发明名称 '' FAVOS DE MEL, ARTIGO, ESTRUTURA AERODINÂMICA E PAINEL ''
摘要 <p>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.</p>
