摘要

Abstract

Glass-fiber-reinforced polymer composites (GFRCs) have a wide range of applications. However

under complex service conditions

GFRCs are prone to internal damage that is not readily detectable

thereby posing potential safety risks. In this study

camphoric acid diglycidyl ester (CADE) was synthesized from bio-based camphoric acid (CPA) and subsequently cured with 4

4′-diaminodiphenyl disulfide (APD) to construct a CADE-APD vitrimer featuring a dual dynamic network based on disulfide and

-hydroxy

ester bonds. After compositing with glass fibers

the resulting composite exhibited excellent mechanical performance

recyclability

UV shielding

and damage self-reporting capability. Benefiting from disulfide exchange and transesterification reactions

the vitrimer network demonstrates rapid stress relaxation

with a relaxation time of 50 s and an activation energy (

) of 74.66 kJ/mol. Notably

mechanical damage induces disulfide bond cleavage

generating thiyl radicals that result in a visible green color change

enabling real-time damage. The composites could be rapidly degraded in

-mercaptoethanol

via

thiol-disulfide exchange. Owing to the introduction of a rigid five-membered ring derived from camphoric acid

both the vitrimers and GFRCs exhibit excellent mechanical properties. This study provides a new approach for the preparation of multifunctional bio-based glass-fiber-reinforced polymer materials.
