20130136911	FLAME-RETARDANT POLYMER FIBRES AND USE THEREOF AND TEXTILE FABRIC COMPRISING THESE POLYMER FIBRES - The flame-retardant polymer fibre according to the invention comprises a PA66/PA6 polymer blend having the following composition: 60 to 90% by weight of polyamide 66, 6 to 25% by weight of polyamide 6, 4 to 10% by weight of at least one halogen-free flame retardant made of a polycondensate of a) at least one phosphorus-containing monomer selected from adducts of a1) 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and/or nuclear-substitution DOPO derivatives in a2) unsaturated compounds from the group of mono- and multivalent carboxylic acids and the anhydrides thereof and b) at least one ester-forming monomer selected from the group of mono- or multivalent alcohols and mixtures thereof. In addition to the flammability resistance, the polymer fibre according to the invention has very good textile-mechanical properties, and is resistant to washing-out of the flame retardant.	05-30-2013

20130225721	FIBER STRUCTURE, METHOD FOR ITS MANUFACTURE AND USE AS WELL AS FIBER-RESIN COMPOSITE MATERIAL - The invention relates to a fixed and/or stabilized fiber structure from a fibrous material as well as from an agent for its fixing and stabilizing. The agent for fixing and stabilizing is a statistical copolyester which is formed from the diacid components terepththalic acid and, optionally, isophthalic acid as well as the diol components butanediol, diethylene glycol and triethylene glycol. A method of manufacturing this fiber structure is also provided. The fiber structure is used as a reinforcement material for polymer matrices, in particular epoxy resins. A fiber composite material containing at least one thermosetting resin as well as the fiber structure in accordance with the invention is furthermore provided.	08-29-2013
