Embodiment Construction

[0032] Providing adhesion of interlayers or adhesive layers or release layers on organic composite polymers is a current technical challenge. Many polymer composites include an organic matrix that requires protection during subsequent coating processes. "Protect" as used herein in the context of organic composites includes, without limitation, the reduction or elimination of chemical or physical changes to the composite matrix (organic and / or inorganic components) during or after one or more coating processes . Additionally, many of these polymers do not readily accept coatings due to differences in the chemical composition of the composite matrix and the material being coated. Therefore, there is a need for organic composite polymers that robustly and readily accept additional coatings to provide interlayers, adhesive layers or release layers to enable the organic composite to be used in more demanding applications.

[0033] Such polymer composites may include engineering r...

Abstract

An interlayer configured for a composite substrate surface, the interlayer having a higher concentration of at least one first chemical element at the interface of the substrate surface and the innermost interlayer surface and a higher concentration of at least one second chemical element at the outermost interlayer surface is disclosed. Methods of forming the interlayer and providing functional properties to said composites are disclosed.

Description

[0001] This application is a divisional application, the filing date of the original application is November 18, 2013, the application number is 201310581232.6, and the invention title is "Sandwich Composite Material Substrate". technical field [0002] The present disclosure relates to an interlayer configured for a composite substrate surface having a relatively high concentration of at least one first chemical element at the interface of the substrate surface and the innermost interlayer surface and a relatively high concentration at the outermost interlayer surface. A high concentration of at least one second chemical element. Methods of forming interlayers and imparting functional properties to the composite materials are disclosed. Background technique [0003] Despite their high strength, carbon-carbon composites, such as carbon fiber-reinforced polymers (CFRP), suffer from low wear resistance, thermal conductivity, and electrical conductivity, which limit their use i...
