Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Dynamic creep behavior of acrylic bone cement [PDF]

Journal of Biomedical Materials Research, 1995
AbstractRecent studies concerning the fixation of cemented total hip arthroplasty (THA) have led to new hypotheses about the dynamic, long‐term failure mechanisms leading to prosthetic loosening. As a result, the long‐term mechanical behavior of acrylic bone cement has gained more interest since little is known about these properties.

Injectable Bone Cements: A Generational Framework for Bioactivity, Porosity, and Mechanobiological Design at the Nanoscale

Advanced NanoBiomed Research, EarlyView.
Key demographic, biological, and material considerations that drive the need for advanced injectable bone cement technologies. Injectable bone cements (IBCs) are widely used in orthopaedic and craniofacial applications due to their minimally invasive delivery and ability to provide early mechanical stabilisation.
