“…In terms of difficulty making the adhesive bond can be based on the results of several studies concluded that bonding thermoplastics is compared with thermoset bonding much more complicated [Neto 2012]. In practice, thermoplastics are joined exclusively by reactive adhesives [Argoud 2018]. In addition, when bonding two thermoplastics, solvent-free adhesives are exclusively applied [Arash 2014].…”

Nowadays, due to the requirement to achieve specific product properties or to reduce the weight of machine parts, conventional metal materials are replaced by plastics. Various methods are used to connect them to assemblies. The task of the joint is to provide a perfect, but particularly reliable, compact unit. One of the relatively effective methods of bonding plastic parts is their bonding. In addition to the properties of the adhesive used, the quality and reliability of the bonded plastic components also depend on the properties of the plastic materials used. The aim of the experimental research was therefore to contribute to the knowledge in the field of strength properties of bonded joints using PA6 and PBT plastic materials with different amount (wt%) of recycled polymer.KEYWORDS bonded joints, recycled plastic, polyamide 6 (PA6), polybutylene terephthalate (PBT), shear strength, testing.[STN EN 28510-1] Adhesives.

“…[16][17][18] They show a great potential in daily life and several industries, such as automotive, transportation and aerospace. [19][20][21][22][23] Glass fiber (GF) is one of the most commonly used reinforcements in the composites due to its low cost and relatively good mechanical properties. 24,25 Nevertheless, thermoplastic composites have few drawbacks, for instance, poor impact resistance 26 and weak ductility properties by comparison with metal alloys.…”

This article presents a research into the development of novel Hybrid Laminates (HLs) prepared with the use of hot-pressing method. Two types of HLs are fabricated through the composite coating with different fiber amounts (40 and 50% wt.) of only one surface of 7075-O Al alloy substrate. Effects of the fiber contents of the thermoplastic composite in the hybrid structures are investigated with regards to the tensile and flexural properties. The influence of bending load applied from different surfaces on flexural responses is also evaluated. The tensile test results indicate that the increased fiber ratio slightly affects the failure load of composite layer in the HLs. On the other hand, the flexural strength decreases with the increasing fiber amount in the HLs whether the three-point bending is performed on the Al surface or the composite layer. Scanning electron microscopy (SEM) is used to study the fracture surfaces after the mechanical characterization. From the SEM observations, it has been realized that fiber/matrix debonding is the key failure mechanism during the tensile tests. The failure mode of both HLs is delamination in the PP composite at the tensile side when the bending applied from the Al layer.
