FOLDED CORE BASED ON CARBON FIBER PAPER AND ARTICLES MADE FROM SAME
摘要
This invention relates to a folded core structure made from paper comprising 20-85 weight percent of carbon fiber floc. The carbon fibers have a non-circular cross sectional aspect ratio of at least 1.5:1. The paper has a fiber volume fraction of at least 35%. The arithmetic mean length of the carbon fibers is at least 0.5 mm. and length weighted mean length at least 0.9 mm.
