| 摘要 |
A process for the deformation of a workpiece (7) of an orientable brittle polymer for example one reinforced with a ceramic powder (the composite), by passage in the solid phase through a die (6) having both an entry side and an exit side, which process includes providing the workpiece (7) of the composite having the orientable polymer phase at the entry side of the die, causing the workpiece (7) to deform in the solid phase through the die (6); and collecting the deformed workpiece (7) from the exit side of the die. The invention thus provides a process which can alter the stiffness or strength or ductile properties of a brittle material with a view to providing suitable orthopaedic implants. |
