“…However, this processing route has to deal with the limitations of an increment in time consumption of approximately 30 to 50%, the emergence of excessive residual stress (resulting in issues such as composite core crush, skin pillowing, and dimpling), as well as elevated costs by 30 to 50% across capital, production, and operational expenses [4,[8][9][10]. These limitations have prompted researchers to explore alternative processing methods, with vacuum-bagging-only pre-forming and oven curing (VBO-oven curing) standing out as the most relevant shift, effectively eliminating the need for high pressure and the elevated costs of autoclave curing [11][12][13].…”

Autoclave-based production of composite laminates leads to extended time requirements, increased manufacturing expenses, and the accumulation of significant residual stress. These limitations have spurred research and innovation in seeking alternative out-of-autoclave (OOA) processing methods. The present study aimed to measure the impact of distinct and combined pre-forming parameters within the pre-forming process of vacuum bagging with oven curing (VBO-oven curing) on thickness, abnormalities, and void content in cured laminates of conventional, cost-effective glass/epoxy autoclave composite material. The abnormalities were analyzed using ultrasonic C-scan and thickness measurement was done to determine thickness variations. A burn-off test was employed to measure the void content. The relationship between processing parameters was subsequently investigated via analysis of variance (ANOVA). Higher thickness standard deviation was yielded at higher abnormality percentages in the C-scan results, resembling total discontinuities and non-uniformities. Voids were highest in the laminate produced via the standard pre-forming process. Edge breather, release wax, and intensifier reduced the void content by approximately 11.87%, 12.93% and 6.85%, respectively.

“…Oxide/Oxide ceramic matrix composites have seen significant advancement over the past few decades, due to their low density, high temperature capability and oxidative stability. [1][2][3][4][5][6] The mechanical properties of oxide/oxide composites are closely related to the properties of oxide fiber, especially after exposure at elevated temperatures. [7][8][9][10] All commercial polycrystalline oxide fibers used in oxide/oxide composites up to now are based on alumina.…”

The microstructure and mechanical properties of an alumina‐silica ceramic fiber after thermal exposure at 1100–1300°C were investigated by X‐ray diffraction, nuclear magnetic resonance, scanning electron microscopy, transmission electron microscopy analyses and room temperature tensile strength test. The results showed that the fiber was composed of γ‐A12O3 and amorphous SiO2. A phase reaction of γ‐A12O3 and amorphous SiO2 occurred when thermal exposure temperature exceeded 1150°C, and a new mullite phase formed. The grain size of the newly formed mullite increased with the increase of exposure temperature. Both the phase transition and grain growth of mullite had a significant impact on the mechanical properties of the fiber. Tensile strength of the fiber decreased slightly when thermal exposure temperature was below 1150°C, while the strength retention of the fiber decreased sharply to 65.36% as exposure temperature rose to 1200°C. A higher dispersion of tensile strength was also observed at higher exposure temperatures, as revealed by the Weibull statistical model.

This review paper aims to look at silicon-based ceramic matrix composites and infiltration-based approaches for them. There are many different types of infiltration-based manufacturing processes, each with its own set of features. The best technique is chosen depending on the needs and desired attributes. With these considerations in mind, any type of infiltration might be selected to meet the requirements. Silicon-based ceramics has been highly used in the fields of aerospace, medical, automobile, electronics, and other various industries so it is important to study about their applications as well. This review outlines the evolution of composites from early 7000 BCE to composites today and discussed about various infiltration techniques for manufacturing silicon based ceramic matrix composites. This article also gives the comprehensive review of general characteristics and mechanical properties of silicon-based composites used in a variety of engineering sectors. The application section entails the wide range of engineering fields with consideration of infiltration techniques, which would be helpful for researchers to study and correlate the different infiltration techniques for end applications.
