Unlike steel, which has uniform properties in all directions (isotropic), GRP is anisotropic. Its strength depends entirely on the orientation and quantity of the glass fibers. BS 4994 addresses this by calculating properties based on the weight of glass per unit area, rather than total laminate thickness. 2. Factor of Safety ( The standard calculates a global design factor (
