Device and method for processing a fibre compound structure

In a method for processing a fiber compound structure, an unhardened fiber layer is arranged on a surface section of the fiber compound structure. A pressure cushion is arranged above the surface section. The pressure cushion has a pressure cap and a pressure-tight cap mat pressure-tightly connected to a circumferential border of the pressure cap such that the cap mat limits a pressure area together with the pressure cap. An overpressure in the pressure area is generated. The pressure cushion is pressed onto the fiber compound structure such that the overpressure presses the cap mat against the fiber layer while supporting the fiber compound structure on a side of the fiber compound structure that is opposed to the surface section. The fiber layer is hardened

A method for preparing a PBAT laminated membrane composite material uses PBAT or a material with PBAT as the main component and other biodegradable plastic or superfine calcium carbonate in a mixture. The temperature of the mixture is increased by means of a lamination machine segment by segment, the material is heated slowly to a molten state, and the temperature of a rolling shaft is controlled by introducing cold water to the rolling shaft when the lamination machine conducts membrane lamination, so that the temperatures of rolling wheels and the laminated membrane are controlled.

Device and method for extrusion of a solid body

The extrusion device of a solid film comprises a cell provided with an input opening of a material designed to form the solid film, and an output opening of the solid film from the cell. The device comprises a first heat exchanger for applying a first temperature to the output opening and a second heat exchanger for applying a second temperature in a first zone of the cell distinct from the output opening and a control circuit imposing first and second sets of first and second temperatures. The first set enables a volume of the material in solid phase to be formed. The second set enables a temperature gradient to be generated in the volume so as to generate a pressure forcing extrusion of the solid film via the output opening.

The invention relates to a method and arrangement of crosslinking or vulcanizing an elongate element, the method including an extrusion step in which a conductor element is coated by a layer of crosslinkable synthetic material and a crosslinking step in which crosslinking reaction is carried out after the extrusion step. The crosslinking reaction is carried out at first in a first heating zone by heating by heating the coated conductor element in a temperature of 550 degrees Celsius or higher. The first heating zone is located downstream of the extrusion step. After the first heating zone the crosslinking reaction is carried further by heating the coated conductor in a temperature of 200-300 degrees Celsius in a second heating zone.

FRICTION MATERIAL AND METHOD FOR MANUFACTURING THE SAME

Using a friction material composition comprising: a fiber; a friction adjusting material; a binding material; and an uncrosslinked rubber being solid at normal temperature (25 C.), a friction material is obtained, wherein an ambient compressibility in a piston-pressing direction is 2% or less at normal temperature (25 C.) and at 4 MPa, and a tan value in a sliding direction at 20 C. to 50 C. is 0.05 or larger. Thereby, a friction material which has high damping properties and acceptable brake noise, which can prevent a decrease in responsiveness when brakes are applied, and prevent a decrease in the feeling of effectiveness associated therewith, and which can suppress a decrease in the fuel efficiency and an increase in abrasion caused by the dragging occurring when the friction material is brought into contact with a brake rotor; and a method for producing the friction material, can be provided.
