Study on the Fuel Resistance of J-190 Polymer Filling Material

A series of tests were carried out,including the compatibility of J-190 filling material and HM109-1 sealant,the compatibility of J-190 filling material and anodized aluminum alloy,the compatibility of J-190 filling material and S06-0215 primer,the fuel and salt water two-layer liquid resistance of J-190 filling material,and fuel resistance of J-190 filling material.The test results showed that J-190 polymer filling material could meet the requirement of designs.
