Method for manufacturing multilayered fiber-thermoplastic-laminar structure material of auto body device of motor vehicle, involves forming foils by side of composite material whose thermal expansion coefficient is less than specific value

摘要

The method involves arranging thermoplastic foils (11) and a fibrous material such that a multi-layer structure is provided with the foils and a fiber layer (21). One of the outer sides (10) of a composite material is formed by the foils, and the fiber layer is arranged between the foils. A multilayered fiber-thermoplastic-laminar structure material (1) is manufactured from the multi-layer structure of the foils and the fibrous material. The outer side of the composite material forming thermoplastic foils has a thermal expansion coefficient that is less than 70 x 10 ->6 1 >K. Independent claims are also included for the following: (1) a multilayered fiber-thermoplastic-laminar structure material including thermoplastic foils (2) a method for manufacturing a device i.e. auto body device.
