In Situ Crystallization‐Induced Coherent Interfaces for Simultaneous Toughening and Hardening of Reinforced Silicon Carbide Nanoceramic

National Materials, EarlyView.
This work reports the fast hot‐pressing sintering of precursor‐derived amorphous SiC raw powders to prepare HfC‐reinforced SiC nanoceramic with coherent HfC/SiC interfaces. Through the synergistic effects of nanocrystallization strengthening and interface engineering, the simultaneous enhancement of three typically competing mechanical properties, that

Effect of Temperature on Tensile Properties of Electrospun Nanofibre Interleaved Carbon Composites

Polymer Composites, EarlyView.
Thermal Durability of Electrospun Nanofibre Interleaved Composites. ABSTRACT Carbon fiber composites are susceptible to brittle damage modes such as matrix cracking and delamination. The inception and propagation of these invisible damages are responsible for loss in load‐bearing capacity and accelerating environmental degradation.

Experimental and Numerical Assessment of Progressive Damage in CF/PEEK Laminates Under Monotonic and Progressive Cyclic Four‐Point Bending

Polymer Composites, EarlyView.
Experimental four‐point bending of CF/PEEK laminates under monotonic and progressive cyclic loading is assessed using classical lamination theory and a calibrated Hashin progressive damage model. ABSTRACT Carbon‐fiber‐reinforced PEEK composites combine high specific strength, corrosion resistance, and damage tolerance, supporting their use in aerospace,
