Title:
STITCHED ELECTROMAGNETIC WAVE ABSORBING COMPOSITE MATERIAL FOR LOW-SPEED IMPACT PROTECTION
Document Type and Number:
WIPO Patent Application WO/2023/033246
Kind Code:
A1
Abstract:
The present invention relates to a stitched electromagnetic wave absorbing composite material for low-speed impact protection and, in particular, to a composite material that exhibits electromagnetic wave absorption performance and at the same time, low-speed impact protection performance by applying a stitching process, which is a thickness-direction reinforcement method, to a composite material that is an electromagnetic wave absorber. The present invention provides a stitched electromagnetic wave absorbing composite material for low-speed impact protection, the electromagnetic wave absorbing composite material comprising a composite material composed of at least one of glass fiber, epoxy, or glass fiber reinforced plastics (GFRP), wherein the composite material absorbs electromagnetic waves, and has been subjected to the application of an impact protection system through stitching.
