Characterization and Modeling Damage and Fracture of Prepreg-MI SiC/SiC Composites under Tensile Loading at Room Temperature

Hu Liu et al.

Summary: In this paper, the damage and fracture in SiC/SiC composites were investigated through AE signals analysis. A micromechanical damage-based constitutive relationship was developed to predict the nonlinear behavior and hysteresis loops. The associations between tensile behavior, hysteresis loops, and internal damage evolution with fracture were revealed through experimental and predicted results.

Phase-field cohesive zone modeling of multi-physical fracture in solids and the open-source implementation in COMSOL MULTIPHYSICS

Wan-Xin Chen et al.

Summary: Despite the popularity of phase-field models for fracture in purely mechanical problems, their application to multi-physics problems is less reported due to theoretical complexity and cumbersome implementation. In this study, the phase-field cohesive zone model is adopted to address fracture in various multi-physics problems and open-source implementations are presented in COMSOL MULTIPHYSICS. Validation shows that PF-CZM can well capture typical fracture characteristics in multi-physics problems.

On microscopic analysis of fracture in unidirectional composite material using phase field modelling

Sagar Rao et al.

Summary: This study fills the gaps in understanding the implications and requirements of using the phase-field model (PFM) in studying fracture in composite materials. It analyzes the role of critical parameters, the effects of length-scale interactions, and concerns about convergence. By weakening the matrix/fibre interface, the PFM proves to be an important tool in toughening composite materials.

Rare earth monosilicates as oxidation resistant interphase for SiCf/SiC CMC: Investigation of SiCf/Yb2SiO5 model composites

Xirui Lv et al.

Summary: In this study, SiC fiber and Yb2SiO5 composites were processed using the Spark Plasma Sintering (SPS) method. Different types of interfaces were achieved by adjusting the sintering temperature. It was found that the thermal expansion mismatch between Yb2SiO5 and SiC led to high interface stress, and the high temperature and electric field also had an effect on the interface. The study suggests that introducing the Yb2Si2O7-Yb2SiO5 phase can adjust the interfacial parameters and optimize the mechanical properties of the material.

Single-source-precursor derived SiHfBCN enhancing oxidation resistance of SiC/SiC composites in wet oxygen

Xinming Xu et al.

Summary: SiC/SiC-SiHfBCN composites with enhanced wet oxidation resistance were obtained by modifying the semi-dense SiC fiber reinforced SiC composites with single-source-precursor derived SiHfBCN ceramics. The wet oxidation behavior of SiC/SiC-SiHfBCN composites at 1200-1400°C in different atmospheres was investigated. It was found that the SiC-SiHfBCN ceramic matrix can provide damage-free protection for SiC fibers up to 1300°C in wet oxygen for at least 100 hours.

Single-source-precursor synthesis and high-temperature evolution of a boron-containing SiC/HfC ceramic nano/micro composite

Qingbo Wen et al.

Summary: An amorphous ceramic containing boron, SiHfC(N,O), was synthesized through pyrolysis of a single-source precursor in Ar atmosphere at 1000 degrees C. High-temperature annealing resulted in the formation of HfCxN1-x nanoparticles and beta-SiC crystallization, with the eventual generation of HfB2 at temperatures beyond 1900 degrees C. The addition of boron increased the sintering activity of SiHfC(N,O) and led to the production of dense materials with improved mechanical properties compared to boron-free SiC/HfC.

Tunable strength of SiCf/β-Yb2Si2O7 interface for different requirements in SiCf/SiC CMC: Inspiration from model composite investigation

Xirui Lv et al.

Summary: Model composites with tunable SiCf/Yb2Si2O7 interfaces were processed by Spark Plasma Sintering, achieving weak and strong interfaces at different sintering temperatures. Different debonding mechanisms were observed in indentation crack test, with weak interfaces showing crack deflection and low debond energy compared to strong interfaces. The strong interface demonstrated high debond energy and crack penetration, promising improved performance under higher combustion temperature. Adjusting interfacial strength or debond energy could optimize the mechanical fuse mechanism in SiCf/SiC CMC.

A phase field formulation for dissolution-driven stress corrosion cracking

Chuanjie Cui et al.

Summary: In this study, a new theoretical and numerical framework for modelling mechanically-assisted corrosion in elastic-plastic solids is presented. The model successfully captures pitting and stress corrosion cracking, as well as the pit-to-crack transition. For the first time, the role of mechanical straining as the electrochemical driving force is incorporated. The use of a phase field paradigm helps in accurately approximating complex SCC morphologies.

In situ X-ray tomography characterisation of 3D deformation of C/C-SiC composites loaded under tension

Yang Chen et al.

Summary: C/C-SiC composites fabricated through Liquid Silicon Infiltration were tested under monotonic tension with in situ X-ray computed tomography. The 3D XCT images provided explicit visualisations and quantitative measurements of the distributions of SiC-Si and the orientations of the C fibre bundles. Strong local deformations, observed at both low and high applied stresses, were mostly in the through-thickness direction, indicating local delamination, highlighting the importance of residual stresses to damage development in C/C-SiC composites.

Summary: A ground-based evaluation was conducted on the resistance capability of a HfC-modified C/SiC composite against high-speed atomic oxygen in a low Earth orbit simulating system. Various analytical techniques were used to investigate the damage behaviors, products, and mechanisms of the material exposed to atomic oxygen. The study revealed that the material exhibited different responses in different areas, with HfC areas oxidizing preferentially and SiC areas showing lower surface damage.
