The parametric relationship between the characteristics of production methods of bonded–riveted joints on the micro- and macroscales

The performance evaluation for rivet bonded joints in production and machine maintenance

“…The advantages of hot-melt adhesives applied together with rivet bonded joints are that they are easily removed and provide increased strength and stiffness to structures under static, dynamic and vibration loads [2,7]. The change of epoxy adhesives to less durable but more technological hot-melt ones provides the opportunity to solve the problem of joint serviceability.…”

“…In spite of hot-melt adhesive application simplicity their use causes a great number of technological problems. The most difficult problem is fast cooling of the hot-melt adhesive in its direct contact with a cold metal surface [7].…”

“…The sequence of dismantling operations for rivet bonded joints created with the use of hot-melt adhesives looks as follows: first, the bond line is cleaned, any dirt or paint, if there is any, is removed from the bond line. Then, rivets are drilled out (in a similar way to the process of rivet joint dismantling) [7]. After that the bond line is being heated with the hot air gun until the adhesive gets melted.…”

“…For comparative analysis of the joint performance two types of adhesive materials were chosen: thermoplastic hot melt adhesive and thermoreactive epoxy adhesive. Samples of these joints were prepared for shear tests [1,7] (fig.1).…”

“…2, fig. 3) is the absence of quantity evaluation of the design solution at each stage in contrast to the engineering solution where such evaluation takes place at each stage of calculations [7][8].…”
