Principles of Increasing the Winding Effectivity of Composite Prepregs to Construction Application

Popis výsledku v původním jazyce

The development of composite materials for weight reducing is a trend in transport and other industrial areas. The composition of the composite material generates a synergistic effect that provides their advantages. The composite consists of a dispersive and continuous phase. For composites, different fibers (carbon, glass, basalt, textile and natural fibers) and plastic matrices with specific properties can be applied. The type, quantity and arrangement of fibers in the composite are designed for strength characteristics depending on the maximum applied load. Samples of the composite material were made by fiber winding technology on non-bearing core with required geometry. An image analysis of the structure and morphology was performed by scanning electron microscopy (SEM). The study of matrix penetration among fibers has shown that the directional fiber winding production technology in the case of uncontrolled winding significantly affects the resulting ratio between fiber and matrix area. This was reflected in the standard tensile, bending and impact tests by a reduction of mechanical properties of the resulting composite. Insufficiently, saturated areas create the source of defects and crack propagation in the composite. Mechanical properties were determined from numerical models. The nature of strain and stress distribution in individual layers have been identified. The results of the mechanical tests were compared with the numerical model. A comparison of experimental results and numerical models shows that fully controlled winding allows increasing mechanical characteristics of the resulting composite. The cause can be found in the optimal distribution of the fibers in the composite.
