Lightning strike specialist Dexmet's (Wallingford, Conn., USA) expanded lightning strike division will is offering MicroGrid precision, expanded metal foils to makers of composite materials for lightning strike protection. MicroGrid's single unit structure is said to be superior to woven material in that it won't unravel or produce loose strands that become problematic during processing into a pre-preg material or when conducting a dry lay-up. The homogenous design also reportedly ensures uncompromised conductivity between strands when forming the material to a variety of shapes and contours, and provides a smooth surface on the end product. Dexmet says the biggest advantage of MicroGrid is the company's ability to tightly control the manufacturing process to meet a specific weight, open area and conductivity requirement. Dexmet says its precision expanded metals and polymers allow engineers the option of varying materials according to specific strike zones on the aircraft or structure, while adding little weight to the aircraft or structure. Also, printed copies of Dexmet's 12-page technical papers will be available at the booth.
