The paper presents research on the durability of adhesive composites, which may be used
for the repair of technical objects. Durability of adhesive composites is understood in this paper
as a material ability to transfer long lasting loads. Since that kind of information is not provided
by manufacturers, the long-term strength and fatigue-life of selected adhesive composites are
determined; especially with regard to their use in expedient (temporary) repairs of weapon
systems. The results obtained show that safe values of the maximum long-term and fatigue
loads of the adhesive composites investigated should be a half of the short-term strength
obtained in a static tests.
Keywords: durability of materials, adhesive composites features, long-term strength, fatigue life
