multi-layer composite structure, use of a multi-layer composite structure, and laminated structure

摘要

COMPLIMENT LAYER STRUCTURE, USE OF A COMPLETE LAYER STRUCTURE, AND, LAMINATED STRUCTURE Composite laminates are described which may have high strength and / or low dielectric loss and may also be lightweight. The laminates include layers formed of high modulus polyolefin fiber. The fibers may be woven or knitted to form a cloth or may be included in a nonwoven cloth which may be one or more layers of the composite structures. Layers including high modulus polyolefin fibers may include other fibers, such as glass fibers. The composites may also include layers of other materials, for example layers formed of non-woven polyamide, glass fiber, or carbon fiber. The composites may be advantageously used in low loss dielectric applications, such as in the function of circuit board substrates, or in applications that beneficially combine resistance such as low weight, such as automotive and marine materials.
