EXAMINATION OF THE INFLUENCE OF SHEAR MICRO-GEOMETRICAL PROPERTIES ON TRANSVERSE ELASTICITY THE MODULUS OF ROVING COMPOSITE MATERIALS USED IN CRITICAL CONSTRUCTIONS

摘要

Monitoring of quality is an important task in the production process of critical supporting structures made from roving composites. Results from the research performed on the production samples of girders of helicopter blades presented in this paper, suggest that geometrical measures can be used for prediction of material strength and durability. The correlation between geometrical measurements of shear microstructure and values of the elasticity modulus determined in the transverse shear strength test by short beam method was assessed.
