Honeycomb containing poly(paraphenylene terephthalamide) paper with aliphatic polyamide binder and articles made therefrom

This invention relates to a honeycomb having cells comprising a paper， the paper in one embodiment comprising 3 to 30 parts by weight aliphatic polyamide binder， and 70 to 97 parts by weight of a poly(paraphenylene terephthalamide) fiber having a modulus of 600 grams per denier (550 grams per dtex) or greater， based on the total amount of aliphatic polyamide binder and PPD-T fiber in the paper; and wherein the paper has an average specific tensile index of 60 (lbs/in)/opsy (310 Nm/g) or greater. In another embodiment， the honeycomb is made from a paper comprising 30 to 50 parts by weight aliphatic polyamide binder， and 50 to 70 parts by weight of a poly(paraphenylene terephthalamide) fiber having a modulus of 600 grams per denier (550 grams per dtex) or greater， based on the total amount of aliphatic polyamide binder and PPD-T fiber in the paper; and wherein the paper has an average specific tensile index of 60 (lbs/in)/opsy (310 Nm/g) or greater. Another embodiment includes articles comprising the aforesaid honeycombs， with such articles including a panel or an aerodynamic structure.
