1. a kind of distal radial palmar lockplate, which is characterized in that including:

  • Locking plate body compatible with radius, the locking plate body includes the distal radius fixed part being connected with each other and branchPortion is provided with multiple first mounting holes, multiple kirschner pin holes and peep hole, in the branch cadre in the distal radius fixed partOn be provided with multiple second mounting holes, multiple interim fixing holes and pressurization hole, pressurization hole above be provided with graduation mark;

    The position of left end edge close to the radius of the distal radius fixed part is provided with raised item, the distal radius fixed partUpper position edge carry out ultrathin design;

    The locking plate body is prepared by PEEK composite materials, and the preparation method of the PEEK composite materials includes following stepSuddenly:

    Step 1:

    Broaden carbon fiber carbon filament;

    Step 2:

    PEEK aqueous liquid dispersions are prepared, the carbon filament after broadening described in step 1 is presoaked and dried in the dispersion liquidTo preimpregnation carbon filament;

    Step 3:

    Preimpregnation carbon filament described in milling step 2 obtains carbon fibre initial rinse unidirectional cloth;

    Step 4:

    Laying is carried out with the preimpregnation unidirectional cloth described in step 3;

    Step 5:

    Ply angles obtained by step 4 are put into mold and are molded, PEEK composite materials are obtained;

    It is characterized in that:

    In the step 1, carbon fiber carbon filament is stretched to 700-900 roots/millimeter;

    In the step 2, preparePEEK aqueous liquid dispersions surface tension in 20dyn/cm hereinafter, viscosity be 1800-2000CPS;

    In the step 3, rollingNumber be 1-3 times;

    In the step 4, when laying each layer be different angle staggeredly.
