<p>An aramid honeycomb core board made of para-aramid fiber paper and preparation method thereof. The aramid fiber paper consists of the following fibers: structural fiber 20% to 75% by weight, and bonding fiber 25% to 85% by weight, the structural fiber being polyphenylene terephthalamide fiber, and the bonding fiber being polyphenylene terephthalamide fibrid. The aramid honeycomb core board has excellent modulus of compressibility and shear modulus, and can be widely applied in the aviation, aeronautical, military, electronics, and mechanical industries.</p> |
