In the field of high-performance materials, few innovations offer as much potential as prepreg composite technology. Led by the Connova Group, this cutting-edge technology uses pre-impregnated fibres encapsulated in a partially cured polymer matrix to produce components that are not only lightweight but also exceptionally strong and durable.
What is a prepreg composite?
Prepreg, short for “pre-impregnated” fibres, consists of continuous fibres – either unidirectional, woven or non-woven – impregnated in a thermoset polymer matrix that is not yet fully cured. This unique configuration allows precise control over fibre orientation and volume content, resulting in materials with low porosity, high surface quality and excellent temperature resistance.
The process and advantages of prepreg autoclave technology
Connova Group utilises an advanced autoclave process to cure these materials under high pressure and temperature, a process that typically takes 4 to 7 hours depending on material type and component size. The autoclave technology not only enables well-defined fibre alignment – crucial for achieving the desired mechanical properties such as elasticity or stiffness – but also ensures a high-quality, consistent material with excellent fibre-to-fibre force transfer.
This process offers several advantages:
Applications in various industries
Connova Group’s prepreg autoclave technology is used in various industries with high demands. From aerospace, where it is used for fuselage and wing structures, to motor racing, where the strength-to-weight ratio offers significant performance benefits. In addition, the technology is used in the manufacture of high-performance parts for yachting, aerospace and even medical devices such as X-ray transparent patient beds.
Expertise and infrastructure
The Connova Group has established a robust infrastructure to support its advanced manufacturing processes. This includes temperature-resistant moulds, computer-controlled autoclaves that can accommodate large components and CNC machining centres for precise finishing. Their facilities also have controlled environments to prevent any contamination during the lamination process, ensuring the highest quality standards are maintained.
Commitment to innovation
Connova doesn’t just manufacture components; they are deeply involved in the engineering and development of customised solutions tailored to the specific needs of their customers. With decades of experience and a commitment to quality evidenced by ISO EN9100 and EN9001 certifications, Connova is a leader in the composites industry, constantly pushing the boundaries of what is possible with materials science.
Outlook
As industries continue to seek lighter, more efficient materials that do not sacrifice strength or integrity, Connova Group is positioning itself at the forefront of the composites field with its expertise in prepreg autoclave technology. With ongoing investment in research and development, Connova remains dedicated to advancing these materials for future applications and promises new ways to innovate in sectors as diverse as aerospace, automotive and beyond.
Through its comprehensive approach, from concept to production, Connova ensures that each project not only meets the exact requirements of modern engineering challenges but even exceeds them, demonstrating the transformative potential of prepreg composite materials in shaping the future of materials science.
