Abstract: The paper analyzes the results of static tests conducted on fibrous composites. The strength characteristics were obtained
for samples of different measuring length and different reinforcement architecture, produced by vacuum bag moulding and
contact moulding using UDO E-type unidirectional fibreglass fabric as the reinforcement and HAVEL pol.2 polyester or LH
160 epoxy as the matrix. Then, the experimental data were analyzed by applying advanced statistical apparatus to verify the
assumptions about the normal and logarithmic-normal distributions of strength. The statistical analysis is essential to correctly develop a model to determine the strength characteristics of fibrous composites based on the Markov chain theory.
