Abstract


Manufacturing processes have a significant influence on the quality, productivity and competitiveness of polymer composite structures. This paper proposes to highlight the influence of manufacturing processes on the mechanical properties determined by compression test. Plates from reinforced fiber glass polymer composites obtained by hand lay-up and compression hand lay-up technology were studied. Also, the paper gives a mathematical model of the influence of structure on the compressive strength of bidirectional composites that use a regression analysis using a polynomial model. It is important to know the compressive strength and its dependence on the degree of reinforcement and the orientation angle of reinforcement material, because it gives information about the mechanical behavior of composite structure. Dependence of compression strength is determined by theoretical and experimental researches, using regression analysis of active experiment.

Key words: composite, fiber glass, hand lay-up, compression, polynomial model.
