Single part foam sealant helps produce a better gasket

It might not have the glamour of carbon fibre, but effective seals and gaskets play a vital role in product reliability and longevity. Yet, like mechanical fasteners, specifying them is often done with little thought. Gaskets and seals are not typically associated with innovation, with the default often being whatever was used last time.  Read More

Graphene: What does the future hold outside of the lab?

The 2010 Nobel Prize catapulted Graphene onto the world stage, and it's since captured the attention of the materials world. No doubt there are extraordinary opportunities.  Read More

Process brings colour to carbon

Carbon fibre has taken a leaf out of Henry Ford's book. You can have it in any colour you like, as long as it is black. By its very nature, carbon is black, and consequently as nice as any lacquered finish might look, if you want it in any other colour you have to resort to painting over the surface.  Read More

The materials innovation that make the XE saloon Jaguar's most important car yet

This, the aluminium intensive XE, is arguably the most important car that Jaguar has launched in its 92-year history. There have been more iconic, notably the E-Type, but it's fair to say Jaguar's future hinges on this new mid-size saloon poised to take on the might of German rivals like the BMW 3-series, Audi A4 and Mercedes-Benz C-class.  Read More

Composites set to benefit transportation industries

Introducing exotic materials into industries where metallic's have ruled is an ongoing challenge for the composites sector. The materials' inherent low-density has always been its best selling point.   Read More

Contamination concers: E-cigarettes

One of the most successful consumer products in recent years is also one of the unlikeliest. Electronic cigarettes provide an alternative for smokers based on inhalation of water vapour instead of toxic smoke. In 2012 alone, UK sales rose dramatically from £2.5million to £23.9million.  Read More

Changing consensus: Modern magnesium alloys

Everyone remembers holding a piece of magnesium foil over a Bunsen burner and watching it rapidly combust in to a brilliant white flame. It's a powerful demonstration that is etched on the mind, leaving many to automatically equate magnesium with flammability.  Read More

Should engineers be nervous when specifying recycled materials?

As raw materials get more expensive and scarce, why not take materials in the existing supply chain, all be it at the end of their life, and use those instead? It's a nice idea as it cuts down on the amount of material that has to be sent to landfill and can make the lifecycle of materials much more sustainable and economical.  Read More

3D printed organs a step closer

An unfortunate dichotomy is emerging from breakthroughs in 21st Century medicine. With better medical treatment people are living longer, but with an aging population comes an increase in failing organs. Coupled with unprecedented population growth, the shortage of donor organs is in a critical state.  Read More

Lightweight composite material could be a 'game changer'

An anonymous industrial estate on the outskirts of Basingstoke might not seem the place for the start of a revolution in lightweighting, but if the partnership between Composite Metal Technology (CMT) and C&J Antich & Sons lives up to expectations, then perhaps the town best known for its plethora of roundabouts will have another, more impressive, claim to fame.  Read More

Carbon fibre composites continue to proliferate throughout industry

Over the last decade, the civil aerospace industry has pioneered the manufacture of large composite components, taking the material from being considered exotic and destined for military and space bound applications, to the relative mainstream. And this has sparked interest from a number of different sectors including automotive and sporting equipment manufacturers looking to take out weight while improving strength.  Read More

Aerospace industry moves to carbon fibre wings

The superior strength to weight ratio of carbon fibre reinforced polymers has made the material a popular choice for aerospace applications, as engineers look to make more efficient – and therefore lighter – aircraft structures. But, while the material offers improvements in some key properties, others are not always desirable.  Read More

Physical testing optimises material properties

Many industries are currently re-evaluating the materials used in products, generally to improve upon cost, weight and performance. However, with this wave of change comes a need for thorough analysis. And while this has seen design engineers make intensive use of simulation software, the need for physical test data to correlate virtual predictions against has become another vital tool in the development process.  Read More

Polymers find use in engine transmissions

Boston and Toronto based BPG Werks has created an innovative mode of personal transport, dubbed the 'Shredder'. Resembling the love child of Robot Wars' Sir Killalot and a Segway PT. The all-terrain stand-on dual tracked vehicle (DTV) definitely has the cool factor. The DTV allows users to go from zero to a top speed of 25mph, even on steep uneven terrain or through water, in just a few seconds.   Read More

Polymers give longevity to components in the oil and gas industry

The word 'plastic' can sometimes be a vague term, with many perceiving it as an inferior, low grade material generally used for large volume production of simple everyday items from toys to carrier bags. However, when taking into consideration the extreme and arduous environment faced daily by the oil and gas industry, it is clear to see why engineering plastics are used across the industry on applications varying from the subsea sector through to LNG transportation and offshore.  Read More

Coating technologies help drive down cost in the aerospace industry

Commercial aviation in the early decades was expensive and exclusive. Today, however, we have come to expect frequent and relatively low cost air travel. But this market explosion has an environmental cost that continues to proliferate around the world.  Read More

Thermal history coating optimises combustion systems

The inherent inaccessibility and heat of combustion chambers make it an area that is not just difficult to analyse, it's sometimes impossible. But this goes for any hot environment from exhaust systems to turbochargers. Many conventional sensing methods can be ineffective. Though some expensive solutions exist, many engineers simply assume the worst and compensate for a lack of accurate data with over specified materials and over designed components.  Read More

Composites boost performance of track day car

Track day events have become increasingly popular in the last decade with many motorsport enthusiasts taking to the circuit to get a first hand taste of what it's like to travel around without a speed restriction. The trend has seen a number of mainstream manufacturers bring to market track-ready versions of production vehicles, to cater for individuals that want to drive cars optimised for the track.  Read More

Which type of composite material is right for you?

Make no mistake, composites are on the increase. The perception that the material is an exotic choice for engineers with big budgets is becoming more dated by the day. Composites are now filtering down from industries such as motorsport and aerospace, and finding more applications, in more industry sectors.  Read More

Digital simulation proves no match for physical testing

We live in a digital age. Everything is online and software driven, especially when it comes to design. The CAD companies are quick to tell you that physical prototyping is dead, and that 3D modelling and simulation is the way forward. However, while the phrase 'virtual prototyping' was coined some time ago, most in industry do not yet have the confidence to fully commit to it as a design philosophy.  Read More

What can be done with waste plastic at end of life?

Questions around what to do with waste plastic at end of its life should be given increasing emphasis at the design stage. Engineering Materials takes a closer look at the options available to engineers.   Read More
