Omnidirectionally stretchable fiber-reinforced composite film and manufacturing method thereof

Abstract

The present invention provides a fiber-reinforced composite film with omnidirectional stretchability on which an auxetic structure 100 is formed integrally with the film on a film, wherein the auxetic structure 100 comprises a plurality of space regions 130 in the form of single closed curves regularly arranged on the film; an island 120 formed surrounded by the space region 130; and a connection portion 110 formed at regular intervals by the space region 130 to connect adjacent islands 120; wherein the film, island 120 and connection portion 110 are plastic materials reinforced with fibers wherein the space region 130 is filled with the elastic auxiliary member 20 and a manufacturing method thereof.
