In a new paper published in ‘Materials & Design’, an engineering team from the University of Glasgow engineers have developed a new metamaterial, which is capable of higher impact resistance than its counterparts. But despite being lightweight, how is it able to integrate safety during car crashes?
Crux of the Matter
What Is The Material?
3-D-printed material, which is made by combining commonly-used plastics with carbon nanotubes. This makes it tougher and lighter than similar forms of aluminium.
So This Is A Metamaterial?
Yes. Metamaterials are artificially-created, to manifest properties which do not occur in the natural world. Eg: plate-lattices
How Are Plate-lattices Light?
They are cubic structures made from intersecting layers of plates, which have high stiffness and strength, despite having space between them. These spaces called porosity, make the plate-lattices lightweight.
Impact Resistance Offered?
Those designs were then subjected to a series of impact tests. Eg: Dropping a 16.7kg mass from a range of heights to determine their ability to withstand physical shocks.
What Were The Results?
Using specific energy absorption that determines a material’s ability to absorb energy relative to its mass, the polypropylene hybrid plate-lattice was found to withstand 19.9 joules per gram.
Would The Plastic Used Be Recyclable?
Yes, as per Dr. Shanmugam Kumar, Reader in Composites and Additive Manufacturing. “In a net-zero world, circular economic models will be central to making the planet more sustainable.”
Intersection of M&M
This output of Mechanics and materials can help develop safer, lighter and more durable structures for use in the automotive, aerospace, renewables and marine industries.
- The Hall–Héroult process is the major industrial process for smelting aluminium. Aluminium became much more available to the public with the Hall–Héroult process developed in 1886, and the mass production of aluminium led to its extensive use in industry and everyday life.
- The year 1886 is regarded as the birth year of the modern car when German inventor Karl Benz patented his Benz Patent-Motorwagen. One of the first cars accessible to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company.
