  • Publication number: 20190276670
    Abstract: A composite material is provided that includes a polymer matrix and fiber reinforcements within the polymer matrix, the fiber reinforcements including natural fibers having nanoparticles accumulated within a structure of the natural fibers. A method of forming the composite material is also provided that includes accumulating nanoparticles into the structure of the natural fibers to create accumulated natural fibers, drying the accumulated natural fibers, and mixing the accumulated natural fibers within the polymer matrix.

  • Patent number: 10344114
    Abstract: An additive manufacturing method. The method includes mixing a reflective material including fibers with a photopolymer resin to form a resin mixture having a loading of the reflective material of at least 3 wt. %. The method further includes curing the resin mixture using a light source to form first and second individually cured layers and a bridge of a portion of the fibers between the two layers.
    Type: Grant

  • Patent number: 9920154
    Abstract: Articles, methods of making an article, and resin compositions are disclosed. An article is disclosed that includes a cured light-curable resin having dispersed therein a reflective material that reflects at least 85% of the visible light spectrum. A loading of reflective material may be at least 3 wt. % of the article and the reflective material may comprise over 50 vol. % of a total filler composition of the article. The reflective material may be a white or near-white material, such as cellulose fibers, talc powder, or soy flour. A method is disclosed that includes mixing a reflective material that reflects at least 85% of the visible light spectrum with a photopolymer resin at a loading of at least 3 wt. % to form a resin mixture and curing the resin mixture using a light source in an additive manufacturing process. The disclosed resins may reduce the curing time of additive manufacturing processes.
