Method and apparatus for measuring the elasticity of materials for lining vehicle components

摘要

The invention relates to a non-destructive method for measuring the elasticity of templates of materials for lining automotive vehicle components, characterized in that it comprises the following steps: applying a tensile pre-load with a predetermined value Pl in a longitudinal direction to a template section (41); applying a tensile load with a predetermined value P2 in a longitudinal direction to said section (41) and measuring the longitudinal deformation produced; removing the load applied to said section (41) and measuring the residual longitudinal deformation produced. The invention also comprises an apparatus (11) for carrying ouL Lhe method which comprises two fixing elements (15, 17) for fixing the section (41), one of which elements is a fixed element (15) and the other is a moving element (17), a device for applying a tensile load to the moving element (17) connected to a dynamometer (29), and a rule (31) for measuring the longitudinal deformation of said section (41).
