20090123726 | FIBER-REINFORCED COMPOSITE MATERIAL, METHOD FOR MANUFACTURING THE SAME, AND APPLICATIONS THEREOF - The present invention relates to a fiber-reinforced composite material and a method for manufacturing the same, and also relates to a transparent multilayered sheet, a circuit board, and an optical waveguide. | 05-14-2009 |
20090308552 | MICROFIBRILLATED CELLULOSE HAVING CELLULOSE TYPE-II CRYSTALLINE STRUCTURE, AND MOLDED ARTICLE CONTAINING THE MICROFIBRILLATED CELLULOSE - Although a microfibrillated cellulose has been conventionally added to a resin molded article for the purpose of improving the properties of resin such as strength, it is only possible to achieve the same level of strength as that of the resin itself. The object is to provide a resin molded article of greater strength. A molded article can be produced by blending resin with a microfibrillated cellulose having a type-II crystalline structure produced by treating a microfibrillated cellulose with an alkali solution. The molded article can be largely increased in tensile strength or flexural strength, tensile strain at break or flexural strain at break, and fracture toughness (work-of-fracture) compared to a molded article produced with resin containing a conventional microfibrillated cellulose. | 12-17-2009 |
20110319528 | METHOD FOR PRODUCING CHITIN NANOFIBERS, COMPOSITE MATERIAL AND COATING COMPOSITION EACH CONTAINING CHITIN NANOFIBERS, AND METHOD FOR PRODUCING CHITOSAN NANOFIBERS, COMPOSITE MATERIAL AND COATING COMPOSITION EACH CONTAINING CHITOSAN NANOFIBERS - The present invention provides a method for producing chitin nanofibers, which includes the steps of deproteinizing a material derived from a chitin-containing organism by an alkali treatment, deashing a deproteinized integument by an acid treatment, optionally treating the deashed integument under acidic conditions, and then subjecting to a fiber-loosening treatment. The present invention also provides chitin nanofibers obtained by the method, and a composite material and a coating composition each containing the same. The present invention provides a method for producing chitosan nanofibers, which includes, in addition to the above steps, a deacetylation step and chitosan nanofibers obtained by the method, and a composite material and a coating composition each containing the same. | 12-29-2011 |
