In order to improve the surface energy of PP, researchers have done their best in many modifications[1-6].
Standard curve was decided by a series of cardanol standard solution at 273 nm and 90 °C after dissolved in 1-octane.
Scheme 1 Chemical structure of cardanol Results and Discussion Effect of Initiator on Grafting Ratio The effect of initiator type on grafting ratio was investigated in order to select the optimum initiator (Table 1).

The length of the straight section① is Lc ,the curvature radius of ② and ④is R, the corner is β, the length of straight section ③ is L, the total length of the fiber is Lf, the specific values is showed ​​in Tab.1.
Table.1 The specific size of the selected hooked-end steel fibers parameters r Lc R L Β Lf values 0.45mm 1.83mm 2.23mm 1.36mm 0.66 60mm The elastic modulus of the steel fiber is 2.0 × 105MPa, Poisson's ratio is 0.3, tensile strength, 1450MPa,steel fiber is considered ideal plastic.
In order to meet the requirements of the model , the sharp of the section should be changed to the rectangular by equivalent change in area and moment of inertia of area, the length and width of a rectangular cross section to meet the requirements can be obtained by following two equations : ( 1 ) ( 2 ) Fig.1 The shape and size of hooked-end steel fibers Fig. 2 Mesh for the pull-out model of hooked-end steel fiber The ratio of the rectangular cross-section can be calculated by Formula(1) and (2).
Table.2 Two peak loads and the corresponding pull-out displacement load diaplacement The first peak load 479.9N 1.440mm The secondpeak load 314.9N 4.628mm It is showed by Fig.3 that the pull-out process of hooked- end fiber can be divided into the following phases: (1) before the end of the fiber is pulled , the relationship of load and displacement is linear , with the increase of load, the end of the fiber is pulled out, the nonlinear relationship between load and displacement occur, the first peak load appear when the pull-out displacement δ= 0.144mm, yet the end of the fiber of hook is near but do not pass the first corner, (2) after the peak , the end of the fiber begin to pass the first corner and the load began to decline, (3) When the displacement δ= 3.816mm, end of fiber entirely pass the first turn into the straight section ③ and the load began to rise with increase of displacement ,(4) When the displacement δ= 4.628mm, the end of fiber has not yet reached the second
