IRDL Research Institute


To respond to current and future scientific and technological challenges related to materials, mechanical and systems engineering, the Brittany MATERIALS Engineering Laboratory (LIMATB EA 4250) common to UBS & UBO and the Brest Laboratory of Mechanics and Systems (LBMS EA 4325) common to ENSTA Bretagne, UBO & ENIB, from January 1, 2016, federate their research and training activities through research to form a large Institute Research for the engineer:


This grouping of two young dynamic Breton laboratories, close and complementary on a large number of scientific themes, will increase their visibility and promote the emergence of new research synergies.

IRDL’s ambition is to play, in the short term, an even more important role at regional, national and international levels in the resolution of current issues related to the engineering of materials and systems used in industrial sectors related to automotive, energy, aeronautics, health, transport and more particularly all areas in dynamic interaction with the marine environment, such as shipbuilding and offshore, marine energies.

The founding document of IRDL is an agreement binding the 4 supervising institutions: UBS, ENSTA Bretagne, UBO, ENIB and CNRS. It defines the governance of the IRDL, the arrangements for welcoming staff from one supervisory authority to another and for pooling resources dedicated to research.

The governance principles of the IRDL are those of the mixed research units (UMR) of the CNRS.

Strategic orientations

IRDL’s strategy is clear: to unite complementary forces in Engineering Sciences in the Brittany region to eventually become the benchmark laboratory for marine mechanical systems in France, and even in Europe.

As such, IRDL is therefore fully in the continuum « Fundamental research – Engineering – Technology ». Indeed, the new technological and scientific challenges are numerous, the main one being to produce cheaper while remaining resistant.

This positioning is unique in France.
