Two of the major objections to a wider use of composites across industries are: the cost of Carbon Fiber and the difficulties of engineering composite structures. The affordability can be achieved by enabling the engineer to work with the right amount of material and optimal mix of composites (from chopped to continuous fibers) and corresponding (automated) manufacturing process. The predictability can be reached thanks to using multi-scale modelling technology to go down to the constituents for a more accurate assessment of the composite behavior until failure.

This seminar on 20 June will describe how virtual engineering, with a special focus on advanced material modelling, can help making composites more affordable and more predictable.
