Beads may be stitched to a substrate layer and then fused to form structures including foam midsoles, foam pads, and other foam structures. Beads may be embroidered to multiple substrate layers and then folded or stacked together to form a preform used in a mold to form a midsole.

A microlattice structure may be used for a variety of different applications with a protective helmet assembly. The three-dimensional microlattice layer comprising a plurality of interconnected filaments extending along at least three different directions from a plurality of nodes. The microlattice layer may further comprise at least one material layer extending laterally between and interconnecting at least two or more nodes. The at least one material layer may be configured to transversely and rotationally constrain the nodes to increase the overall compressive strength and stiffness of the microlattice structure. The at least one material layer may comprise a single, continuous layer and/or a plurality of material layer segments. The microlattice layer may comprise a single, continuous layer or a plurality of microlattice layer segments. The microlattice layer may be stacked, the stacked microlattice layers may further comprise one or more material layers and/or one or more impact mitigation layers.

A lattice structure includes multiple identical unit cells formed from joined plates. In the lattice structure, some of the plates are rectangular plates, some of the plates are triangular plates, and some of the plates are trapezoidal plates. Further, any two of the joined rectangular plates have corresponding surface normals perpendicular to each other and at least two edges of each one of the triangular plates are joined to one of a surface or an edge of one of the plurality of joined plates. Further, at least three edges of each one of the trapezoidal plates are joined to one of a surface or an edge of one of the plurality of joined plates, and any one of a plurality of surface normals for the triangular plates and the trapezoidal plates are nonparallel to any one of a plurality of surface normals of rectangular plates.

Adhesive compositions that include polymerized units of one or more (meth)acrylate ester monomers derived from an alcohol containing 1 to 14 carbon atoms; polyvinyl acetal resin; and at least one initiator; and articles containing such compositions.

The invention relates to a composite sheet, and a ballistic resistant article, comprising unidirectionally aligned high performance polyethylene (HPPE) fibers and a polymeric resin, wherein said polymeric resin comprises a homopolymer or copolymer of ethylene and wherein said polymeric resin has a density as measured according to ISO1183 of between 930 and 980 kg/m3, and a peak melting temperature of from 115 to 140° C.; and said polymeric resin is present in an amount of from 5 to 25% by weight based on the total weight of the composite sheet. It further relates to a method for manufacturing a composite sheet comprising assembling HPPE fibers to a sheet, applying an aqueous suspension of a polymeric resin to the HPPE fibers, partially drying the aqueous suspension, optionally applying a temperature and/or a pressure treatment to the composite sheet.

A biofabricated material containing a network of crosslinked collagen fibrils is disclosed. This material is composed of collagen which is also a major component of natural leather and is produced by a process of fibrillation of collagen molecules into fibrils, crosslinking the fibrils and lubricating the crosslinked fibrils. Unlike natural leathers, this biofabricated material exhibits non-anisotropic (not directionally dependent) physical properties, for example, a sheet of biofabricated material can have substantially the same elasticity or tensile strength when stretched or stressed in different directions. Unlike natural leather, it has a uniform texture that facilitates uniform uptake of dyes and coatings. Aesthetically, it produces a uniform and consistent grain for ease of manufacturability. It can have substantially identical grain, texture and other aesthetic properties on both sides distinct from natural leather where the grain increases from one side (e.g., distal surface) to the other (proximal inner layers).

Generally described, aspects of the disclosed subject matter are directed to impact mitigating membranes. In accordance with aspects of the present disclosure, the impact mitigating membranes generally include a laminar core having a first lamina and a second lamina coupled to the first lamina and configured to shift relative to the first lamina to dissipate kinetic energy resulting from an oblique impact force. The laminar core may include a lubricating layer or self-lubrication between the lamina to reduce friction. In general, the laminar core is surrounded by first and second encapsulating layers positioned adjacent each lamina. An anchoring attachment coupled to one or more of the first and second encapsulating layer and associating with the laminar core constrains relative lateral motion between the laminar core and the first and second encapsulating layers.

A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce porosity-free castable resins and vulcanize rubber formulations based on epoxidized natural rubber. Materials made from disclosed materials may be advantageously used as leather substitutes.
