Emerging technologies this year

The emerging technologies positively disrupt the existing order, are attractive to investors and researchers, and expect to achieve considerable scale within the coming five years. These are the top 10 emerging technologies for 2019: Bioplastics for a circular economy Less than 15% of the world’s plastic is recycled, with the rest incinerated, abandoned or sent to landfill. Biodegradable plastic offers a solution but lacks the strength of conventional materials. A breakthrough idea promotes the circular economy by using cellulose or lignin from plant waste, which increases material strength without using crops that could otherwise be used for food. Social robots Today’s robots can recognise voices, faces and emotions, interpret speech patterns and gestures, and even make eye contact. Droid friends and assistants are becoming part of everyday life and are being used increasingly to care of the elderly, educate children and undertake all sorts of tasks in between. Metalenses Making the lenses used by mobile phones, computers and other electronic devices smaller has been beyond the capabilities of traditional glass cutting and glass curving techniques. But advances in physics have led to miniaturised, lighter alternatives to established lenses, called metalenses. These tiny, thin, flat lenses could replace existing bulky glass lenses and allow further miniaturisation in sensors and medical imaging devices. Disordered proteins as drug targets “Intrinsically disordered proteins” are proteins that can cause cancer and other diseases. Unlike conventional proteins, they lack a rigid structure so change shape, making them difficult to treat. Now scientists have found a way to prevent their shape-shifting long enough for treatment to take effect, offering new possibilities for patients. Smarter fertilisers Recent improvements in fertilisers have focused on their ability to slowly release nutrients when needed. However, they still contain ammonia, urea and potash which damage the environment. New fertilisers use more ecologically friendly sources […]

Is 5G ready for manufacturing?

High profile scandals aren’t typically good for the technology sector. Whether it’s diesel emissions, large data breaches or cyber-attacks on mission-critical infrastructure, scandal has the power to cripple a technology even before it’s gotten off the ground. Despite what recent headlines may have you thinking, 5G has the potential to be a hugely positive force in the world of manufacturing, heralding in a new era of technological innovation. While 3G and 4G offered incremental improvements in speed and bandwidth, 5G will be the first cellular, wireless platform to truly offer reliable integration with machine-to-machine and industrial IoT systems. It will do this in three ways. The first is enhanced mobile broadband (eMBB); 5G offers peak data rates of 10 Gbps and can handle 10,000 times more traffic than its predecessors. Secondly, it offers Ultra Reliable Low Latency Communications (URLLC). This means it has a radio latency of less than 1 ms and an availability of over 99.9 per cent, making it ideal for industrial use where uptime is critical. Thirdly, it offers Massive Machine-type Communication (eMTC), allowing it to handle a density of one million devices per square kilometre. It can also deliver ultra low-cost machine-to-machine communications and can last up to 10 years on battery, great for battery operated low power devices. So, what does this mean for industry? Well, not only will 5G open the door for real-time wireless sensor networks and location and asset tracking, it will also enable plant managers in smart factories to rely on seamless communication with a fleet of autonomous guided vehicles (AGVs) without worrying about network dropouts. What’s more, manufacturers that may have been sceptical of adopting the likes of augmented and virtual reality technologies will be able to take full advantage of them for real-time simulation and predictive maintenance. In industrial […]

How viable is additive manufacturing?

~ The manufacturing and legal issues surrounding additive manufacturing ~ In 1984, Charles Hull invented the first 3D printer, which used stereolithography to build up a plastic product layer by layer. Over 35 years later, additive manufacturing (AM) is drastically altering a range of industries, from manufacturing to the medical sector. But what are the limitations of the technology? In some applications, component manufacturing is shifting away from traditional subtractive machining methods and towards additive manufacturing techniques. The broadening of the applications of AM is causing manufacturers to assess the viability of using it in their own facilities. To do this, there are a few considerations to make before turning to 3D technology. Quality not quantity When moving from one manufacturing method to another, quality is a huge factor, particularly in highly regulated industries like aerospace and medical devices. In fact, quality has been one of the major hurdles to the widespread adoption of AM. One critical consideration is that quality and consistency must be the same machine to machine, regardless of location. Powder bed fusion is one of the most frequently used additive manufacturing methods and there is a possibility that it may introduce defects. However, if the process has a constant thermal gradient, it can prevent warping of the product, avoiding the introduction of defects due to incorrect temperatures. Another concern is that unsintered powder will degrade as a result of heat exposure and that this could impact quality, although regular changing of the powder can prevent this from becoming an issue. When investing in an AM system, manufacturers can overcome quality concerns by working with an experienced partner, who provides training and support on best practice. Those looking to invest in AM parts produced elsewhere should be […]

Collaboration results in interleaving veils for composite toughening

New Zealand company, Revolution Fibres, has collaborated with Mitsubishi Gas Chemical Company, Inc. to develop a next-generation nanofiber interleaving veil for improving the toughness of carbon fibre composites. The new nanofibre veil material, called Xantu.Layr XLB, has particularly strong application possibilities in the aerospace sector. Xantu.Layr XLB is made from Mitsubishi’s recently developed XD10 thermoplastic, bio-based polyamide resin, LEXTER. LEXTER is a xylylenediamine-derived polyamide resin that has been demonstrated successfully as a thermoplastic matrix for composite materials. It is tough, strong, and chemically resistant, and has the added benefits of being hydrophobic and highly compatible with epoxy resin when in the form of a nanofiber veil. These properties enable Xantu.Layr XLB nanofibre interleaving veils to improve the performance of thermoset composite laminates without being compromised by exposure to high humidity, gasoline or a range of other chemicals. Another benefit of this new nanofibre veil is the lower cost of manufacture, resulting in a lower sale price. Dr. Nobuhiko Matsumoto, a Research Manager at Mitsubishi Gas Chemical, said that they “were thrilled to see LEXTER in the form of a nanofiber veil and could see many commercial possibilities for applications.” Xantu.Layr is produced using a proprietary production method (Sonic Electrospinning Technology), and is an ultra-thin non-woven web consisting of kilometre long thermoplastic nanofibres, with each one around 500 times thinner than a human hair. When placed in-between the plies of carbon fibre in a composite laminate, Xantu.Layr significantly improves the fracture toughness (delamination resistance), compression after impact strength (damage tolerance) and fatigue resistance of the composite without adding any significant thickness and weight. Xantu.Layr nanofibre veils can improve composite materials by providing nano-scale reinforcement of the brittle matrix resin, resulting in a tougher resin (even when used with already toughened resin systems) which is less prone to micro-cracking when stressed or […]
