Effects of Preform Density on Structure and Property of C/C-SiC Composites Fabricated by Gaseous Silicon Infiltration

The 3-D needled C/C preforms with different densities deposited by chemical vapor infiltration (CVI) method were used to fabricate C/C-SiC composites by gaseous silicon infiltration (GSI).The porosity and CVI C thickness of the preforms were studied, and the effects of preform density on the mechanical and thermal properties of C/C-SiC composites w

Two-Stage Robust Security-Constrained Unit Commitment Model Considering Time Autocorrelation of Wind/Load Prediction Error and Outage Contingency Probability of Units

The conservativeness of unit commitment models-based robust optimization (RO) depends on the modeling of uncertainty sets.This paper proposes a new two-stage robust security-constrained unit commitment (SCUC) model, which aims at minimizing the operating cost in the base scenario while guaranteeing that the robust solution can be adaptively and saf
