Abstract


In this paper is carried out the comparative analysis of effectiveness of test methods ofdetermination of stiffness and strength properties of highly filled unidirectional fiberglass (Direct "E" roving 0.7- orthophthalic polyester resin 0.3) via tensile testing along the reinforcement and three-point bending testing atseveral bases. The necessity of deviation from standard procedures is substantiated. Deformation and failurefeatures of the material under quasi-static loading, as well as at low and high temperatures, are shown.
