Composites monitoring


Lambient Technologies LLC, a leader in analytical solutions for the curing of advanced polymer materials, has announced the launch of Carbon+™ for use with carbon fibre composites.

The increasing presence of carbon fibre composites in manufacturing is driving the need for dielectric cure monitoring during the manufacturing process. Normally, dielectric sensors require filters to block conductive fibres and prevent short-circuiting of the electrodes. Filters must be replaced manually after each test and their use adds time, effort and cost, so it is necessary to avoid using them in rapid, repetitive operations.

Carbon+ direct contact sensors from Lambient Technologies have a protective, permanent insulating layer that allows for cure monitoring without filters, for seamless integration into moulding applications. The data from Carbon+ sensors show a consistent relationship with cure state and can be used to determine flow front or resin contact, minimum viscosity point, time-of-peak reaction rate, which may be associated with gelation, and a user-defined end of cure.

Lambient Technologies designs and produces instruments for real-time analysis of the curing of thermosets and advanced composite materials, such as those used in aerospace, automotive and wind power applications. The products offer a unique insight into how these materials react and change during curing, processing and manufacturing. Armed with this critical data, users can proceed with research, quality testing and final production, confident in the integrity of their processes and materials and the reliability of their finished products.
