LIGHT COMPOSITE THERMOPLASTIC SHEETS, CONTAINING REINFORCEMENT SHELL Russian patent published in 2011 - IPC B32B27/12 B32B27/02 B32B19/02 C08J5/18 B29C43/28 B60N2/00 

FIELD: construction.

SUBSTANCE: sheet includes, in standard version, a permeable fibre-reinforced thermoplastic middle layer, having the first surface and the second surface. The middle layer includes structures with open cells, formed by accidental weaving of multiple reinforcing fibres, having the average length approximately from 5 to 50 mm and attached to each other by thermoplastic resin, having density approximately from 0.1 g/cm³ to 1.8 g/cm³, content of cavities is approximately between 1 and 95%, and approximately 20-80 wt % of fully or mostly noncompacted fibres or particles of thermoplastic materials. The multilayer sheet also includes at least one first reinforcement shell on the first surface of the middle layer, and at least one second reinforcement shell on the second surface of the middle layer. Each first and each second reinforcement shell includes a matrix of reinforcement fibres and thermoplastic resin, where reinforcement fibres of the matrix on the first surface, and reinforcement fibres of the matrix on the second surface are aligned in two directions. The structural component of a vehicle interior includes a seat back of the specified multilayer fibre-reinforced material.

EFFECT: increased operational reliability.
