The invention relates to a seal for an aircraft incorporating a fire-resistant structure, and an aircraft incorporating at least one such a seal between structural elements of the aircraft connected to each other at a zone of the latter which may be a fire zone according to the standard ISO 2685:1998 or AC 20-135.

According to the invention, this seal (10) comprises: a seal body (11) at least partially elastomeric, the seal body defining at least one generally tubular or annular cavity (10A), and a fire-resistant structure (12) distinct from the seal body and disposed inside the cavity, the fire-resistant structure comprising an intumescent mass able to fill the cavity (10A) in an expanded state,
the intumescent mass being made of a rubber composition having an intumescence trigger temperature equal to or higher than 270° C., measured by a plane-plane rotary rheometer with a temperature scan from 23 to 380° C. according to a ramp of 10° C./min.

A method of producing, from a continuous or discontinuous (e.g., chopped) carbon fiber, partially to fully converted metal carbide fibers. The method comprises reacting a carbon fiber material with at least one of a metal or metal oxide source material at a temperature greater than a melting temperature of the metal or metal oxide source material (e.g., where practical, at a temperature greater than the vaporization temperature of the metal or metal oxide source material). Additional methods, various forms of carbon fiber, metal carbide fibers, and articles including the metal carbide fibers are also disclosed.

An organic-inorganic composite including: a plurality of anisotropic ceramic particles having different aspect ratios; a resin that is combined with the ceramic particles; and a plurality of projections projecting out from the surface of the ceramic particles, thereby increasing the shear resistance of the interface between the ceramic particles and the resin. At least some of the ceramic particles neighboring each other are closely arranged such that the projections partially contact each other, thereby increasing the shear resistance between the ceramic particles due to the contacting ceramic particles.

A curable polymer composition containing: (A) a thermoset benzoxazine resin precursor component; (B) optionally, an aryl sulphone-containing benzoxazine component, and (C) a polyarylsulphone thermoplastic toughening agent, wherein in the absence of component (B), component (C) contains one or more benzoxazine pendant- and/or end-groups.
