Abstract
The present invention relates to anionically modified microfibrillated plant fibers used for obtaining a thermosetting resin molding material having excellent mechanical strength, a method for manufacturing the same, a molding material containing the anionically modified microfibrillated plant fibers and a thermosetting resin, and a method for manufacturing the same. Specifically, the present invention provides a molding material containing anionically modified microfibrillated plant fibers that are anionically modified in the presence of a base by a carboxylic acid represented by formula (I): X—(CH)—COOH (I), wherein X represents halogen and n is 1 or 2, and/or by a salt thereof, and a thermosetting resin, and the molding material contains the anionically modified microfibrillated plant fibers in an amount of 10 to 900 parts by weight per 100 parts by weight of the thermosetting resin.
