Material Characterization

ARIES WP17 Members · Zenodo (CERN European Organization for Nuclear Research) · 2018

One of the main objectives of the PowerMat work-package is the development and characterization of novel and advanced materials for demanding thermal management applications and high-energy particle accelerators. In this document, we present the comprehensive characterization campaigns performed at CERN, GSI and Polimi on a broad spectrum of advanced materials, including recent grades of Molybdenum Carbide – Graphite (MoGr), Thermal Pyrolytic Graphite (TPG), several grades of Carbon Fibre reinforced Carbon (CFC), Isotropic Graphites, Carbon Foams, Glassy Carbon (GC), Copper – Diamond (CuCD), with and without thin-film coatings.

Material Characterization System.

Gilbert F. Lee, Bruce Hartmann · 1994

Abstract : A plurality of elongated test specimens undergo vibrations induced by random noise within an acoustical frequency range establishing standing waves therein having resonant frequencies at which the collection of measurement data through accelerometers mounted at the ends of the specimens provides for calculation of physical material properties. The processing of the data during collection, analysis and calculation is automated by programmed computer control. (MM)

characterization Material failure

Mooney Viskositaè T Naturkautschuk · 2015

The standard Mooney measurement has been used for more than fifty years to characterize the rheological properties of natural rubber. According to interna-tional specifications, the Mooney viscos-ity of a material is the torque value read after subjecting the sample to shearing for 4 minutes, at 2 rpm, in a particular geometry. In this study, the Mooney viscosity of masticated and raw natural rubber was examined by using a multiple rotor speed Mooney viscometer. The double-logarithmic flow curve shows a decrease in the slope, which is charac-teristic of a transition from a proper flow regime to material failure, also observa-ble by capillary rheometry. For all the samples studied, this transition takes place at rotor speeds lower than 2 rpm. These results suggest that standard Mooney measurements performed on natural rubber give misleading results. A Mooney characterization of natural rubber at lower speeds is recommended.

Balloon material characterization

James S. Wilbeck, J. L. Rand · 1981

Experimental data are reviewed to study the state of stress and strain in a typical balloon fabricated from thin polyethylene film. Relaxation tests are conducted over a temperature range of -60 C to 140 C for a constant strain of 1%, and loads measured with the load cell are converted to values of the relaxation modulus. A log-log plot is made of the modulus as a function of time, and the maximum stress is found to occur at times of the order of one-half second. The film behaves as a nonlinear viscoelastic material, and by examining various theoretical relationships of stress and strain with temperature and time histories, a material testing program is developed which yields the necessary data to characterize the film.

Carbonaceous Material Characterization

Gerardo Dı́az · 2022

The thermochemical conversion of biomass by means of processes such as torrefaction, pyrolysis, or gasification, produces a char-like material with properties that differ considerably from the original feedstock. Further processing in the form of chemical or physical activation continues to modify the properties of the carbonaceous materials produced. The following Sections (1.1.1–1.1.4) provide a description of the main properties needed to characterize carbon-based materials for applications of biochar production and energy conversion.

Nondestructive material characterization

Vance A. Deason · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 2023

A method and apparatus for nondestructive material characterization, such as identification of material flaws or defects, material thickness or uniformity and material properties such as acoustic velocity. The apparatus comprises a pulsed laser used to excite a piezoelectric (PZ) transducer, which sends acoustic waves through an acoustic coupling medium to the test material. The acoustic wave is absorbed and thereafter reflected by the test material, whereupon it impinges on the PZ transducer. The PZ transducer converts the acoustic wave to electrical impulses, which are conveyed to a monitor.

Carbonaceous Material Characterization

Gerardo Dı́az · 2022

The ever-increasing energy demand has forced the world to consider alternative energy sources, other than fossil fuels, as a long-term approach to energy generation and for the reduction of carbon emissions. Renewable energy sources such as solar and wind have significantly increased their penetration in the overall energy matrix; however, these sources suffer from intermittency and variability. Despite on-going efforts to increase storage capacity, there is currently no feasible technology for grid-scale storage of electricity. Among the available renewable energy sources, biomass has great potential to provide energy for the transportation (biofuels) and electricity sectors as a dispatchable resource. In addition, biomass conversion provides value-added products such as biochar, which can be utilized for soil amendment or as filtering material when post-processed into activated carbon. Biochar also represents a stable form of carbon capture, that prevents the release of carbon emissions to the atmosphere. Biomass either decomposes, releasing methane to the atmosphere, or it is burned in controlled fires or fast-spreading wildfires. Recent droughts and bark beetle infestation have generated very large amounts of dead trees, specially in forest areas such as the Sierra Nevada in California. The properties of biomass have a direct impact on thermochemical processes and therefore, each feedstock needs to be characterized in order to optimize conversion performance at processing plants. In addition, post-processing techniques, such as physical or chemical activation, require the characterization of the properties of biochar and the respective activated carbon produced. Conventional processing techniques, such as pyrolysis, gasification, or incineration, are affected by the thermophysical properties and chemical composition of the feedstock. However, when electric fields are applied, the dielectric and electrical properties of the material also become important. This chapter describes the relevant properties of biomass, biochar, activated carbon, and pyrolytic graphite.
