Formed fiber product, fibrous binder, and application thereof

Abstract

One of problems to be solved is to provide a formed fiber product having sufficient strength and a composite material using the formed fiber product. Furthermore, another one of problems to be solved is to provide a formed fiber product having sufficient strength and a composite material using the formed fiber product, by use of carbon fiber. A formed fiber product that has been processed into nonwoven fabric or the like is manufactured by use of a fibrous binder that has been fibrillated. An embodiment of the formed fiber product includes a main fiber material and a fibrous binder and has a content ratio of 1 to 20 parts by weight of the fibrous binder to 100 parts by weight of the main fiber material, and the fibrous binder has a crill ratio ranging from 1.25 to 3.00.
