Tow Preg - Preimpregnated Fibre Solutions.
About Tow Preg
Our Tow Preg solutions are advanced pre-impregnated fibre systems designed to deliver exceptional performance in modern composite manufacturing. By combining carefully engineered resin chemistry with precision-controlled fibre technology, our Tow Preg materials provide a reliable solution for winding, taping and targeted reinforcement within prepreg components.
Because of this unique combination, this enables engineers to design and manufacture lightweight, high-strength composite structures that perform consistently in the most demanding environments. In addition, these materials offer excellent process control, helping manufacturers achieve repeatable results across a wide range of applications, formats and environments.
High Performance
Our tailored epoxy systems are engineered to deliver strength, durability, and long-term reliability. As a result, these products are widely used in applications where mechanical performance and material stability are critical. Furthermore, the resin systems are designed to support efficient processing without compromising structural integrity.
Proven in Demanding Industries
These materials have been successfully used in pressure vessels, masts, flight vehicles and other advanced structural components. In these industries, performance demands are extremely high; therefore, manufacturers rely on this to ensure safety, strength and consistency. Over time, these products have proven their value in both commercial, high-performance and demanding engineering environments.
Versatile Applications
The material is suitable for a variety of composite manufacturing processes, including filament winding, taping, and localised reinforcement. In addition, it integrates seamlessly into existing prepreg workflows, giving engineers greater flexibility in design and production. Therefore, manufacturers can optimise structures for weight reduction while maintaining strength and durability.
Engineered for Precision and Reliability
Ultimately, the material provides a dependable solution for advanced composite applications where performance cannot be compromised. By delivering a balance of strength, processability, and versatility, it supports innovation in aerospace, defence, and industrial sectors.
