Benefits of technology

[0018] The invention may provide a thermosetting resin composition in which carbon nanofibers are dispersed, and a method of producing the same.
[0041] This provides a thermosetting resin composition with a high rigidity similar to that of a metal structural material. Moreover, use of the epoxy resin enables the thermosetting resin composition to be molded into a desired shape at a low temperature in a short time in comparison with a metal material, whereby cost of the production process can be reduced. Moreover, a reduction in weight can be achieved.

Problems solved by technology

However, technology of uniformly dispersing the carbon nanofibers in a thermosetting resin has not yet been established.

[0112] Examples according to the invention and comparative examples are described below. Note that the invention is not limited to the following examples. (Examples 1 to 7 and Comparative Examples 1 to 3)

(1) Preparation of Sample

[0113] Step (c)

[0114] An epoxidized elastomer was supplied to a 6-inch open roll (roll temperature: 10 to 50° C.) and wound around the roll. An epoxy resin (base resin) was supplied to and mixed with the epoxidized elastomer to obtain a first mixture. The roll distance was set at 1 mm, and the roll rotational speed was set at 22 rpm / 20 rpm. The types and amounts (phr) of the epoxidized elastomer and the epoxy resin are shown in Tables 1 and 2.

[0115] Step (d)

[0116] A filler was supplied to and mixed with the first mixture. After reducing the roll distance to 0.1 mm, the mixture was tight-milled five times to obtain a second mixture. The roll rotational speed was set at 22 rpm / 20 rpm. After setting the roll distance at 1 mm and the roll rotational speed ...

Abstract

A thermosetting resin composition including: a matrix including a thermosetting resin and an elastomer; and carbon nanofibers dispersed in the matrix. The elastomer includes an unsaturated bond or a group having affinity to the carbon nanofibers.

Description

[0001] Japanese Patent Application No. 2005-327404, filed on Nov. 11, 2005, and Japanese Patent Application No. 2006-82871, filed on Mar. 24, 2006, are hereby incorporated by reference in their entirety. BACKGROUND OF THE INVENTION [0002] The present invention relates to a thermosetting resin composition and a method of producing the same. [0003] A composite material has been generally provided with physical properties corresponding to the application by combining a matrix material and reinforcing fibers or reinforcing particles. In particular, in the fields of semiconductor manufacturing instruments, optical instruments, microfabrication instruments, and the like, a reduction in the effects of the thermal expansion of parts has been demanded. Therefore, composite materials using various reinforcing fibers such as carbon fibers have been proposed (see WO00 / 64668, for example). [0004] The inventors of the invention have proposed a carbon fiber composite material in which carbon nanof...
