Carbon Nanotube Arrays with Strong Shear Binding-On and Easy Normal Lifting-Off

This study presents a simple technique for positioning helical carbon nanotubes (CNTs) into chemically-etched vertical micro-channels on an aluminum (Al) substrate for strong adhesive bonding with carbon fiber composites. Helical CNTs with diameter up to 100 nm and length up to 10 μm were dispersed evenly in an acetone-diluted resin pre-coating (RPC) solution consisting of 90 wt% acetone + 10 wt% resin (without hardener), then applied onto the chemically etched Al substrate with vertical micro-channels. CNTs were dragged into those vertical micro-cavities through the capillary action during the evaporation process of acetone. The shear bond strength was more than doubled by the quasi-Z-directional CNTs, confirming the critical role of CNT bridging across the interface between the epoxy adhesive and Al substrate. Scanned electron microscope (SEM) and focused ion beam (FIB) were used to reveal micro-channels on the Al substrate. RPC on the surface of carbon fiber composites is also beneficial.

Enhanced resistance-welding hybrid joints of titanium alloy/thermoplastic composites using a carbon-nanotube lamina

Multi-walled carbon nanotubes (MWCNTs) in the form of "forests" were synthesized directly on the surface of stainless steel (SS) mesh from ethanol flame volume. The growth dependence of the MWCNT forests on the porosity of SS mesh substrate and the morphologies and growth mechanism of the MWCNT forests were investigated in detail by a combination of turbulent flow simulation, scanning electron microscopy (SEM), transmission electron microscope (TEM), and Raman and X-ray diffraction (XRD) spectroscopy. The growth height of the MWCNT forests exhibited a strong dependence on the flame gas flow rate controlled by the porosity of SS mesh substrate, and the maximum averaged height of the MWCNT forests reached 34 μm. Most MWCNTs grew perpendicularly on the surface of SS wires, and some branch, welded, and spiral structures were observed by SEM and TEM. The MWCNT-decorated mesh was used as a novel heating element to weld glass-fabric-reinforced polyetherimide (GF/PEI) thermoplastics. We found that the maximum tensile lap-shear strength (LSS) of the welded joints could reach 39.21 MPa, an increase of 41% in comparison with that of conventional SS mesh-based joints.

Improved mechanical properties of resistance welded joints of thermoplastic composites by versatile graphene oxide

The joining of composite parts with weight reduction and cost saving is being developed to improve aircraft performance. The high-efficiency resistance welding technology was hence explored for joining glass fabric reinforced polyetherimide (GF/PEI) laminates in this work and a composite PEI films reinforced with carbon fiber felt (CFF) reinforced laminae was embedded into the interface of the welding region to enhanced the strength of the joints of GF/PEI. The effects of CFF incorporation on the welding speed and the lap shear strength (LSS) of welded joints were investigated in comparison with those of the CFF-uncontained welded joints. The CFF-incorporated resistance welding speed was accelerated and its LSS was enhanced evidently, the maximum LSS value reached 32 MPa. The fracture mode and mechanism of welding implants, which varied with t w from the linear tearing to the annular tearing due to the coupling effect of the improvement of PEI molten state and the occurrence of PEI thermal degradation, were illuminated according to the test results from ultrasonic C-scan and SEM.
