Title: NOVEL DIELECTRIC POLYMER MATERIALS FOR PLASTIC AND COMPOSITE APPLICATIONS
Abstract: Plastic and composites are typically designed for mechanical and possibly thermal performance, but insufficient consideration is provided for electrically designed applications. As composite requirements become more complex with structural and environmental concerns, the ability to identify solutions for complex electrical and electronic applications becomes much harder. The availability of a family of controlled dielectric materials that can be utilized in many plastic and composites applications would be of great value to the design community. ARC Technologies has developed a new family of dielectric controlled polymeric materials for injection molding, thermoforming and composite applications. The material includes formulations with a wide variety of electrical properties. Included are low dielectric, low-loss that are ideal for applications from 2.6 GHz to 77 GHz, including radomes for automotive radar, and can be used as an impedance-matching material or as a dielectric spacer. Another formulation is a highly conductive plastic that provides excellent shielding over a wide frequency range, and is an ideal material for molding electronic covers and enclosures that can benefit from low cost and design flexibility. A third formulation is a magnetic absorber that provides a balance of mechanical and electrical properties. It is ideal for surface current reduction, cavity mode suppression, and attenuating near-field emissions from 1 to 18 GHz. This paper will provide detailed mechanical and electrical properties of the new materials, along with processing methodologies, including incorporation into composite structures. Examples of components manufactured with the materials will also be provided.
