Effect Of Mineral Fillers On The Compressive Strength Of Glass Reinforced Plastic Composite

The Glass Reinforced Piastic (GRP) coroposite mat~rials were made- by simple hand l~y-up technology (open-mould 'process) '(>'hereby Calcium .. Carbonate and Talc mineral fillers were added each in the following proportions: 5%, 1 0%, 15%, 20% and 25%. The materials were tested for compression strength, since the material is intend{3d -to be used in construction industry especially in cladding p~nel form.
