Automotive and transportation
In the automotive industry, modern bonding technologies allow for the optimal joining of diverse materials – high-strength steel, aluminium, magnesium and reinforced polymers – facilitating increasingly lighter, more energy efficient vehicles with reduced emissions. Adhesive bonding has led to the formation of new vehicle designs, increased durability and corrosion resistance, and even improved crash performance. As with any manufacturing process, these new lightweight automotive components must undergo rigorous examination to ensure durability and corrosive resistance in material bonds.
Today, over 15kg of adhesives are used in an average family car and this quantity is only set to grow significantly with emerging trends. The structural disruption of automotive components has accelerated the growth of the global automotive adhesive market.
In addition to lightweighting efforts, manufacturers will apply bonding technologies to maximise driver and passenger comfort and address noise, vibration and harshness (NVH) management. Adhesives will be used to bond acoustic insulating materials to the vehicle body structure, dampening out unwanted engine and road noise, plus their vibration absorbing properties also creates a smoother ride.
The future looks bright for technical adhesives with the continued expansion of the electric vehicle segment. The construction of automotive battery packs and heat-stressed structural joints presents real engineering challenges, and both thermal-resistant and electrically-conductive adhesives will be required right down the assembly line.
Furthermore, as heavy battery packs are loaded on to body structures this will intensify lightweight objectives in other vehicle components to fuel efficiency. Critical to the success of bonding technologies in modern electric vehicles will be the utilisation of automated, precision dispensing and fast-curing systems throughout the assembly line. Finally, alongside the merits of reduced carbon emissions, electric vehicles will need to be incorporated into a closed-loop economy, and bonding components are part of the conversation on how to develop efficient recycling solutions and reduce environmental impact.
The demand for electrically conductive adhesives and innovative bonding techniques, however, goes beyond car batteries and will be fuelled by the growing digitalisation of the automotive industry – and wider transportation segment. As transportation sensors, embedded systems and smart displays continue to grow in prevalence, silicone-based electrically conductive adhesives and optical bonding methods will be critical components in vehicle assembly.
Adhesives & Bonding Expo Europe will provide executives, engineers and purchasing and procurement professionals with the latest bonding solutions for automotive and transportation applications.
