Abstract:
This invention relates to a honeycomb having cells of paper, comprising by weight 3 to 30 parts by weight aliphatic polyamide binder, and 70 to 97 parts of a poly(paraphenylene terephthalamide) fiber having a modulus of 600 grams per denier (550 grams per dtex) or greater, based on the aliphatic polyamide binder and PPD-T fiber in the paper. In another embodiment, the honeycomb is made from paper comprising by weight 30 to 50 parts aliphatic polyamide binder, and 50 to 70 parts of a poly(paraphenylene terephthalamide) fiber having a modulus of 600 grams per denier (550 grams per dtex) or greater, based on the aliphatic polyamide binder and PPD-T fiber in the paper. Both papers have an average specific tensile index of 60 (lbs/in)/opsy (310 Nm/g) or greater. Articles made from the honeycombs include a panel or an aerodynamic structure.
