Abstract
Articles are disclosed, and methods and apparatuses for making the same, the articles having two or more bonded layers, such as polymer layers. The two or more layers are bonded together by pressing the two or more layers between a first pressing surface and a second pressing surface to a pressure of at least 10,000 psi.
Claims20
A method of manufacturing an article, the method comprising:
- placing a compliant layer between a first pressing surface and a press;
- placing a first polymer layer in contact with a second layer;
- and
- pressing the first polymer layer and the second layer between the first pressing surface and a second pressing surface to a pressure of at least 10,000 psi, thereby forming a bond between the first polymer layer and the second layer.
1 more element
An article comprising:
- a first polymer layer comprising a surface and a porous microstructure, the porous microstructure comprising fractured fibrils;
- and
- a second layer comprising a surface adjacent to and bonded to the surface of the first polymer layer.
An article comprising:
- a first polymer layer comprising a first surface and a second surface, the first surface comprising a rough surface;
- and
- a second layer comprising a surface adjacent to and bonded to the second surface of the first polymer layer.
