The topic of the online workshop was "Measuring UD tensile strength and the factors affecting it".

Professor Michael Wisnom presented a paper on the topic, followed by seven short presentations.

Over 100 people from 20 countries attended the workshop and participated in an interesting discussion after the presentations.

A recording of the workshop can be watched on the Bristol Composite Institute's YouTube channel. The PowerPoint presentations and a paper summarising the topic are available for download via the links below.
