US12332028 - Composite material

A composite material ( 10 ) comprising: a base layer ( 48 ); a plurality of protective plates ( 41, 51, 51 a, 51 b ) located on the base layer ( 48 ); an attaching means ( 43 ) to connect the base layer ( 48 ) to the protective plates ( 41 ), wherein the attaching means ( 43 ) is positioned along a first direction ( 46 ) on the base layer ( 48 ) to resist pivoting of each protective plate ( 41, 51, 51 a, 51 b ) about an axis normal to the base layer ( 48 ).

The patent describes a cut and puncture resistant composite material that includes an elastic layer and multiple protective elements, each attached in a way that minimizes misalignment while preserving elasticity. The design ensures that the attachment areas are significantly smaller than the protective elements’ surface areas, enhancing the overall functionality of the material.

Claim 1

A cut and puncture resistant composite material comprising; at least one elastic layer, at least two protective elements each having a smaller surface area than the surface area of said elastic layer, at least one attachment between each said protective element and said elastic layer, wherein the surface area of each attachment is substantially smaller than the total surface area of each protective element; and wherein an attachment area between each said protective element and said elastic layer is at least 1/12 of the perimeter length of each protective element and the attachment area between each said protective element and said elastic layer is less than 50% of the total area of each said protective element, wherein each attachment substantially restricts the misalignment of each protective element relative to the elastic layer while maintaining substantial elasticity. at least one elastic layer, at least two protective elements each having a smaller surface area than the surface area of said elastic layer, at least one attachment between each said protective element and said elastic layer, wherein the surface area of each attachment is substantially smaller than the total surface area of each protective element; and wherein an attachment area between each said protective element and said elastic layer is at least 1/12 of the perimeter length of each protective element and the attachment area between each said protective element and said elastic layer is less than 50% of the total area of each said protective element, wherein each attachment substantially restricts the misalignment of each protective element relative to the elastic layer while maintaining substantial elasticity.
