The term manikin refers exclusively to these types of models, though mannequin is often also used. In first aid courses, manikins may be used to demonstrate methods of giving first aid (e.g., resuscitation). Fire and coastguard services use mannequins to practice life-saving procedures. The mannequins have similar weight distribution to a human.
A thermal manikin being used to test helmet padding. The thermal manikin is a human model designed for scientific testing of thermal environments without the risk or inaccuracies inherent in human subject testing. Thermal manikins are primarily used in automotive, indoor environment, outdoor environment, military and clothing research. The ...
The tight weave of Beta cloth makes it more resistant to atomic oxygen exposure. [2] Its ability to resist atomic oxygen exposure means it is commonly used as the outer-most layer of multi-layer insulation for space; it was used on the Space Shuttle and the International Space Station.
The insulation qualities of clothing materials are determined by the amount of "dead air" they can hold. The air is held in the voids inside the material itself as well as in the gaps between the clothing layers. Of the natural clothing materials, fur and leather provide the best insulation.
Double cloth or double weave (also doublecloth, double-cloth, doubleweave) is a kind of woven textile in which two or more sets of warps and one or more sets of weft or filling yarns are interconnected to form a two-layered cloth. [2] The movement of threads between the layers allows complex patterns and surface textures to be created.
West German army uniforms from the 1960s until the early 1990s were made of "moleskin" fabric in a greyish olive-drab colour, but the German moleskin was not shorn and thus had a flat, smooth outer side. Nonetheless, it was a tough, densely woven material, strongly resistant to wind and abrasion.
A Langmuir monolayer or insoluble monolayer is a one-molecule thick layer of an insoluble organic material spread onto an aqueous subphase in a Langmuir-Blodgett trough. Traditional compounds used to prepare Langmuir monolayers are amphiphilic materials that possess a hydrophilic headgroup and a hydrophobic tail.
Multiple layers and patches of the two materials were used to control the overall mechanical pressure around the body. Starting at the skin, a "slip layer" of light powernet was used to allow the outer layers to slide over the skin without binding.
