A REVIEW ON EXPERIMENTAL INVESTIGATION OF WELDED BUTT JOINT REPLACED WITH RESIN WELD

Mechanical engineering

The main parameters that affect the performance of resin joints such as surface treatment, joint configuration, geometric and material parameters, failure mode etc. are discussed. The environmental factors such as pre-bond moisture, moisture and temperature are also discussed in detail and how they affect the durability of adhesive joints. Lots of shortcomings were resolved during the last years by developing new materials, new methods and models. However, there is still a potential to evaluate and identify the best possible combination of parameters which would give the best performance of composite bonded joints. The selection of the manufacturing bonding method usually depends on the substrate to be bonded, service condition, area of application, etc. However, there is a lack of understanding of bonding methods on the failure behaviour and the relationship between bulk adhesive strength and joint strength. Suitable manufacturing bonded joint method for a particular area of application is important, especially in case of the composite repair method, as the parent material (damaged) already contain moisture and suffered other changes during the service period.
