HONEYCOMB FROM PAPER HAVING A HIGH MELT POINT THERMOPLASTIC FIBER |
摘要 |
This invention relates to a honeycomb comprising matrix resin and paper, the paper comprising 50 to 80 parts by weight fibrous material having a modulus of 600 grams per denier (550 grams per dtex) or greater, 0 to 50 parts by weight powdered inorganic material, and 20 parts by weight or greater thermoplastic fiber, the improvement comprising the thermoplastic fiber is a binder for the paper and has a melting temperature above the curing temperature of the matrix resin; a glass transition temperature of greater than 100°C, and the weight average molecular weight of the thermoplastic polymer in the thermoplastic fibers changes 20% or less after being maintained for 10 minutes at the melting temperature. One embodiment of this invention includes an article comprising the aforesaid honeycomb, with such articles including a panel or an aerodynamic structure. |
