COMPOSITE RESIN MOLDED ARTICLE AND METHOD FOR PRODUCING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240018343 titled 'COMPOSITE RESIN MOLDED ARTICLE AND METHOD FOR PRODUCING SAME

Simplified Explanation

The abstract describes a patent application for a composite resin molded article that contains a base resin and a plurality of natural fibers dispersed in the base resin. The content of the natural fibers in the composite resin molded article ranges from 10% to 99% of the total mass. At least one of the natural fibers has a defibrated site at one end, and a portion of the fiber is exposed on the surface of the molded article. The base resin is a biodegradable plastic, such as a polyhydroxy acid, polyhydroxyalkanoate, polyalkylene dicarboxylate, or modified starch.

  • The patent application is for a composite resin molded article that incorporates natural fibers into a base resin.
  • The natural fibers make up a significant portion of the molded article, ranging from 10% to 99% of the total mass.
  • At least one of the natural fibers has a defibrated site at one end, which enhances the bonding between the fiber and the resin.
  • A portion of the natural fiber is exposed on the surface of the molded article, providing a natural and textured appearance.
  • The base resin used in the molded article is a biodegradable plastic, which is environmentally friendly.
  • The base resin can be made from various biodegradable materials, such as polyhydroxy acids, polyhydroxyalkanoates, polyalkylene dicarboxylates, or modified starch.

Potential applications of this technology:

  • Packaging materials: The composite resin molded article can be used to create biodegradable packaging materials, reducing the environmental impact of single-use plastics.
  • Consumer products: The natural and textured appearance of the molded article makes it suitable for various consumer products, such as phone cases, kitchenware, or decorative items.
  • Automotive industry: The composite resin molded article can be used in the production of interior components, providing a sustainable alternative to traditional plastics.

Problems solved by this technology:

  • Environmental impact: The use of biodegradable plastics and natural fibers reduces the environmental impact of plastic waste.
  • Enhanced bonding: The defibrated sites on the natural fibers improve the bonding between the fibers and the resin, increasing the strength and durability of the molded article.
  • Aesthetics: The exposed natural fibers on the surface of the molded article provide a unique and textured appearance, enhancing the visual appeal of the product.

Benefits of this technology:

  • Sustainability: The use of biodegradable plastics and natural fibers promotes sustainability and reduces reliance on non-renewable resources.
  • Improved strength and durability: The enhanced bonding between the fibers and the resin improves the strength and durability of the molded article.
  • Aesthetic appeal: The exposed natural fibers on the surface of the molded article provide a natural and textured appearance, adding aesthetic value to the product.


Original Abstract Submitted

a composite resin molded article contains: a base resin; and a plurality of natural fibers dispersed in the base resin, in which a content of the plurality of natural fibers in the composite resin molded article is from 10 mass % to 99 mass % inclusive, based on 100 mass % of the composite resin molded article, at least one of the plurality of natural fibers has a defibrated site at an end portion in a fiber length direction of the at least one of the plurality of natural fibers, the at least one of the plurality of natural fibers has a portion exposed on a surface of the composite resin molded article, and the base resin is a biodegradable plastic containing any one selected from the group consisting of a polyhydroxy acid, a polyhydroxyalkanoate, a polyalkylene dicarboxylate, and a modified starch.
