| This chapter discusses a problem of parameterization of irregular reinforcement distribution in uniaxial fiber-reinforced composites (CFRC) expressed as an area ratio of the matrix surrounding a single fiber to its perimeter. The distribution parameter, GAB, was applied in the analysis of possible relationships between the microgeometry and mechanical properties of glass-epoxy composites with random distribution of continuous fibers. Test specimens were made in a repeatable process production of the girders of helicopter blades and were tested in bending during the short beam shear tests (SBST), as well as their basic mechanical properties (e.g., the flexural modulus Ef, taking into account shear effects) were determined. The relationship between the SBST results and the theoretical topology of regular CFRC structures was presented: the square (K) and the hexagonal (H) type. The K theoretical model of fiber distribution corresponded with experimental results. It was concluded that the measure of irregular reinforcement distribution (GAB) could be used to estimate the flexural elastic modulus Ef of unidirectional CFRC composites. |
