Structural design of graded roller pressing device for continuous forced assembly processing equipment of polymer composites

Abstract

Abstract:

Continuous roll⁃spatial confining forced network assembly （CR⁃SCFNA） innovatively reengineers the traditional flat⁃plate hot⁃pressing method into a dynamic “flexible roll⁃to⁃plate” process. By integrating the mechanical force of rollers with the intrinsic self⁃assembly behavior of fillers， CR⁃SCFNA synergistically drives the formation of a high⁃density filler network. The system employs a graded roller press that progressively compresses the composite material to align with the dimensional specifications of the limit plate. Experimental results demonstrated that applying forced assembly forces， specifically radial compression combined with orthogonal shear forces， enabled precise alignment and directional organization of fillers within the polymer matrix. This created a densely interconnected thermally/electrically conductive network. This breakthrough process significantly enhances the thermal and electrical conductivity of polymer composites， addressing the growing industrial demand for lightweight， high⁃performance materials in applications such as electronics， energy systems， and advanced manufacturing.
