STRIKEGRID® CEAF is a phosphoric acid anodized (PAA) continuous expanded aluminum foil (CEAF) product that also includes a proprietary coating which combines to negate the effects of galvanic corrosion when used in conjunction with carbon prepreg materials. STRIKEGRID® can be bonded to aircraft structures either as an outer ply or embedded ‘one-ply down’ beneath a layer of surfacing film.
