New Solutions For High Temperature Resin Transfer Molding Composites

 

 

Through five years of cooperation, the National Composites Centre (NCC) of the United Kingdom and Nexam Chemical of Sweden have achieved a major innovative breakthrough in resin transfer molding composite materials, providing a new solution for the manufacture of composite components in extreme high temperature environments.

 

Previously, resin transfer molding could usually only be carried out at about 120°C. NCC and Nexam Chemical have developed a new resin system NEXIMID that can operate at about 400°C, including unique mold design and high-temperature sealing technology. During the entire injection molding process, the temperature of the resin can be maintained above 250°C, which greatly improves the high-temperature performance of the resin and the high-temperature environment processing performance of the final composite product. At the same time, the new system will not release high concentrations of toxic gases like other polyimide resin systems.

 

Relevant personnel added that as one of the UK’s “High Value Manufacturing Catapult Centers”, NCC has achieved the manufacture of high-temperature resin-based composite materials based entirely on high-temperature resin systems produced in the UK. The excellent high-temperature performance of the new material enables it to adapt to more demanding application environments. Specifically, the industry can use the new material to process high-temperature heat-resistant components that could not be manufactured using composites before, such as engine parts, battery housings, etc.

 

Nexam Chemical recently joined the NCC as a small and medium enterprise affiliate member, paving the way for further cooperation on projects using high temperature resin transfer molding.
