DIY vacuum pump system which removes air pressure to 28 inches Hg. (Mercury) vacuum relative to 14.7 psi - sea level atmospheric pressure.
Sealed parts set in an epoxy resin are cured with this vacuum system while temperature and vacuum level is controlled. After about 24 hours, a lightweight molded part is produced. Parts, such as wings, are made from a composite structure and molded into a strong component using fabric materials, such as, fiberglass, carbon fiber, and kevlar. The point of this system is to produce a part with high material content and less than 40 % epoxy for maximum strength to weight.
Tank: 0.9 cu.ft. - about 7 U.S. gallons.
