TL;DR: In this paper, extensive test results of linear elastic mechanical properties of Nomex paper and nomex honeycomb structures are presented, which are then used in the finite element modeling and analysis of NOMEX honeycomb structure.
TL;DR: In this article, the authors investigated the damage behavior of composite sandwich panels with aramid paper honeycomb (NOMEX) and polyetherimide (PEI) foam cores under transverse impacts at high velocities.
TL;DR: Chlorination of poly(m-phenyleneisophthalamide) and poly(p-phenyleneterephthalamide) (Kevlar) fabrics by sodium hypochlorite aqueous solution was investigated as mentioned in this paper.
Abstract: Chlorination of poly(m-phenyleneisophthalamide) (Nomex) and poly(p-phenyleneterephthalamide) (Kevlar) fabrics by sodium hypochlorite aqueous solution was investigated. Results indicated that stable N-halamine structures could be readily formed in Nomex, which provided potent, durable, and refreshable antibacterial functions against both Gram-negative and Gram-positive bacteria. However, similar chlorination treatment of Kevlar led to serious hydrolysis of the polymer. The treated fabrics were fully characterized by Fourier trasnform infrared, thermal, and X-ray diffraction studies. Possible mechanisms of this effect were discussed.
TL;DR: In this paper, the preparation of activated carbon fibers (ACFs) by phosphoric acid activation of Nomex [poly(m-phenylene isophthalamide)] polyaramid fibers was studied.
TL;DR: In this article, a nonwoven textile panel for use as a fire retardant and sound deadening barrier in the interiors of aircraft, comprised of three layers of non-oven textile fibers of polyphenylene sulfide fibers and Nomex brand aramid fibers that have been carded, cross-lapped, needle punched and thermally bonded by heating the panel to the temperature softening point of the PLS fibers.
Abstract: A nonwoven textile panel for use as a fire retardant and sound deadening barrier in the interiors of aircraft, comprised of three layers of nonwoven textile fibers of polyphenylene sulfide fibers and Nomex brand aramid fibers that have been carded, cross-lapped, needle punched and thermally bonded by heating the panel to the temperature softening point of the polyphenylene sulfide fibers. The fibers are capable of being thermoformed and retaining a permanent shape due to the thermoplastic properties of the polyphenylene sulfide fibers.
