Method for the pre-estimation of extruding pressure and extruding velocity in the extrusion molding of particle-reinforced composites

摘要

The extrusion moldability of particle-reinforced composites under fresh cition relative to the extruding pressure and extruding velocity can be pre-estimated from the cohesion and the coefficient of internal friction of the composite which can be calculated from the relationship of, when a frame divided into the upper and lower halves are filled with the composite and the upper and lower halves of the frame are displaced relative to each other in the horizontal direction under a pressure on the composite filling the frame, the shear stress of the composite against slip deformation.
