Abstract We have designed and tested a device based on non-Newtonian fluids for the attenuation of tangential impacts energy in helmets. A shear thickening fluid borurated silicones has given best results terms impact system that selectively mimics this reason it been used to fill chamber pad, prepared by additive manufacturing, dissipation. The pad is composed case containing which immersed ri...

An EPS ventilated panel, which may be applied as an external insulation to humid walls, is investigated. Dimensions of the air channel sections have been determined using Ansys software. Afterwards, drying rate walls externally insulated with EPS, mineral wool and panel has compared WUFI The increases when standard polystyrene heat loss through wall by less than 20%.

In this study, alternative core materials to commercial cork were searched for. Additionally, aging of new was studied. Bio-based in sandwich structures can be useful for sports equipment, transportation, and furniture with much less impact on the environment comparison their synthetic counterparts. paper, panels made fiber-reinforced polymer (FRP) skins various sustainable a thickness 6 mm The...

Building envelope such as external walls are still constructed from poor materials which results in higher heating and cooling loads thereby raising energy bills. Improving building efficiency with advanced technologies is being sought. In this context, a numerical study was conducted to solve the coupled heat transfers through standard wall structure used Libyan residential buildings. Differen...

Plastic industry is ubiquitous worldwide, and the generation of “plastic waste” has been steadily increasing to point being considered a high impact pollutant. The expanded polystyrene (EPS) plastic aware issue interested on trying recycling post-consumer material. Through recent study made in an alliance between private sector academy, feasibility EPS “mechanical” was proven; therefore, possib...

fire behavior of different types of eps was evaluated with the use of iso 5660 cone calorimeter test method. considering the complexity of behavior of eps against high temperatures, several specimens were tested, so a betterjudgment on fire behavior of this material could be acquired. the effects of foam density, thickness of specimens and the level of heat flux on fire behavior of foam were ex...

This paper describes a calibrated broadband emitter for the millimeter-wave through terahertz frequency regime, called the aqueous blackbody calibration source. Due to its extremely high absorption, liquid water is chosen as the emitter on the basis of reciprocity. The water is constrained to a specific shape (an optical trap geometry) in an expanded polystyrene (EPS) container and maintained a...
