Dumitru Bolcu, Marius Marinel Stanescu, Ion Ciuca, Sorin Dumitru, Mihaela Sava The Non-uniformity from the Composite Materials Reinforced with Fiber Glass Fabric


Abstract:
In this paper we study the non-uniformity that appears in the composite bars reinforced with fiber glass fabric. We defined a factor which characterizes the non-uniformity from the composite materials. We will give a formula for calculating this coefficient and a formula for the elasticity modulus of the composite bars, with two zones in which the volumetric proportions of reinforcement are different. We compared the theoretical results, which give the values of the uniformity coefficient and elasticity modulus, with experimental results obtained for three sets of samples made from ambresit and reinforced with fiber glass fabric. Keywords: composite materials, non-uniformity coefficient, elasticity modulus
