Irregular Winding of Pre-preg Fibres Aimed at the Local Improvement of Flexural Properties

Popis výsledku v původním jazyce

The main undisputed benefi t of using long fi bre composite materials, whose properties could be targeted for a particular application, lies in the effi cient utilisation of material. Using a method of pre-impregnated fibre winding, a rod with a reinforced middle part was created through the local adjustment of the winding angle in order to increase the local bending stiff ness. The aim of our work was to describe, experimentally and subsequently using appropriate numerical models, the behaviour of two composite rods, one with a locally variable winding angle and the other with a constant winding angle. The diff erence in the mechanical behaviour of both structures was clearly evident during the experiment. By using a suitable composite pre-processor and by choosing some multiple element sets, it was also possible to accurately simulate the real behaviour of such components, which actually have several regions, each with diff erent mechanical parameters. Together with the expected diff erent fl exural strength, a traditional three-point bending test also explored the diff erent shape of the resulting deformation in the two compared parts. Diff erences in the maximum strength and the mode of fi nal deformations were also identified.
