RESIN COMPOSITE MATERIAL AND METHOD FOR MANUFACTURING RESIN COMPOSITE MATERIAL

摘要

Provided are a resin composite material containing plate-shaped exfoliated graphite or exfoliated graphite oxide with few folds and wrinkles and having effectively-enhanced mechanical strength such as tensile elastic modulus and a method for manufacturing the resin composite material. The resin composite material is a resin composite material including a synthetic resin and exfoliated graphite or exfoliated graphite oxide, wherein an average value of an average degree of flexion of the exfoliated graphite or of the exfoliated graphite oxide in one of two orthogonal cutting planes along which the resin composite material is cut and an average degree of flexion of the exfoliated graphite or of the exfoliated graphite oxide in the other cutting plane is less than 0.3. The method for manufacturing the resin composite material includes the steps of: preparing two or more resin compositions having the synthetic resin and the exfoliated graphite or the exfoliated graphite oxide; and stacking and pressing the resin compositions together after the preparation step.

1. A resin composite material comprising a synthetic resin and exfoliated graphite or exfoliated graphite oxide,
wherein when a value represented by (1-A/B), where A is a shortest distance between both ends of a cross-section of one of the exfoliated graphite or of the exfoliated graphite oxide exposed in one cutting plane along which the resin composite material is cut and B is a length of a path between the both ends, is defined as a degree of flexion of the one of the exfoliated graphite or of the exfoliated graphite oxide in the cutting plane and an average value of degrees of flexion of the exfoliated graphite or of the exfoliated graphite oxide exposed in the cutting plane is defined as an average degree of flexion in the cutting plane, an average value of an average degree of flexion of the exfoliated graphite or of the exfoliated graphite oxide in one of two orthogonal cutting planes along which the resin composite material is cut and an average degree of flexion of the exfoliated graphite or of the exfoliated graphite oxide in the other cutting plane is less than 0.3.
