FIELD: transport.;SUBSTANCE: invention relates to hybrid parts or low-weight parts with cavities consisting of cup-like base reinforced by thermoplastic materials. The latter contain 10-99.99 wt % of, at least, one partially crystalline thermoplastic polymer and 0.01-50 wt % of, at least, one olefin copolimerisate with one ether of methacrylic acid or ether of acrylic acid of aliphatic alcohol. Fluidity index of copolimerisate melt makes, at least, 100 g/10 min.;EFFECT: higher breaking strength, hardness and durability.;4 cl, 3 dwg, 4 tbl, 4 ex
