Abstract
Overview
ISO 7822:1990 specifies three calibrated laboratory methods for determining the void content (void fraction) of textile glass reinforced plastics (glass-fibre reinforced composites whose constituents are solids). The standard covers sample preparation, required apparatus, test procedures, calculation of void content (expressed as % by volume), and reporting requirements. It is intended for quality control, materials characterization and comparative testing of composite parts and laminates.
