Fibre-dominated Strength of Multidirectional Laminates Workshop

After five successful workshops on defining strength and measuring tensile, compression, shear and transverse strength, we are now organising our 6th workshop on Tuesday 28th March 2023 at 2pm. This online workshop focuses on how the fibre-dominated strength of a multidirectional laminate relates to the strength of a UD composite.

  • Topic How the fibre-dominated strength of a multidirectional laminate relates to the strength of a UD composite
  • Date Tuesday 28th March 2023
  • Time 2pm
  • Location Zoom
  • Fee & audience Free and open to all

6th Online Workshop

The workshop will be an opportunity for everyone to comment on which aspects you agree or disagree on, on best practices, and what alternative ideas you might like to put forward. We have now also drafted a short paper to outline the key issues and as a starting point for discussions. 

Agenda

The event will be held on Zoom. We have allowed three hours so we are not constrained by time, but may not use all of this, depending on the number of participants.
Note: the agenda is in UK time, so do not forget to convert into your own timezone. The UK/EU will be switching to summertime right before our workshop, so please factor this in if you are in a time zone that does not switch or that switches later.
