Embodiment Construction

[0037] figure 1 A layered product is shown, more precisely a thickness block 10 consisting of a stack of sheets 1, 2, 3 of fibrous material. figure 2 A layered product is shown, more precisely a thickness block 20 consisting of a stack of metal sheets 11 , 12 , 13 . The method which will now be described in its various variants makes possible a layered product which can be used as desired, for example, for cutting into a shape suitable for its application, such as a drill with a precision comparable to that obtained in metals. Hole 19 is shown.

[0038] The process to be described also leads to layered products having high thermomechanical strength, in other words products which retain good mechanical properties when subjected to high temperatures, including in the presence of severe impacts.

[0039] That is to say, the layered product can be used as a thickness block until it may exceed 200°C and reach 280°C, 370°C, 380°C, or even 400°C or higher, at least and preferably ...

Abstract

The invention relates to a method for producing a shim (10), including the steps of: selecting a binding material having a state transition temperature (Tg) of more than 200 DEG C; coating sheets (1, 2, 3) having a predetermined tear resistance force with the binding material; stacking the coated sheets on top of one another; and subjecting the resulting stack to pressure and temperature cycles that cross-link the binding material so as to achieve a high cohesive strength between the sheets that is still lower than said predetermined tear resistance strength, and so as to maintain the thickness of the shim at a constant ratio to the number of sheets, said predetermined tear resistance strength, and said cohesive strength as long as the temperature of the shim is lower than said state-transition temperature (Tg).

Description

[0001] This application was submitted on September 23, 2011, and the priority date was September 24, 2010 and September 30, 2010. The application number is 201180051487.0, and the name is "the method for obtaining high temperature resistant and adjustable thickness pads and the A divisional application of the invention patent application for "Cushion block". technical field [0002] The present invention relates to layered products. [0003] More precisely, according to a first aspect, the present invention relates to a layered product having a thickness adjustable by layer peeling, the product comprising an accumulation of sheets, each sheet having an inherent tear resistance, and attached to each other by connecting forces , the joining force is less than the tear strength of the sheets, so that each sheet can be separated from the stack without tearing. Background technique [0004] This product is described in the patent of invention FR2831095B1, and these products are ...
