Renegade Materials earns NCAMP certification for low-dielectric prepreg

Renegade Materials (Miamisburg, Ohio, U.S.), a global provider of aerospace composite materials and a subsidiary of Teijin Holdings USA Inc., a member of the Teijin Group, announces National Center for Advanced Materials Performance (NCAMP) qualification of the company’s high-performance low-dielectric prepreg material, made by impregnating woven quartz fabric with epoxy resin. The development and execution of the test plan was completed in under 12 months.

Renegade Materials’ RM-2014-LDk-Tk-4581 prepreg has successfully completed qualification and design property testing through Wichita State University’s (WSU) National Institute for Aviation Research (NIAR), enabling it to be listed in the NCAMP database and CMH-17. This data is vital for accelerating the adoption of composite material systems for aircraft manufacturers, ultimately reducing production costs and enabling rapid transition to production.

These materials are used for aircraft radar domes (radomes) as they provide optimal electrical insulation and enhanced signal integrity, but also has value-added capabilities such as reducing electromagnetic interference (EMI).

The RM-2014-LDk-Tk prepreg system is part of a suite of compatible low-dielectric products offered by Renegade Materials, including prepregs on quartz, glass, peel plies, syntactic foams and low dielectric adhesive. B-Basis design allowables are now available for 4581-style quartz in the statistical analysis report. Dielectric properties (X-band) are available alongside mechanical properties. Prepreg is available under the NMS201/1 NCAMP material specification.
