Abstract:
A method for laminating or coupling a first and second precision fabric layers each being formed by weaving a plurality of synthetic monofilaments to achieve a two-layer textile structure, for application to loudspeakers and microphones of electronic devices in general providing at least an audio function, either a sound emitting (voice or music) or receiving function, both for protecting said electronic device from water and solid particle intrusion and for preserving the designed sound emitting and receiving characteristics, the method comprising coupling the first and second layers by a glueing material sprayed on the synthetic monofilaments of at least one of the first and second precision fabric layers.
Abstract:
A method for making a composite board, wherein a layered structure is manufactured, which comprises three three- dimensional fabrics overlapping each other, impregnated with resin ans interposed between a pair of detaching sheets. The layered structure is compressed by means of a heated press, so that the resin can spread uniformly. Subsequently, the layered structure is allowed to expand, so that the filaments of the three-dimensional fabrics stretch and arrange themselves substantially perpendicular to the laying planes of the fabric sheets forming the three-dimensional fabrics. After the polymerization of the resin impregnating the layered structure, the latter is taken out of the press and the detaching sheets are removed, thus obtaining a finished board.
Abstract:
A flexible textile or cloth is provided that can be hardened to a rigid or semi-rigid condition. The textile can incorporate reinforcement fibers to provide improved mechanical properties. The reinforcement fibers can be added in a various configurations without unnecessarily increasing the weight of the textile. Further, the textile can include at least one flap to facilitate readily joining the textile with another component such as another textile to create a composite construction.
Abstract:
A laminate includes a metal substrate and a sliding layer overlying the metal substrate. The sliding layer can include a polymer fabric. The polymer fabric can include first polymer P1. The sliding layer can further included a melt-processable matrix polymer. The melt-processable matrix polymer can include a second polymer P2. In embodiments, either P1 or P2 is a fluoropolymer. The sliding layer can further include a filler. In embodiments, the total amount of fluoropolymer and filler in the sliding layer is at least 30 vol%.

Abstract:
A thin elastomeric laminate 26 can be made by bonding two bilaminate precursors 24 and 25. The bilaminate precursors 24, 25 are made from a thin elastomeric film 20 laminated to a thin nonwoven fabric 13. Two layers of bilaminate precursor 24, 25 are then bonded such that the free film faces of both precursors are facing one another. The resulting laminates 26 exhibit good robustness and resist the formation of activation pinholes.
Abstract:
El sistema comprende un soporte (1) con un marco (2), donde se sitúa la capa de tejido poroso (3) que se pretende manipular para situarla sobre otra capa de tejido poroso (3') previamente situada en una estructura de soporte general (9) y formar, mediante varias capas, una pieza de tejido. También incluye un elemento de trasporte (8) relacionado con un generador de flujo de aire (5) para conseguir tanto el trasvase de la capa de tejido poroso (3) desde el soporte (1) con el marco (2) hacia ese elemento de trasporte (8), así como manipular y soltar esa capa de tejido (3) para situarla sobre la capa de tejido poroso (3') situada sobre la estructura de soporte general (9), estando el generador (5) capacitado de variar el sentido de giro del flujo de aire para producir una depresión o una presión dinámica durante el manipulado de la correspondiente capa de tejido poroso (3).
Abstract:
A printing method include steps: creating a 3D image corresponding to a to-be-printed image; sticking a film to a transparent sheet by removable glue; printing the 3D image on an inner surface of the film; adhering an elastic layer to the film by water based adhesive; modeling the printed film to form 3D model by vacuum plastic-absorbing machine; adding silica gel to the elastic layer to finalize the design. The printing product includes a film being printed with 3D image, an elastic layer adhered to the film by water based adhesive, silica gel added to the elastic layer for finalizing the design. As a result, the printing product is color printed with high definition, and the coating area on the 3D model is not limited. Furthermore, because the color layer is protected, the color on the 3D model is not prone to wear.
