Abstract The mechanics of retraction of polymeric fibers imbedded in a polymeric matrix was analyzed. The shape evolution was described using a one-dimensional equation of equilibrium representing a balance between interfacial tension and viscous resistance. Microscopic tracking of polystyrene fibers in poly(methyl methacrylate) matrix was performed and compared with the data for the reverse material combination. The analysis of hydrodynamic and viscous factors was conducted using experimental results. It was found that the model provides an adequate description for the micromechanics of imbedded fibers. A characteristic time scale for the retraction was obtained.
