The Saint-Gobain innovative Sandwich Radome was entered for a Combined Strength Award with our partner Ebert Composites Corporation and was chosen as a finalist at the Composites and Advanced Materials Expo (CAMX) recently held in Anaheim, CA USA. The award is for a product that demonstrates a team approach that brings together knowledge, resources, and talent to produce an incredible example of the best use of composite materials.
This radome product is designed specifically for use in protecting advanced weather, air traffic and air defense radar systems and is offered in sizes up to 68 ft. (21m) diameter. The Saint-Gobain Sandwich Radome combines our PTFE coated fabric technology with Ebert Composites Corp. thermoplastic forming and 3D insertion technology to produce a unique system that addresses current problems as defined by the industry. The construction of the panels for the large spherical domes prevent separation of the fiberglass based skins from the foam core which can result in catastrophic damage during high wind or heavy snow. The PTFE coated fabric used on the outer surface provides permanent hydrophobicity which optimizes transmission of radar signals through the dome in rain conditions without losing its properties through its 20 year design life. Additionally, the Saint-Gobain coated fabric outer surface dramatically reduces life cycle costs of the radome for the customer since it does not require expensive refurbishing to maintain performance.
The capital equipment for fabricating this breakthrough product has been installed at the PPL facility in Puyallup, WA and the coated fabric outer surface material is manufactured in Merrimack, NH.
