With a total of 7 patents to his name, Morioka's work has advanced the understanding and application of fiber-reinforced materials.
Latest Patents
Morioka's latest patents include a fiber-reinforced polyamide resin composition molded article. This innovative article is characterized by 5 to 50 parts by weight of reinforcing fibers, 40 to 94.9 parts by weight of a polyamide resin composition, and 0.1 to 10 parts by weight of an ammonium salt composed of ammonia and an aliphatic dicarboxylic acid having 6 to 12 carbon atoms. Additionally, the article features a weight average fiber length of the reinforcing fibers ranging from 0.4 to 7 mm. The polyamide resin composition comprises a polyamide resin, a second resin with a reactive functional group, and a compound produced by the reaction of the resin and the second resin, with the second resin dispersed in a form of particles with a number average particle diameter of 10 to 1,000 nm.
Another notable patent involves a method of producing polyamide fine particles. This method polymerizes a polyamide monomer in the presence of a polymer at a temperature equal to or higher than the crystallization temperature of the polyamide. The resulting polyamide fine particles have a number average particle size of 0.1 to 100 µm, a sphericity of 90 or more, and a crystallization temperature of 150°C or more.
