  • Patent number: 10287236
    Abstract: A method i for forming an epoxidized polymer is provided. The method may include mixing an epoxidized plant oil with a synthetic epoxy resin and crosslinking the epoxidized plant oil and the synthetic epoxy resin using a curing agent. The epoxidized plant oil may be formed via: converting plant oil triglycerides to fatty amide alcohols via aminolysis using primary or secondary amines, converting the fatty amide alcohols to epoxidized fatty amide alcohols, and reacting the epoxidized fatty amide alcohols with vinyl monomers to obtain epoxidized plant oil monomers.

  • Patent number: 10233926
    Abstract: The present invention recites a method of fabricating a stator for a downhole motor, the method comprising the steps of providing a stator tube having an interior surface and applying a bonding agent to the interior surface of the stator tube. Additionally, a mandrel is positioned within the stator tube, the mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator. Furthermore, a reinforcing material is introduced into the stator tube to fill space between the mandrel and the interior surface of the stator tube and subsequently solidified to bond the reinforcing material to the interior surface of the stator tube. The mandrel is then removed from the bonded stator tube and reinforcing material such that a stator is fabricated.
