LaminaHeat LLC (Greenville, S.C., USA) has introduced PowerFilm, which is made from a very thin, flexible, lightweight and homogeneous carbon fiber/polymer sheet with copper contact strips that enable current to be applied to generate evenly distributed and localized heat across the fiber/polymer sheet at temperatures up to 450°F/232°C. PowerFilm can employ several polymer and finishing options that offers manufacturers the ability to physically laminate PowerFilm into products during fabrication, or simply add PowerFilm to existing applications. It can be incorporated directly into finished parts or manufacturing tooling, or it can be supplied from LaminaHeat already encapsulated in silicon rubber (PowerBlanket) or a fiberglass/resin matrix (PowerPanel) for use as a heating element/tooling in composite fabrication and vacuum bagging processes where the high cost of ovens or autoclaves may be prohibitive. LaminaHeat specifications can be adjusted to meet the needs of the electrical properties required. It comes in continuous rolls or in individual sheets in three standard width options and can be tailored to fit specific applications and/or resin systems as needed.
