Abstract:

Carbon-carbon composites are deemed as candidate materials for application in very high temperature reactors. In a very high temperature reactor, carbon-carbon composite materials would experience severe environmental impacts from high temperatures. As a result, we applied non-destructive ex-situ diffraction experiments to investigate the microstructure changes of the carbon-carbon composite materials experiencing different temperatures. In this study, the samples were prepared in a format of a three-dimensional pitch-based carbon-carbon composite. The samples were heated to 500 (°C), 700 (°C)

Abstract:

With the increased use of carbon fiber reinforced polymer (CFRP) composites in civil infrastructure, understanding the fire structural performance of these materials is an important safety issue. In this paper, the effect of temperature on the tensile strength of carbon fibers and carbon/epoxy composite sheets was experimentally determined from 20°C to 500°C. Meanwhile, in order to better understand the strength degradation of carbon fiber-polymer composites at elevated and high temperatures, the tension tests were also performed for pure epoxy resin and CFRP sheets by means of 10°C off-axis a

Oil-well equipment for oil production operates under complex and changing circumstances. Well pressure and temperature can reach 100 MPa and 200 °С. Chemicals are pumped into oil-wells to enhance oil yield. However, this leads to an accelerated corrosion and contributes to the equipment breakdown. Adverse effects on the equipment can be decreased through use of protecting coatings with multi-function properties.Epoxy coatings are popular. However, they are limited by operating temperature of 130 °C. If the temperature is exceeded, epoxy coatings lose their protective properties. However, resea

Abstract:

To improve the oxidation resistance of carbon/carbon composites at high temperatures (>1770 K), they were coated with MoSi2-Si3N4/SiC. The slurry and pack cementation methods were adopted to deposit the inner SiC layer and outer MoSi2-Si3N4 layer. The phase composition, microstructure, and elemental distributions in the coating were analyzed using SEM, XRD, EDS, and Raman spectroscopy. Oxidation tests show that the deposited multi-layer coating can protect the carbon/carbon matrix from oxidation at high temperatures (>1770 K) for 150h and that the coating can withstand 40 thermal cycles

Carbon nanosheets (CNSs) reinforced copper composites are obtained with a molten salt route for uniform distribution of carbon in the copper matrix. The structures and properties of the composite are thoroughly characterized and tested. The mechanical properties of the composite are greatly improved compared to pure copper. The effects of annealing temperatures and carbon contents on the mechanical properties of composites are investigated and discussed. When the annealing temperature is 800∘C, the composite has excellent comprehensive properties. Its yield strength is 283 MPa, which is 3.14 t

Abstract:

The fire remains one of the serious potential risks to most buildings and structures, as recently it’s been witnessed in Paris’ historic Notre Dame Cathedral and London’s Grenfell Tower. Concrete and masonry construction materials suffer physiochemical changes and mechanical damage caused by heating that is usually confined to the outer surface but can eventually compromise their load-bearing capacity. FRCM systems could provide when applied, supplemental fire insulation on pre-existing structural members, but there is a lack of knowledge about their properties in those conditions. This experi

The influence of boric acid content in the matrix on the tensile strength, Young’s modulus and interlaminar strength of composites was studied.

The effects of space environment temperatures on specific carbon fiber/bismaleimide composite laminates were evaluated using the simulated environment test method. The tests were performed at −120 ℃, room temperature, 150 ℃, 170 ℃, and 200 ℃. The material responses were characterized through an assessment of mechanical properties including tensile, compressive, and in-plane shear properties. The experimental results showed that transverse tensile/compressive and in-plane shear responses, which are strongly related to matrix properties, were sensitive to temperature especially high temperature

The short carbon fiber reinforced 2024 Al composites were fabricated through powder metallurgy. The effect of short carbon fiber content on the interfacial microstructure and fracture behavior of the composites at different temperatures were investigated. The results showed that the dislocation accumulation was formed in the aluminum matrix due to the thermal expansion mismatch between carbon fiber and aluminum matrix. With the testing temperature increasing, the size of interfacial product Al4C3 and precipitates Al2Cu became larger, and the segregation of Al2Cu was found coarsening around Al4

Abstract:

Abstract Existing C-0.5Mo steel equipment in hydrogen service is still a concern in industries due to its high susceptibility to hydrogen attack at elevated temperature. High Temperature Hydrogen Attack (HTHA) has been one of the major problems in petroleum and petrochemical industry because of its metal degradation phenomena. HTHA occurs in carbon and low carbon steels exposed to high partial pressure of hydrogen at elevated temperatures. Since the original Nelson Curve was published in 1949 to define the operating limits for steels used in hydrogen service to avoid HTHA, a number of research

Abstract:

Thermal characterization of composites is essential for their proper assignment to a specific application. Specific heat, thermal diffusivity, and thermal conductivity of carbon-carbon composites are essential in the engineering design process and in the analysis of aerospace vehicles, space systems and other high temperature thermal systems. Specifically, thermal conductivity determines the working temperature levels of a material and is influential in its performance in high temperature applications. There is insufficient thermal property data for carbon-carbon composites over a range of tem

Abstract:

Abstract In this paper we discuss the effect of volumetric ablation on the overall elastic properties of the carbon fiber reinforced polymer matrix composite. An Arrhenius type equation describing polymer decomposition was used to determine volume fractions of evolving polymer matrix phases (i.e. polymer, growing pores filled with pyrolysis gases, and char). The effect of the pressure exerted by pyrolysis gases trapped inside the pores was analyzed. Microstructures consisting of carbon fibers (circular inclusions) in the matrix and pores (elliptic inclusions) in the polymer were generated. Tem

Abstract:

Carbon fiber reinforced polymer (CFRP) composites are commonly used in high-temperature applications; however, their performance is limited by their inability to withstand extreme temperatures, leading to degradation and failure in demanding environments. This paper demonstrates the benefits of thin, light weight, Thermal Protection Systems (TPS) that use polyimide aerogel films as the core insulating technology. The laminate TPS offer robust performance across a wide range of transient thermal events, effectively extending the operational limits of CFRP composites for space, aerospace, and ot

Abstract:

COVID-19, caused by the SARS-CoV-2 virus, was first reported in China in December 2019. The virus has spread rapidly around the world and is currently responsible for 500 million reported cases and over 6.4 million deaths. A risk assessment published by the Foods Standards Agency (FSA) in 2020 (Opens in a new window) concluded that it was very unlikely that you could catch coronavirus via food. This assessment included the worst-case assumption that, if food became contaminated during production, no significant inactivation of virus would occur before consumption. However, the rate of inactiva

Abstract:

Cellulosic-coated electrodes (primarily AWS EXX10-type) are traditionally used for stovepipe welding of pipelines because they are well suited for deposition of one-sided welds and are capable of high deposition rates when welding downhill. Despite advances in mechanized welding technology and the development of low-hydrogen consumables suitable for pipeline girth welding, manual welding, using cellulosic-coated electrodes is still widely utilized for pipeline construction throughout the world. Several incidents involving significant hydrogen-assisted cracking in the weld metal of pipeline gir
