Abstract

Carbon fiber reinforced ZrC–ZrB₂ based (C/C–ZrC–ZrB₂) composites, which were prepared by reactive infiltration of zirconium into a porous C/C–B₄C preform, had the density of 3.07 g/cm³, the open porosity of 9.1% and the flexural strength of 147 MPa. ZrB₂ matrix was surrounded by or adjoined to the ZrC one and Zr–ZrC eutectic including residual α-Zr dispersed among the reaction-formed ceramics. The amount of ZrC–ZrB₂ matrix in the composites was ∼30.2 vol.%. The mass loss rate and the linear recession rate under an oxyacetylene torch were 0.0039 g/s and 0.01 mm/s, respectively.

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
