A manufacturing procedure for ceiling trims for vehicles. The ceiling trims comprise at least one first coating sheet and at least one second coating sheet that extend along one of the sides of the first sheet, joined via a layer of heat-stable polyurethane adhesive, comprising a step of applying a gas-phase catalyst on such sheets through a thermoforming mould that starts before the mould is completely closed and ends before the mould is completely opened. As a result of the application of a gas-phase catalyst we prevent the use of demoulding agents to facilitate extraction of the ceiling trim formed inside the mould.

The invention relates to a process for manufacturing a laminated material (S) comprising a fibrillated cellulose layer, characterized in that it comprises the following steps: (a) depositing a suspension (1) of fibrillated cellulose on a filtration membrane (2) and draining the suspension through that membrane so as to form a wet layer of fibrillated cellulose (A) having a dryness, that is to say a ratio between the mass of dry matter and the total mass of the fibrillated cellulose layer, of between 5% and 18%; (b) transferring the wet layer (A) under pressure to an at least partially hydrophilic surface of a substrate (B), so as to form the laminated material (S); (c) drying the laminated material. The invention also relates to a device for implementing the process.

A moisture detecting bleeder material includes a fiberglass material and a moisture absorption indicator material. The moisture absorption indicator material undergoes a color change from a first color to a second color when exposed to moisture. The color change thermally irreversible a temperature of 450 F.

An acidic gas separation membrane sheet causes an acidic gas to selectively permeate therethrough. The acidic gas separation membrane sheet includes a first porous layer, a hydrophilic resin composition layer, and a second porous layer in this order. A second peel strength between the second porous layer and the hydrophilic resin composition layer is less than a first peel strength between the first porous layer and the hydrophilic resin composition layer. An average value of the second peel strength is within a range of greater than or equal to 5 N/m and less than or equal to 500 N/m.

A method for repairing aircraft window laminates in which two plies have become separated to create a void, and wherein moisture may have entered through an edge of the window laminate and into the void. The method includes the steps of: placing the window laminate in a vacuum bag and inserting the vacuum bag containing the window laminate into an oven or autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove the moisture between the plies; removing the vacuum bag and window laminate from the oven, and removing the window from the vacuum bag; forcing a needle on a syringe through the edge of the window laminate in the area of the void; and injecting an adhesive in the syringe into the void to fill the void with the adhesive.

A timber composite with timber layers and an adhesive matrix, wherein the timber layers include a wood grain with both summer wood grain and spring wood grain, wherein at least one surface of the timber composite includes raised portions and depressed portions, wherein the raised portions correspond to the summer wood grain and the depressed portions correspond to the spring wood grain.

The invention relates to a bamboo floor, in particular to a composite bamboo floor. The composite bamboo floor comprises a floor surface board provided with a body, a pressed surface, a connecting surface connected with the core board, at least one cut surface board side face and surface board end faces, and the core board arranged under the floor surface board and provided with a core board surface connected with the floor surface board, a core board bottom surface, core board side faces and core board end faces, and the positions of the core board side faces or the core board side faces and the surface board side faces are provided with notch structures processed in two sides in the length direction of the composite bamboo floor. The composite bamboo floor is high in strength, high in processing efficiency and low in production cost.

A coating and its application methods to coat at least one surface of a substrate, in particular cellulose-based substrates, and give it barrier properties to water, grease, oxygen, lights, moisture; heat resistance, a lower friction coefficient. The coating does not change the original properties of flexibility, biodegradability and recyclability of the original substrate. The coated substrate can be printed, can be recycled and exhibits unchanged properties in areas requiring folding of paper or cardboard.

A method for repairing window laminates in which two plies have become separated to create a void, and wherein moisture may have entered through an edge of the window laminate and into the void. The method includes the steps of: placing the window laminate in a vacuum bag and inserting the vacuum bag containing the window laminate into an oven or autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove the moisture between the plies; removing the vacuum bag and window laminate from the oven, and removing the window from the vacuum bag; forcing a needle on a syringe through the edge of the window laminate in the area of the void; and injecting an adhesive in the syringe into the void to fill the void with the adhesive.

A method of producing a building panel, including: providing a core, applying a balancing layer having a first moisture content on a first surface of the core, the balancing layer comprising a sheet impregnated with a thermosetting binder, applying a surface layer having a second moisture content on a second surface of the core, the surface layer comprising a thermosetting binder, adjusting the first moisture content of the balancing layer such that the first moisture content of the balancing layer is higher than the second moisture content of the surface layer prior to curing, and curing the surface layer and the balancing layer by applying heat and pressure. Also, a semi-finished product adapted to be cured for forming a building panel.
