A method for determining personal protective equipment (PPE) comfort for an individual wearer includes defining a first anatomical shape data representative of an anatomical area of the individual wearer prior to donning a PPE, a second anatomical shape data representative of the anatomical area of the individual wearer after donning the PPE, and comparing the first anatomical shape data with the second anatomical shape data. The method further includes determining a soft skin tissue deformation at a plurality of predetermined anatomical positions based on the comparison between the first anatomical shape data and the second anatomical shape data, and determining a displacement comfort threshold (CTd) value based on the soft skin tissue deformation. The method also includes determining a pressure pain threshold (PPT) value, and determining a comfort metric based on the PPT values and the CTd values. The method also includes generating a notification corresponding to the comfort metric.

System and method for determining personal protective equipment comfort

There is provided a composite article comprising a composite material comprising 60 wt % to 98 wt % of a hydrolytically stable thermoplastic resin; and 1 wt % to 11 wt % long conductive metal fibers coated with a polymer selected from at least one of aromatic polycarbonates, aromatic polycarbonate alloys, aromatic polyethers, maleated polyolefins, semi-aromatic nylons, stabilized nylons, and combinations thereof.

Composite article

Described herein is a method of making silsesquioxane-like particles using polyhydrosiloxanes and a water soluble base. The silsesquioxane-like particles have an average particle diameter of less than 100 micrometers and are substantially free of &#x2014;OH bonds. In one embodiment, the silsesquioxane-like particles may be used in films.
