AI Technical Summary

Technical Problem

Traditional underwater protective materials cannot simultaneously meet the dual requirements of dynamic stealth and high-efficiency impact resistance, and their energy supply is limited in the deep-sea environment, resulting in insufficient environmental adaptability in many situations.

Method used

The composite structure employs a photochromic stealth layer, an interface coupling layer, and a shear-toughened explosion-resistant layer. The photochromic stealth layer achieves dynamic color change through photosensitive liquid crystal microcapsules, the interface coupling layer achieves synergistic mechanical properties through a gradient composite structure, and the shear-toughened explosion-resistant layer achieves high-efficiency impact resistance through a biomimetic neural bundle network and a shear-thickening liquid.

Benefits of technology

It achieves excellent optical stealth performance, shock resistance and environmental adaptability in complex underwater environments, and has ultra-low light reflection, dynamic color-changing stealth, autonomous power supply and multi-field environmental stability, making it suitable for dynamic camouflage and shock protection of deep-sea equipment.

Abstract

This invention discloses a composite layer and its application, relating to the technical field of marine engineering protective materials. A composite layer includes, from top to bottom, a photochromic stealth layer, an interface coupling layer, and a toughened and blast-resistant layer. The photochromic stealth layer comprises a polymer matrix and photosensitive liquid crystal microcapsules embedded in the polymer matrix. The photosensitive liquid crystal microcapsules are filled with an azobenzene-based liquid crystal material, and a conductive layer is disposed on the surface of the photosensitive liquid crystal microcapsules. The interface coupling layer includes, from bottom to top, a flexible layer, a transition layer, and a rigid layer. The shear-toughened and blast-resistant layer comprises an epoxy resin matrix, a biomimetic neural bundle network embedded in the epoxy resin matrix, and a shear-thickening liquid. The composite layer of this invention possesses excellent optical stealth performance, impact resistance, and environmental adaptability, making it suitable for dynamic camouflage and impact protection of deep-sea equipment, underwater vehicles, and marine engineering structures.
