Interlayer refers to a material or component that is placed between two main layers or surfaces in order to provide insulation, separation, or reinforcement. It acts as a middle layer that enhances the overall performance, integrity, or functionality of the structure or system it is incorporated into.
In construction, an interlayer can be used to prevent the direct contact between two different materials or surfaces. For instance, in insulated glass windows, an interlayer such as polyvinyl butyral (PVB) is placed between the glass layers to enhance thermal insulation, soundproofing, and safety by holding the glass fragments together if shattered.
In the field of composites, an interlayer is often employed to improve the bonding between different layers and add structural strength. It may be made of fiberglass, Kevlar, or carbon fiber, providing reinforcement and enhancing the overall rigidity, impact resistance, and durability of the composite structure.
Moreover, interlayers can be found in various industries, such as automotive, aerospace, and electronics. They can serve as a barrier against moisture, gases, or chemicals, preventing their penetration or leakage. Additionally, interlayers can possess special properties like fire resistance, UV protection, or electrical insulation, making them useful in specific applications.
Overall, the term interlayer encompasses the concept of an intermediary element that plays a crucial role in improving, connecting, or protecting the layers or surfaces it is situated between, thereby enhancing the overall performance and functionality of the system.
