Thermoplastic composite and multilayer pipe made of it

Opísaný je termoplastický kompozit z kopolyméru vinylacetátu a vinylalkoholu s etylénom s anorganickými plnivami a/alebo výstužami, ktorý obsahuje 3 až 15 % hmotnostných uhlíkového vlákna a až do 9,9 % hmotnostných čadičového vlákna. Opísaná je tiež viacvrstvová rúrka, kde aspoň jedna vrstva je z termoplastického kompozitu. The utility model relates to a thermoplastic composite of a copolymer of vinyl acetate and ethylene vinyl alcohol with inorganic fillers and/or reinforcing components, characterized in that it contains 3-15 wt. % carbon fibers, from 0 to 9.9 basalt fiber and from 15 wt. % to 35 wt. % binders, where the carbon fibers can be cut or ground. The binders are based on polypropylene and its copolymers with ethylene and polar co-monomers. The utility model also relates to multilayer pipes in which at least one layer is produced from the disclosed thermoplastic composite. An advantage of the described thermoplastic composite is that it has a reduced coefficient of linear thermal expansion.
