Latest Patents
Okamoto's most recent patents include innovations in methods for preparing fiber/resin composites. His patents detail resin compositions that are particularly useful for filament winding applications. These compositions comprise a heat-curable polyepoxide resin and an olefinically unsaturated monomer component that can be cured using actinic radiation. Furthermore, his formulations contain photoinitiators, organic peroxides, and heat-activated curing agents designed for epoxides. Notably, the compositions achieve a viscosity of less than 2000 centipoise (cps) and maintain this consistency for at least 2 hours at temperatures ranging from ambient to 60 degrees Celsius. This innovative approach allows the resins to be immobilized through actinic radiation exposure and subsequently heat-cured without experiencing substantial drip. The patents further describe fiber resin composites comprised of fiber substrates impregnated with these dual-curing resin compositions, along with detailed processes for coating fiber substrates effectively.
