Book ChapterDOI
SiC/SiC Composites for 1200°C and Above
TL;DR: In this article, the authors present information concerning processes and properties for five silicon carbide (SiC) fiber-reinforced SiC matrix composite systems recently developed by NASA that can operate under mechanical loading and oxidizing conditions for hundreds of hours at 1204, 1315, and 1427°C.
Journal ArticleDOI
Impact Resistance of Environmental Barrier Coated SiC/SiC Composites
TL;DR: In this article, the impact performance of 2D woven SiC/SiC composites coated with 225 and 525 microns thick environmental barrier coating (EBC) was investigated and the composites were fabricated by melt infiltration and the EBC was deposited by plasma spray.
Journal ArticleDOI
Impact resistance of uncoated SiC/SiC composites
TL;DR: In this paper, two-dimensional woven SiC/SiC composites fabricated by melt infiltration method were impact tested at room temperature and at 1316 C in air using 1.59mm diameter steel-ball projectiles at velocities ranging from 115 to 400 m/s.
Journal ArticleDOI
Role of Interfacial Carbon layer in the Thermal Diffusivity/Conductivity of Silicon Carbide Fiber-Reinforced Reaction-Bonded Silicon Nitride Matrix Composites
TL;DR: In this article, a combination of a carbon coatings on the fibers and an interfacial gap due to the thermal expansion mismatch in the composite can significantly lower the effective thermal diffusivity in the direction transverse to the fiber.
Journal ArticleDOI
Mullite–gadolinium silicate environmental barrier coatings for melt infiltrated SiC/SiC composites
TL;DR: In this paper, a slurry based mullite/gadolinium silicate (Gd 2 SiO 5 ) environmental barrier coatings (EBCs) were developed for melt infiltrated (MI) SiC/SiC composites.
