Andic oxidation of high-modulus carbon fibers in sulfuric acid under different electric fields

Cailiao gongcheng
The inert surface of high-modulus carbon fiber leads to the weak interface between it and the resin matrix， which limits the performance of high-modulus carbon fiber composite in many application scenarios.

Preparation of Carbon Fiber/Carbon Composites Using Intercalated Carbon Fibers

TANSO, 1992
Carbon fiber/carbon composites were prepared from carbon fibers intercalated with AlCl3 as reinforcements, and coal tar pitch or phenol resin as matrix precursor. A1C13, which is known to have a catalytic effect on the carbonization process, was de-intercalated from carbon fibers during the preparation of composites, i.e.

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

Advanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Enhancement of the Through‐Thickness Electrical Conductivity of Carbon‐Fiber‐Reinforced Plastics Using Large Graphite Particles

Advanced Engineering Materials, EarlyView.
To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.
