摘要:
Grid structure, such as a lattice or grid-stiffened structure and a process of manufacturing such a grid structure. Fiber material is laid up on a base tool to form intersecting ribs defining a grid with a plurality of cavities. In the same step fiber material is laid to form one or more; local substructures. Blocks are placed, at the positions of the cavities. The fiber material of the ribs and. the local substructures is impregnated with a resin. Optionally, one or more layers of fiber material are placed on the base tool and/or over the ribs and the blocks to form an outer skin. The ribs, the local substructure and optionally the outer skin jointly consolidated to form, the grid, structure.
摘要:
An item comprising at least one food contact zone (2) made of at least one fiber reinforcing laminar element (15) embedded within a polymer matrix (10). In particular, the latter includes at least one base layer (11) made of a first polymeric material and a food grade contact surface (12) that defines the food contact surface (2') of the zone (2). The polymer matrix (10) is optically transparent so as to allow an user to see the reinforcing element (15) therethrough (10).
摘要:
A condom assembly includes at least one of a condom, patch or glove made of at least one of natural latex, synthetic latex or the mixture of natural latex and synthetic latex. The natural latex, synthetic latex or the mixture of natural latex and synthetic latex contain prodrugs of nitric oxide and/or other active ingredients.
摘要:
Chemically anchoring long-chain polymer networks of tough hydrogels on solid surfaces can represent a general strategy to design tough and functional bonding between hydrogels and solid materials, achieving interfacial toughness over 1000 Jm-2.
