Advanced Techniques for Delamination Toughening in Carbon Fibre Reinforced Composites
Abstract: Carbon fibre reinforced composites are widely used in various industries due to their excellent strengthto-weight ratio and stiffness properties. However, one of the major issues in these composites is delamination, which occurs due to the weak interlaminar bonding between the layers of fibers and matrix. Delamination leads to a reduction in the load-carrying capacity and structural integrity of the composite. To address this issue, several advanced techniques for delamination toughening …

Advanced Magnesium-Based Metallic GlassComposites for Biomedical Implant Applications: AMachine-Learning-Informed Approach
Abstract: Magnesium-based bulk metallic glasses (Mg-BMGs) combine strength, low density, and tunable degradability. Their amorphous matrix has a small plastic process zone. This zone is only about 4 μm wide. A small process zone keeps most glasses brittle. Adding a second phase is the best fix. This chapter extends Mg-BMGs to true composites. We call these Mg-based bulk metallic glass composites, or Mg- BMGCs. The chapter covers matrix engineering and interfacial …
