Abstract: The invention relates to thermoplastic moulding compounds based on a heat-resistant plastic which contains, as filler, 0.5 to 50 % by weight of an oxide of an element from main group III to V, a salt of the oxo-acid of an element from main group III to V or a compound which forms an oxide or salt of this type when heated. The moulding compounds are suitable for the production of interior parts of passenger vehicles, in particular aircraft, of low smoke density and low heat output in the event of fire.

Abstract: Porous moulded sheet with density 0.2-0.8 kg/1 (I) is claimed, based on polyolefin (II) reinforced with fibrous mats consisting mainly of vegetable material (III). Also claimed is a process for producing (I), by impregnating (III) with molten (II), compacting under pressure to a density of more than 0.9 kg/1, cooling to below the m.pt. of (II), and then heating the semi-finished sheet to above the m.pt. of (II) without using pressure, to expand the sheet and reduce its density to below 0.8 kg/1. A blowing agent (IV) is added to (II) or (III) before impregnation. (I) contains 20-70 wt.% (III) in the form of needled mat based on sisal, coconut or banana fibres. (II) is polypropylene (PP) with MFI (230/2.16) = 5-500 g/10 mins.. USE/ADVANTAGE - Used for producing sound-absorbing parts for cars by deep-drawing or press-moulding (claimed). (I) offer a combination of good sound-insulating properties, high strength and toughness, and are cheaper than corresp. materials contg. glass fibreat

Abstract: A hybrid yarn has polyamide fibres with a filament dia. between 5 and 20 microns which are mixed with reinforcing fibres. The reinforcing fibres can be glass or C fibres. The yarn can be wrapped with a polyamide yarn. Also claimed are fabrics and consolidated composites using the hybrid yarn. Pref. four 1400 dtex polyamide yarns with 480 filaments (filaments 2.9 dtex. diameter 18.2 microns) and a 7200 dtex C fibre yarn with 12000 filaments (filaments 0.67 dtex. dia. 6.9 micorns) are taken over an air spreader and combined over two guides. The hybrid yarn is wrapped with a 6 tex polyamide with 12 filaments and treated with 0.6 size. A test piece is wound and pressed at 260 deg.C. The tensile strength is 47.0 MPa compared with the value of 27.4 MPa obtained when using conventional polaymide with 8.2 dtex filaments. USE/ADVANTAGE - Very fine polyamide fibres are used for improved composites for sports equipment, partic. tennis racquet frames.
