Laser surface treatment to enhance the adhesive bonding between steel and CFRP: Effect of laser spot overlapping and pulse fluence

Xin Zou et al.

Summary: Adhesive bonding between steel and carbon fiber reinforced plastics (CFRP) is improved by laser surface treatment. Surface roughness, energy, and chemical composition of steel are studied after different laser treatments. Results show that surface properties are closely related to the interfacial bonding strength between steel and adhesives.

Strengthening the bonding interfaces of hybrid titanium carbon laminates by bionic micro texture and carbon nanotube pinning

Shujian Li et al.

Summary: A reliable strategy is proposed to enhance the bonding ability in hybrid titanium carbon laminates (HTCLs), based on the pinning effect produced by bionic micro texture etched by laser on titanium and the introduction of multiwalled carbon nanotubes (MWCNTs) into the adhesive layer. The micro texture groove width, laser scanning times, and MWCNTs content are varied in the samples, and their morphologies, wettability, and bonding properties are studied. Results show that both the micro texture and MWCNTs can improve interfacial bonding properties, with the optimal TSS and ILSS achieved at a groove width of 30 μm, 30 laser scanning times, and 0.4 wt% MWCNTs content.

A simple and effective resin pre-coating treatment on grinded, acid pickled and anodised substrates for stronger adhesive bonding between Ti-6Al-4V titanium alloy and CFRP

Yunsen Hu et al.

Summary: This study investigated the performance of different surface treatments for adhesive bonding between carbon fibre reinforced polymer (CFRP) and titanium alloy. Acid pickling, grinding, anodising treatments, and resin pre-coating (RPC) were employed. The results showed that grinding and anodised specimens had higher bond strengths than acid pickled specimens. RPC treatment significantly increased bond strengths, especially on rough surfaces. The combination of NaOH anodising and RPC treatment yielded the highest bond strength and changed the failure mode.

Experimental study of CFRP laser surface modification and bonding characteristics of CFRP/Al6061 heterogeneous joints

L. Y. Xu et al.

Summary: This paper studied the effect of laser modification on the bonding strength of CFRP surfaces. Different laser treatment patterns were used to improve bonding strength. The highest bond strength was achieved with an annular pattern. The exposed continuity of carbon fibers and residual resin directly affected the bond strength. Additionally, the bond strength initially increased and then decreased with increasing scanning times, with the capillary effect of carbon fibers and air pressure in micro grooves playing a leading role.

Enhancing the adhesive bonding strength of Ti6Al4V sheets with fiber laser texturing

Fatih Hayati Cakir

Summary: In this study, it was found that laser texturing significantly improves surface wettability of titanium alloy sheet blocks, thereby enhancing bonding performance. Using a two component epoxy adhesive binder, lap joint bonding was conducted after surface preparation. The results showed increased adhesive strength and shear lap joint bond strength compared to samples without laser texturing.

Laser-based pretreatment of composite T-joints for improved pull-off strength and toughness

M. Hashem et al.

Summary: This study demonstrates the effectiveness of two CO2 surface laser treatment strategies in improving the strength and toughness of adhesive bonding in T-joints. The first strategy involves uniform laser treatment, while the second strategy involves laser patterning. The laser-treated joints showed progressive failure modes and exhibited improved strength and toughness compared to traditional surface-treated joints. The laser-patterning strategy further enhanced the strength and toughness of the joints, due to the crack arresting at the transition between treatments and the formation of adhesive ligaments.

Evaluation of Surface Treatment for Enhancing Adhesion at the Metal-Composite Interface in Fibre Metal-Laminates

Magda Drozdziel-Jurkiewicz et al.

Summary: This paper investigates the effects of metal surface treatment on adhesion in fibre metal laminates (FML), analyzing different treatments on aluminium and titanium surfaces. The study finds that chromic acid anodizing is the most effective method for enhancing adhesion, while P2 etching of aluminium is also a suitable technique. Additionally, the application of sol-gel coating increases the surface free energy and may improve adhesion.

Hui Wang et al.

Summary: A novel ultrasonic vibration-assisted adhesive bonding process was proposed for carbon fiber-reinforced polymers (CFRPs), significantly improving the shear strength of the bonded joints by 340%. The ultrasonic action contributed to a more compact interface, enhanced mechanical anchoring, and increased bonding area on laser-treated surfaces.
