Method of Designing and Producing Carbon Fiber Push Rods

Abstract

A method of designing and producing a push rod uses continuous or discontinuous or chopped fiber pre-impregnated composite material wrapped around or surrounding a titanium tube, wherein the method allows push rod designers to machine several different push rod designs, lengths, diameters, and end types. The push rod would be shaped in a basic form (a blank having suitable length and stiffness), and then machined into a push rod. After the specific machining is performed, the oil drain hole is substituted with a titanium tube and the ends are capped with a suitable end for bearing against the rocker or the lifter, we then finish machining all surfaces. Push rods are then impregnated with Sodium Silicate to arrest fluid uptake.

1 . A method of designing and producing fully plated, titanium insulated composite push rods using a carbon based composite material, comprising the steps of:
 choosing one or a plurality of push rod designs;   overlaying said push rod designs to determine a single push rod blank design;   creating a reverse mold of said push rod blank design;   compression molding a push rod blank using said reverse mold; and   machining said push rod blank into one of said push rod designs.   
     
     
         2 . The method of  claim 1 , wherein choosing said push rod designs further comprises one or more of the steps of:
 determining diameter, length, end type and oil drain hole if necessary of said push rod designs prior to overlaying said push rod designs.   
     
     
         3 . The method of  claim 1 , wherein compression molding said push rod blank further comprises the steps of:
 heating composite material;   communicating said composite material after heating into said mold;   compressing said material in said mold using a press;   preferably applying sodium silicate impregnation; and   removing said material after cooling.
