Abstract:
A method of producing a finely fibrous cellulose composite prepreg sheet, sheet or laminate sheet, the method including a mixing an emulsion of a reactive compound with an aqueous suspension containing a finely fibrous cellulose to prepare a mixed liquid dewatering the mixed liquid by filtration on a porous substrate to form a water-containing sheet; and heating and drying the water-containing sheet. A method of producing a finely fibrous cellulose composite sheet, the method including subjecting the finely fibrous cellulose composite prepreg sheet produced by the method described above to a curing treatment.
