▎ 摘  要

NOVELTY - Composite structure (300) comprises (i) a polymer layer (302); and an auxetic material layer arranged within the polymer layer, where the auxetic material layer provides increased conductivity and elastomeric reinforcement to the polymer layer or (ii) a polymer layer; a first portion of an auxetic material layer embedded within the polymer layer, where the first portion of the auxetic material layer provides increased conductivity and elastomeric reinforcement to the polymer layer; and a second portion of the layer positioned external the polymer layer. USE - The composite structure is used in electromagnetic shielding applications for use in airplanes or homes and microwave absorption applications. ADVANTAGE - The composite structure adopts the auxetic material layer that provides increased conductivity and elastomeric reinforcement to the polymer layer, shows that the use of auxetic fabric reinforcement offers a novel method of tailoring the composite's properties, can provide benefits of increased yield strength as well as maintaining much of the elasticity imparted from the polymer matrix, can be formed to exhibit both electromagnetic properties and elastomeric reinforcement without requiring significant processing and costs and can be sized to operate in various electromagnetic regions, such as the microwave region, without requiring significant changes in processing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for forming a reinforced composite structure, involving providing the polymer layer, and forming the auxetic material layer within or partially within the polymer layer, where the auxetic material layer comprising an auxetic material being coated with one or more conductive materials. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the composite structure having auxetic materials partially embedded in a polymer.
