Herein, we introduce a topology engineering strategy based on an imide\u2010containing dual\u2010role hyperbranched platform, which acts simultaneously as reactive tougheners and interfacial coupling agents. Within the matrix, the hyperbranched architecture interpenetrates the linear epoxy network, forming a distinctive dual\u2010phase \u201cpenetration\u2010locking\u201d topology that reduces free volume and increases effective cross\u2010link density. At the fiber\u2010matrix interface, thiol\u2010terminated hyperbranched molecules enable covalent interphase formation via thiol\u2010ene click chemistry, enhancing interfacial adhesion and stress transfer. This chemically integrated design enables cost\u2010effective T300\u2010based composites to reach a tensile strength of 740\u00a0MPa, comparable to conventional T800\u2010based composites, while T800\u2010based composites achieve up to 1.1\u00a0GPa. Importantly, the incorporation of imide and ester linkages introduces chemically addressable cleavage sites, enabling selective depolymerization under mild alkaline methanolysis, recovery of carbon fibers with retained integrity, and upcycling of oligomeric products as curing agents. This work establishes a molecular design framework that couples network topology, interfacial chemistry, and dynamic covalent functionality, providing a versatile platform for high\u2010performance thermoset composites with improved lifecycle sustainability.<\/jats:p>","DOI":"10.1002\/anie.3897515","type":"journal-article","created":{"date-parts":[[2026,10,19]],"date-time":"2026-10-19T13:02:42Z","timestamp":1792414962000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hyperbranched
