Project mission

The main objective of JOIN3D is to promote the safe and effective use of Double-Double laminates, capitalizing on their more efficient design and potential for lightweight construction. We aim to contribute to the understanding of the energy absorption capabilities of double-double composite joints with respect to standard construction and to further develop analytical and numerical prediction tools to assist in their design.

Research Questions

Question 1

When compared to standard composite laminates, do double-double laminates present superior energy absorption capabilities, that could thus contribute to weight reduction in the presence of bolted joints?

Question 2

How does the 3D composite joint failure envelope of standard and double-double laminates compare?

Question 3

Can high-fidelity models accurately predict the failure load, energy absorption and overall failure mode

Question 4

Can composite joints be designed based on a macro-scale simplified joint model and if so, how effective are these models compared to direct detailed numerical simulation/experiments?
