As a rock mass with shallow burial, high temperature, and large-scale development, the study of its mechanical seepage characteristics plays an important role in efficient development geothermal energy. With energy China, breakthrough has been made exploration dry-hot rocks, realization rocks become focus attention. Systematic research on mechanics key topic. Granite is most typical rock. In th...

semiconducting carbon nanofibers (cnf) are prepared from three different sources, i.e., acetylene, ethanol, and cotton by the chemical vapor deposition (cvd) process. these fibers are having rich elastic, engineering and conductivity properties. fresh self-compacting concrete (scc) flows into place and around obstructions under its own weight to fill the formwork completely and self-compact, wi...

in this work, leather fibers were employed as a component of elastomeric compounds based on nbr, cr and epdm and studied were made on their effects upon curing characteristics and mechanical properties of the prepared compounds. evaluation of curing characteristics of the compounds demonstrated that leather fibers have no considerable effect on initial viscosity and curing time of the compounds...
