The refractory composite materials have been widely used in engineering,It has great theoretical significance and applicational value to study the coupled effect for thermal and mechanical loading of this materials, especially the themoelastic problem of inclusion with various micro structure defects.
Single crystal α-Al2O3, (sapphire) fibers of ~ 100 μm diameter have recently emerged as candidates for stiffening and strengthening high temperature composites.
The strength and coefficients of friction of new heat-resistant composite materials consisting of metallopolymers of iron and cobalt based on molybdosilicic and tungstosilicic heteropolyacids have been studied.
These results suggest that extended cure times or high temperature post-curing may be required to obtain the resin's ultimate mechanical properties for high performance composites.
This method was applied to carbon and PVA fiber reinforced high performance composites and was used to optimize the rheological properties of these composites for an application in a centrifugation casting process.
The chemical composition and the structural parameters and mechanisms that control the oxidative and thermal stabilities of PAN-based C6000, IM6 and T300 carbon fibres used in high performance composites are reported.
