
Proven today — and ready for the future
While new materials and hybrid solutions continue to emerge, thermoset composites remain proven, scalable, and trusted for structural applications across industries. Their continued
success is driven not only by material performance, but by advances in processing technology, automation, and system integration.
