| 摘要 |
The present invention relates to a multilayer composite. The multilayer composite comprises: a first layer (layer I) including 40 wt% or more of a molding mixture including 1) copolyamide having 60-99 parts by weight of hexamethylenediamine, terephthalic acid, and aliphatic dicarboxylic acid having 8-19 carbon atoms as a substrate, and 2) 40-1 parts by weight of an olefinic copolymer as an impact modifier; and a second layer (layer II) including a molding mixture including 60 wt% or more of a fluoropolymer. The sum of parts by weight of the 1) component and parts by weight of the 2) component is 100. The multilayer composite has high thermal deformation temperature, remarkably excellent impact resistance, high fracture elongation, and excellent layer adhesive strength. |
