Obiettivo del progetto (Objective)
There is a high demand for the design of lightweight energy efficient structures for transport applications in order to meet CO2 emissions targets set worldwide. To achieve this designers have introduced the concept of “hybrid” structures where two or more lightweight materials are used each possessing unique properties that when joined together result in high performance lightweight structures that would not have been possible if a single material was used. This approach requires the development of joining techniques for materials with fundamentally different physical properties that will ensure the safe and reliable transfer of load between the constituent materials. SAFEJOINT addresses this challenge by developing novel techniques for metal to metal and metal to composite joining as well as developing novel techniques for the non-destructive inspection and evaluation of such joints in order to enhance confidence to designers and end-users of hybrid structures of their through life safe performance.
Introduzione (Teaser)
Composite or hybrid materials in which two or more individual materials are joined together can produce high-performance lightweight structures not possible with either material alone. Scientists are exploiting carbon nanotubes at the joint to enhance bond characteristics.
Descrizione progetto (Article)
EU-funded scientists launched the http://safejoint.net/ (SAFEJOINT) (Enhancing structural efficiency through novel dissimilar material joining techniques) project to improve joint formation and develop non-destructive inspection (NDI) and evaluation technology. The focus is on forming hybrids of polymers and metals as well as on joining dissimilar metals, both exploiting the unique properties of multi-walled carbon nanotubes (MWCNTs) at the joint. The MWCNTs are expected to improve the mechanical properties of the joint.
The team has explored a variety of different ways to introduce the MWCNTs into the bond line of the joint between the metal and polymer composite, some of which are highlighted here. Electrophoretic deposition (EPD) takes advantage of the electrical conductivity of MWCNTs. Scientists experimented with EPD of MWCNTs on both the fibre reinforcement and on the metal substrate, achieving better results on the fibre component.
Dispersion of MWCNTs in adhesive resins is particularly promising, demonstrating a sort of catalytic effect with some resins such that curing time was significantly reduced or even unnecessary. The optimal MWCNT-resin compositions have been determined for each resin. Mechanically interlocking titanium-composite joints were fabricated by scientists and demonstrated to have excellent mechanical bond strength. The mechanisms are currently being investigated with finite element analysis.
Friction stir welding is a solid-state technique for joining dissimilar metals. It relies on the heat of friction created by a tool against one of the metals rather than an external heat source. The second metal is joined to it using mechanical pressure. Experiments have been conducted and a model has led to equipment design and manufacture. MWCNTs have been introduced into the bond using chemical vapour deposition.
Finally, NDI technology is under development and has been tested successfully on both metal-metal and metal-composite joints with artificial defects. Current work is geared towards optimisation of signal processing for enhanced resolution of defect detection.
SAFEJOINT is developing advanced bonding technologies for dissimilar materials relying on MWCNTs. Enhanced usage of novel lightweight components for the transport sector will significantly reduce weight, fuel consumption and associated emissions. This will benefit both industry and the environment.
