Two synthesized eco-epoxy components based on TA: (A) glycidyl ether and (B) phosphate ester, are used, as a replacement for the Bisphenol A (BPA) epoxy component, bonding aluminum (Al) carbon fiber reinforced polymer (CFRP). Their effect mode I fracture toughness (GI) is evaluated by Double Cantilever Beam (DCB) testing while using Digital Image Correlation (DIC) in-situ crack tip monitoring. ...

The present-day interest in the use of composite-steel joints primary marine structures requires an in-depth knowledge fatigue performance thick adhesive joints. This paper reports on experimental tests performed compliant (i.e., and ductile) based a two-component methyl-methacrylate unaged aged conditions. Bi-material double strap joint with bondlines is subjected to quasi-static loading, duri...

Abstract As adhesively bonded layered devices scale down, micro-scale adhesive layers become common and play a key role in the overall performance of micro devices. Herein, we use strain gradient elasticity to characterize propose an analytical size-dependent model predict mechanical behaviors structures. The results indicate that local interfacial tractions global adherend displacement both sh...

Adhesion is the procedure of forming an adhesive joint. The initial substrate is termed adherend and the material producing the interface is termed the adhesive [1]. The functions of dental adhesives is to promote conservation of tooth structure and enable minimally invasive dentistry, reinforcement of weakened dentin or enamel, reduce marginal staining, reduce microleakag and may also reduce p...

Abstract Natural fibre-reinforced composites have attracted a great deal of attention by the automotive industry mainly due to their sustainable characteristics and low cost. The use is expected continuously increase in this area as cost weight vehicles could be partially reduced replacing glass fibre aluminium with natural composites. Adhesive bonding preferred joining method for increasingly ...

In adhesive bonding, two different substrate materials are joined together, usually by forming chemical bonds. The can stick things together. loading rate and deformation mode easily change the mechanical properties of material. Hence, a vital aim current study is to evaluate strain effect on damage response joints for Mode I scenarios. adherend material was aluminum AL6061-T6, Araldite 2015 ad...

On-demand adhere to and detach from soft wet surfaces are crucial for hydrogels applications in tissue engineering, machines, robotics. Whereas strong adhesion has been achieved between hydrogels, on-demand switching weak benign detachment is still under explorations. Herein, we report an approach switchable by invoking a mechanical process, wrinkling. The demonstrated bonding two hydrogel adhe...
