Analiza wytrzymałości doraźnej połączeń klejowych z fizycznie modyfikowanymi spoinami

The paper deals with analysis of a physical modification effect on adhesives and adhesive bonds on adhesive joints strength properties. Results of our studies show that a physical modification of adhesive bonds improves mechanical properties of adhesive joints. This includes an adhesive strength and a short-term strength, which is a result of adding glass fibers (as unidirectional fibers, fabrics and chopped fibers) and particulate matters (as micro and nano-particles). Numerical calculations are made for a two different models of the modified adhesive layer - an isotropic and orthotropic model. It seems that the orthotropic model is more appropriate to the short-term strength analysis of the adhesive bonds reinforced with glass fabrics. In such modeling of an adhesive layer, a distribution of stress is more probable.
