Standard carbon epoxy absorbs moisture gradually under marine salt fog, which weakens interlayer shear strength over months. This version uses autoclave low-void substrate plus matched sealing coating to cap water ingress. We record water absorption rate and salt spray cycle data for each batch. It serves offshore inspection drone, coastal patrol equipment and marine sensor bracket. Full test report and COC can be provided for coastal region export clearance. Matte or gloss finish optional, CNC processing supported.
