A cooling fabric including a moisture-permeable inner surface layer, a spacer fabric and an outer surface layer, wherein the outer surface layer has an air permeability of at most 250 l/dm2/min at 500 Pa measured according to ISO 9237 and wherein the spacer fabric comprises monofilaments extending across the spacer fabric, wherein the monofilaments have a linear density of at least 250 dtex and wherein the monofilaments are present at a density of at most 800 monofilaments per square-inch.

Cooling fabric

A ballistic resistant article is provided along with a process to manufacture the article. The ballistic resistant articles includes at least one consolidated composite, wherein the at least one consolidated composite includes at least two layers, each layer includes a network of fibers, the fibers have a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07, the fibers in each layer are impregnated with a matrix material, and each consolidated composite has a front surface and a rear surface. In the ballistic article, at least the front surface of each consolidated composite is powder coated with partly molten and solidified powder particles to form a powder coated surface.

Ballistic resistant article and process to manufacture said article

A ballistic resistant article is presented comprising a plurality of fibrous layers, each of said layers comprising a network of fibers, wherein the fibers have a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07 and a matrix material, wherein the matrix material comprises a mixture comprising: at least one styrene butadiene random copolymer resin, and at least one tackifier. Compared with an article of the same construction but with a matrix material without a tackifier the article according to the invention comprises a higher adhesion between the fibrous layers both in the unaged and aged state and a lower water pick up after water soak. The article additionally comprising a plate of metal or ceramic exhibits minimal or even no delamination of the fibrous layers after ballistic attack. In contrast an article of the same construction but with a matrix material without the styrene butadiene random copolymer resin exhibits (very strong) interior delamination of the fibrous layers and the article of the same construction with the styrene butadiene random copolymer resin, but without the tackifier as the matrix material exhibits light delamination.

Ballistic resistant article comprising a styrene butadiene resin and process to manufacture said article

A ballistic resistant article is presented comprising a plurality of fibrous layers, each of said layers comprising a network of fibers, wherein the fibers have a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07 and a matrix material, wherein the matrix material comprises a mixture comprising at least one self-crosslinking acrylic resin and/or at least one crosslinkable acrylic resin, and at least one tackifier. Compared with an article of the same construction but with a matrix material without tackifier the article according to the invention comprises a higher adhesion between the fibrous layers both in the unaged and aged state and a lower water pick up after water soak and the article passes the gasoline soak test. The article additionally comprising a plate of metal or ceramic exhibits minimal or even no delamination of the fibrous layers after ballistic attack, whereas an article of the same construction but with a matrix material without tackifier exhibits interior delamination of the fibrous layers.
