Adhesive bonding technology present a perspective method of various materials bonding and replacing conventional bonding eg welding. A geometric shape modification of bonding material and an adhesive reinforcing by glass fibres to increase tensile strength of adhesive bond was subject of this research. The bonding material was modified into preformed angles 5, 10, 15, 20 and adhesive bond with 0 was set as the etalon. The adhesive was modified by glass fibre with weight 80, 110 and 160 gm-2. The research proved tensile strength increase from 4 to 48% by various preformed adherent angles. The research also proved tensile strength increase from 4, 8 to 93, 7% by adhesive reinforcing with glass fibres with various weight. Statistical analyse proved significant difference between measured values on significance level 0.05 (p< 0.05) ie influence of adhesive bond modification on mechanical properties was proved.
