    摘要: The cut laminate edges of aircraft fuel tanks formed of carbon fiber reinforced polymers are sealed to prevent the exposure of carbon fibers to combustible fuel. The edge seal is produced from a prepreg form using a thermosetting resin matched to the characteristics of the resin used in the laminate. The prepreg form can be applied to the cut laminate edges either before or after the laminate is cured. The edge seal acts a dielectric layer that both electrically insulates the cut laminate edges from the fuel and mechanically contains energetic particles produced at the edges due to lighting strikes or other sources of electrical charges.
