The increasing presence of carbon fiber composites in manufacturing is driving the need for dielectric cure monitoring during the manufacturing process. Normally, dielectric sensors require filters to block conductive fibers 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 cure monitoring without filters, for seamless integration into molding 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 user defined end of cure.
