Özet: In this study, after bonding polymer matrix composite joints via different methods, the effect of the methods to tensile force were investigated. Firstly, tensile test specimens of plain weaved carbon fiber fabric reinforced epoxy composite were manufactured. Hot pressing after hand layup method were utilized in production. Specimens were sized in accordance with the ASTM D412 standard. Each sample were cut into half and bonded with different methods. Bonding methods include fastening with bolts, bonding with a low-cost two-component adhesive, widely available in the market, bonding with lamination resin from which the composite material is produced by, and bonding with the same lamination resin with carbon fiber powder. Bonded specimens were subjected to tensile test according to compare joint forces. While the breaking force of the region joined by the bolts gives the least value, the tensile strength of the regions bonded with the low-cost two-component adhesive that can be found in the market has the highest value and these values are 2278,67 N and 12062 N, respectively.
