Abstract:Understanding stress distribution in fiber‐reinforced polymers is critical to extending their operational lifespan. The integration of mechanoresponsive molecular force probes, referred to as mechanophores, presents a potential solution by enabling direct monitoring of stress concentration. In this study, spiropyran (SP) mechanophores (MPs) are embedded within a polydimethylsiloxane (PDMS) matrix to visualize stress localization during fracture within a single fiber‐reinforced framework. The SP mechanophore un… Show more
