Paragraph starter
The processing of carbon-fiber-reinforced bulk metallic glass composites, as demonstrated by Kim et al. (2001), highlights the critical role of reactive wetting. The formation of a ZrC layer at the fiber-matrix interface facilitated a homogeneous distribution of fibers, achieving a significant volume fraction of approximately 50%. This suggests that controlling interfacial chemistry during manufacturing is a viable strategy for enhancing the uniformity and performance of composite materials.
