AB  - This  work investigates the   potential   and   the   applicability   of combining hierarchical and discontinuous microstructures to  overcome  the  brittleness  of man-made composites.  Finite  Element simulations were developed to model hierarchical “brick-and-mortar” composites, in which each brick of  the  structure  is  itself  made  of  an  arrangement  of  bricks  at  a  smaller  scale.  Then,  optimal brick geometrieswere identified, manufactured and tested. The experimental results confirmedthe potential of  such  microstructures  to  dissipate  energy  stably  through  damage  dispersion  in  the  whole  material, hence  delaying  damage  localisation,  and  providing  warning  before  failure.  Finally, non-self-similar microstructureswereidentified and optimised to improve furtherthe tensile response of composites. It was found that relaxing the  constraints  of self-similarity could delay damage  localisation even  more, and increase both the strength and the damage tolerance of hierarchical discontinuous composites.
