Dr Zhutao ShaoThe problem

When a manufacturer, for example  a car maker, wants a new component made, it will go to a supplier with its specifications. To make this new item, the supplier needs material multi-axial property data to predict its materials’ response in the manufacturing process. Existing testing methods cannot supply such data across all possible temperature and stress states.

Solution 

To solve this issue, Dr Zhutao Shao and his colleagues from Imperial College London have developed and patented the world’s first high-temperature multi-axial material testing system. This patented testing process involves stretching a piece of material from multiple directions and under different service conditions until it fractures. Customers are then given the data and can use it to optimise their material’s structure.

Most existing systems use room temperature for testing and some may go up to 300° to 500°C. Dr Shao’s innovation can go over 1,000°C when needed. This option is important when judging how a material will behave under various stress states during the hot stamping manufacturing process. His multi-axial testing also undertakes fatigue, tension and compression testing of materials within a wide range of temperatures. The suite of checks are labelled ‘hot multi-axial tests’.

Multi-X Solutions already collaborates with car component suppliers for lightweight structural design and production of vehicles and will start trial sales in 2020. The company currently has one service and two products open to the transportation industry. Multi-X Solutions also has a materials database that will be added to as the company conducts tests on more engineering materials and structures.

The market that Multi-X are working in stands at £850 million worldwide and is rapidly expanding. The company is now looking to further develop and standardise the cost-effective testing methods for the data-driven advanced manufacturing industry.
