Elastic composite structure
The invention relates to an elastic composite structure, which is intended for use as a flexible, pliable and thin film structure in the manufacture of a 2- or 3-dimensional product, particularly for providing mechanical protection against cutting, puncturing and/or the like. The composite structure comprises firstly an elastomer system (1), which is constituted by at least one PUR- (polyurethane resin), PUD- (polyurethane dispersion), SI- (silicone) based elastomer material and/or the like, and secondly by a mechanically durable reinforcer system (2), such as a fabric, weave or knit structure (2a) made from one or more flexible hybrid yarns, an oriented flake reinforcement structure (2c) made from laminated flakes (y), and/or the like. The invention relates also to an elastic composite structure, which is intended for the above application and which comprises a reinforcement system (2) for reinforcing the same mechanically against cutting, puncturing and/or the like. In this respect, the composite structure's reinforcement system (2) is manufactured as a flake reinforcement composition, consisting of hard organic and/or inorganic components (y) and comprising at least one co-laminated hard polymer layer and an elastomer matrix (2; 2b) applied integrally in contact therewith.
Non-combustible, breathable membrane
A coated textile contains a web based on glass fibres having a back face, a front face and at least one edge. The front face is covered with a coating layer based on silicone and back face is capable of being bonded to a support. The coating layer has a thickness between 5 m and 250 m and includes at least one inorganic flame retardant compound in a quantity which is sufficient for the coated textile to have a gross calorific value of less than or equal to 3 MJ/kg, the inorganic flame retardant compound having a D50 granule size of less than 50 m.
