Summary: The tensile-tension fatigue behavior of minicomposite SiC/(PyC/SiC)2/SiC at room temperature was studied, and the residual mechanical properties of specimens were tested after 106 pre-fatigue cycles under different stress levels. It was found that the residual strength initially increases due to stress concentration release and then decreases because of excessive fiber wear. Additionally, the tensile curve of pre-fatigue specimens showed two deflections, with the first correlated with matrix crack reopening and the second occurring when the uniaxial tensile load exceeds the pre-fatigue stress.

Summary: A series of experiments were conducted to investigate the PyC interphase growth mechanism on T-300TM and T-700TM carbon fibers deposited by chemical vapor infiltration (CVI). Characterization techniques including AFM, SEM, TEM, XRD, Raman spectroscopy, and nanoindentation tests were used to analyze the microstructures. Numerical simulations were employed to establish the relationships between fabrication parameters, R (C2/C6) value, texture type, and interphase thickness. Hardness and modulus of PyC for T-300TM and T-700TM carbon fibers were measured. The tensile behaviors of C/SiC composites with different PyC interphases were analyzed, and the composite with medium texture PyC interphase showed better performance.

Summary: The study introduces a simplified approach to correlate the experimental tensile strength values of randomly oriented short fiber reinforced polymer-based composites, deriving a constitutive model based on a rule of mixtures. The experimental results demonstrate the significant influence of fiber orientation and interfacial stress on the composite's tensile strength, with the proposed model showing good agreement with experimental data. The analytical model outperforms other models in accurately predicting the behavior of short fiber reinforced composites.

Summary: In this study, the aging behavior of Cf(Ni)-ZrC/2024Al composites with a quasi-network structure was carefully investigated. The results showed that the addition of carbon fibers and ZrC particles allowed the composites to reach peak-aged condition in a shorter time and exhibit improved hardness, yield strength, and tensile strength compared to the monolithic 2024Al alloy. TEM observations revealed that the size and number of precipitated phases exhibited a similar variation tendency to the mechanical properties of the composites.

Summary: By coating carbon fiber with TiO2, the mechanical properties of carbon fiber reinforced 7075 Al alloy material were enhanced at high temperature conditions. The tensile strength and strength/density ratio of the composite were found to increase after TiO2 coating, attributed to the transformation of carbon fiber failure mode.

Summary: Short fiber/polymer composites are increasingly used in high-temperature structures, with a temperature-dependent ultimate tensile strength model developed in this study considering the evolution of residual thermal stress, interface, fiber, and matrix performance, as well as the effects of fiber agglomeration and orientation distribution. The model's predictions are validated against experimental data, showing reasonable accuracy and providing insights for fabrication and design of such composites. Discussions on the quantitative effects of fiber agglomeration and interfacial shear strength on the ultimate tensile strength are also included.

Summary: Hexagonal BN fiber coatings and powders were prepared by pyrolysis of boric acid and urea in a hydrogen and nitrogen atmosphere. The appropriate mixing ratio of raw materials for desired BN composition and crystal structure was investigated, resulting in hexagonal BN with near-stoichiometric composition. Coatings applied on SiC filaments showed crystalline BN layers without significant bridging in fiber bundles, as confirmed by SEM/EDS and grazing incidence x-ray diffraction analysis.

Summary: In this study, PyC coating with different thickness was prepared on SiC fibers, and the effects of PyC coating on the mechanical properties and high temperature performance of SiC fibers were investigated. The results showed that PyC coating could reduce the dispersion of tensile strength, inhibit Si sublimation, and improve the tensile strength retention of SiC fibers.
