Abstract
Carbon fibre products are getting to be common today for its high strength and lightweight, thus it is desirable to feasible its quality within the race car design as much as possible. This paper focuses on usage of carbon fibre tubes (20x2) for suspension links connecting an upright with chassis of a race car. The end of each link is bonded to an aluminum holder housing a spherical bearing. Thus there risen a question about quality and durability of such joint. Hence number of tests (tensile, compressive, torsion) were performed using various glues (Scotch-Weld 490 3M and Tech-Lit 2KE) and surface finishes of glued surface to see the influence of each individual aspect. The most important was tensile test and best result reached combination of Scotch-Weld 490 3M and smooth glued surface. Best result of tensile test with Tech-Lit 2KE reached combination with knurled glued surface. Other tests, compresive and torsion, were additional to this research.
