Effect of microwave sintering time on the flexural properties of the SiC/SiC composites

In situ investigation of failure in 3D braided SiCf/SiC composites under flexural loading

“…The higher effective modulus of the Series 2 composite compared to the Series 1 material, obtained prior to the development of visible damage, is consistent with the higher stiffness of the KD-Ⅱ SiC fibres [47][48]. This is also consistent with the observation in [54] that SiC fibres significantly affect the flexural properties of SiC/SiC composites. However, differences may also arise from development of the matrix via PIP with alternative precursors (Table 1).…”

“…The effective flexural modulus difference between Series 1 is quite significant. This may be due to a larger property variations of KD-I fibres [54], but also may arise from heterogeneity of the braided composite microstructure (such as the pores) and the small thickness of the test specimens, which limits the strained volume.…”

Influence of Carbon Inclusion on the Electrochemical Performances for Si Using as the Lithium-Ion Battery Anode

“…High-energy anode materials have attracted significant attention because of high energy density, broad operating temperature range, low self-discharge rate, long cycle life, high voltage, and no voltage depression [1,2]. However, commercially-used graphite anode material has a low specific capacity, the theoretical capacity of 372mAh/g [2], currently, there are an important direction of the lithium ion battery of looking for a higher specific capacity of anode materials. Si has emerged as a promising anode material due to its huge theoretical specific capacity (4200mAh/g) [3,4], low working potential (about 0.5 V vs Li/Li +) and has low price.…”
