AI Technical Summary

Technical Problem

Conventional laminates used in interior trim elements of vehicles tend to splinter when broken, posing a risk of injury due to sharp-edged fragments, making them unsuitable for use in vehicle interiors despite their desirable properties like stability and aesthetic appeal.

Method used

A laminate with a flexible anti-shatter layer, typically a metal foil such as aluminum, is integrated between resin-impregnated paper layers to reduce splintering, enhancing the modulus of elasticity and breaking strength while maintaining visual appeal and load-bearing capabilities.

Benefits of technology

The laminate retains its shape under high force, preventing sharp-edged elements from breaking out and reducing material thickness, thus ensuring occupant safety and cost-effectiveness for use in vehicle interiors.

Abstract

The present invention relates to a laminate, more particularly for usage in interior trim elements of vehicles. The laminate comprises a first number of resin-impregnated paper layers (3a, 3b, 3c) and a second number of resin-impregnated paper layers (3a, 3b, 3c). Arranged between the first number of resin-impregnated paper layers (3a, 3b, 3c) and the second number of resin-impregnated paper layers (3a, 3b, 3c) is an anti-splinter layer (4).
