The effect of neutron irradiation on the fiber/matrix interphase of silicon carbide composites

Evaluation of damage accumulation behavior and strength anisotropy of NITE SiC/SiC composites by acoustic emission, digital image correlation and electrical resistivity monitoring

“…Due to the high modulus of the fiber and the rough high-crystalline SiC fibers [8], sliding was hardly expected owing to strong clamping at the F/M interface even when cracking. Higher frictional stress for rough surfaced Tyranno-SA3 fiber composites may support this hypothesis [9]. Under this situation, a large portion of the weak matrix region was stressed, resulting in locally concentrated damage accumulation [5].…”

Initial assessment of environmental effects on SiC/SiC composites in helium-cooled nuclear systems

“…Indeed, the effect of neutron irradiation on composites with different type of interphase (either single layer PyC or multilayer PyC-SiC) showed better performance of multilayer composites with thin innermost PyC layers. 56,57 As mentioned above, composites with multilayered interphases have the advantage of higher oxidation resistance overt those with one single PyC layer. 47,49 The oxidation resistance of irradiated SiC/SiC composites has not been reported yet, and is currently an active direction of research.…”

Three-phase model and digital image correlation to assess the interphase effect on the elasticity of carbohdyrate polymer-based composites reinforced with glass–silica beads

“…For example, Biliaderis, Lazaridou, and Arvanitoyannis (1999) have shown that Young's modulus of starch-based blends decreases when the water content in the material increases. The measurement of the interphase properties is accessible experimentally using classical methods such as pull out, push-out tests (Chandra & Ananth, 1995;Chandra & Ghonem, 2001;Nozawa, Katoh, & Snead, 2009) and fragmentation test (Johnson, Hayes, & Jones, 2009;Tripathi & Jones, 1997;Zhou, Wagner, & Nutt, 2001), particularly for fibre-reinforced materials. Local measurement based on indentation are also utilised preferentially for thin films (Chicot, Démarécaux, & Lesage, 1996;Dehm, Ruhle, Conway, & Raj, 1997;Ho & Dual, 1996;Kharrat, Chateauminois, Carpentier, & Kapsa, 1997;Lee, Wang, Pharr, & Xu, 2007;Li & Siegmund, 2004;Zhang, Chen, & Li, 2004;Zhu & Bartos, 1997).…”
