So, when old bridge strengthened design is in consideration, in one hand, technical measures should be taken to minimize the damage to the structure of old bridge as far as possible, and influencing of the said damage should be assessed to ensure the old bridge strengthening plan is in the range of being condonable and operable in order to guarantee safety; in the other hand, something such as the influencing structure damage, poor quality construction materials, binding ability of old and new materials, difference of characteristic of materials must taken into consideration of old bridge strengthening plan.
materials bond to old bridge strengthened method should be adopted.
(2) Materials for old bridge strengthening Fiber composite materials belongs to new materials, at present, fiber composite materials used in old bridge strengthening includes carbon fiber, kevlar fiber and glass-fiber composite.
In view of performance of materials, carbon fiber is made from polyacrylonitrile or mesophase pitch in high temperature, which stress-strain are totally linear elastic without any yield point and plastic zone.

Equal Channel Angular Extrusion processes have implicitly exploited the internal shearing of materials to absorb impact energy [5].
Fig. 1b shows the idealised form of the shearing action that characterises the deformation pattern of deformable materials.
Plasticine is known to almost have a constant yield strength and could be used to simulate rigid-perfectly plastic materials.

In this research, investigation into material properties of the newly developed EC-PCD is made.
Recent years, application area of the PCD has been expanded to a grinding wheel for fine processing of hard to machine materials and a wear-less electrode for EDM.
And the material properties of the developed EC-PCD were examined.
