What are Composite Biomaterial Systems?


Made up of multiple parts/phases.


  • A naturally-derived material, such as human tissue (e.g. bone, cartilage, tendon, etc.).
  • A material developed for biomedical applications (e.g. implantable biomaterials for the reconstruction of bone).


Representative of our approach to research and development.

  1. Dec. 12, 2019New paper in Engineering Fracture Mechanics - Congrats to Daniel Dapaah!

    Congratulations to Mr. Daniel Dapaah (PhD candidate in the WCBSL) for his new paper published in Engineering Fracture Mechanics. The paper is entitled "Modelling the micro-damage process zone during cortical bone fracture" and you can find it here: https://doi.org/10.1016/j.engfracmech.2019.106811
