Future collider detectors, including silicon tracking detectors planned for the High Luminosity LHC, will require components and mechanical structures providing unprecedented strength-to-mass ratios, thermal conductivity, and radiation tolerance. This paper studies carbon foam used in conjunction with thermally conductive epoxy and thermally conductive tape for such applications. Thermal performance and tensile strength measurements of aluminum-carbon foamadhesive stacks are reported, along with initial radiation damage test results.
Future tracking detectors, such as those under development for the High Luminosity LHC, will require mechanical structures employing novel materials to reduce mass while providing excellent strength, thermal conductivity, and radiation tolerance. Adhesion methods for such materials are under study at present. This paper demonstrates the use of reactive bonding film as an adhesion method for bonding carbon foam.
Abstract-With the frequent occurrences of the violence incidents, research on body armor is paid much attention to. To study the human physiological responses when wearing body armor and to improve the wearing comfort of body armor, a thermal manikin was used to measure the thermal insulation and vapor resistance of two types of body armor (stab-resistance and bulletproof, respectively) in a climate chamber. Results show the coverage levels on body part and material selections on protection layer affect the thermal insulation and vapor resistance of the body armors. Moreover, air temperature and relative humidity of the climate chamber have an influence on the moisture transfer of the body armors. The findings in this study could establish a data support for body armor, with thermophysical property improvement and design optimization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
