Surface degradation assisted welding for vitrimer composites
Materials Letters(2022)
摘要
•Strong welding of vitrimer composites is anticipated but remains challenging.•Surface degradation is introduced to assist in welding epoxy vitrimer composites.•A high welding strength of ∼25 MPa is obtained.•The required pressure is two orders of magnitude smaller than that by direct welding.
