https://www.wired.com/.../a-self-healing-pole-vault-pole.../ This is something I investigated in 2018 with a few of my friends at Bell Helicopter in Hurst Texas. Before a pole company wastes its research resources. One must first understand what causes a pole to break before looking at mending only the resins in the pole and not the fibers. Bike frames, rackets, golf shafts, flag poles, etc., are not bent more than a few degrees, as is a vaulting pole flexed over 90 degrees. Bicycle frames might get nicks on the surface and could be amended with a procedure such as the one suggested in the article. However, vaulting poles fail due to structural failures of the inner fabric, and one must understand that repairing or heating the surface to 110 degrees, as tested in a lab in 2018, cannot mend the structural failure of a pole. Adding resin to a vaulting pole will increase the weight of the pole and will show only areas of the pole that have just the resin scratched but not the fabric. Deep fabric scratches are going to fail. Rackets and bike frames use lots of carbon in a weave. One pole company in 2019 tried to use a carbon weave in their poles and ended up with a tremendous amount of pole breakage in the field. The thought of setting your poles in a long tube at meets overnight is an interesting myth. Pole resin is cured at 250 degrees. and a tube at what they were suggesting was 110 degrees. In Texas, where I live, you could lay your pole out in the sun for a meet, and it will reach a temperature of over 110 degrees; the properties of the pole will not change; only the pre-bend may be more pronounced. What is more important here is that poles break for many reasons beyond the manufacturer's reach after the sale. The athlete is responsible for the protection of their poles! And to buy from a company that understand why poles break and have the most durable pole. By prioritizing maintenance and being knowledgeable about their equipment, athletes can significantly extend the lifespan of their poles and enhance their performance.
