Title:
POLYVINYL CHLORIDE-BASED CARBON FIBER REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/196153
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a CFRP using a vinyl chloride-based resin composition having excellent impregnation ability into a carbon fiber base material. This carbon fiber reinforced composite material comprises a vinyl chloride-based resin composition (A) and a carbon fiber base material (B). The vinyl chloride-based resin composition (A) contains a vinyl chloride-based resin and one or more additives. The vinyl chloride-based resin composition (A) and the carbon fiber base material (B) satisfy the following property (1) and property (2). Property (1): The complex viscosity η of the vinyl chloride-based resin composition (A) at 200°C at a frequency of 10 Hz satisfies 1 <η < 1500. Property (2): A value S calculated using a solubility index (Ra(pi)), a solubility index (Ra(ci)), and the weight fractions C(i) of the additives (i) present in the vinyl chloride-based resin composition (A) is 150 or less, where the solubility index (Ra(pi)) is calculated using the Hansen solubility parameters of the respective additives (i) present in the vinyl chloride-based resin composition (A) and the Hansen solubility parameters of the vinyl chloride-based resin (p) used, and the solubility index (Ra(ci)) is calculated using the Hansen solubility parameters of the respective additives (i) and the Hansen solubility parameters of the carbon fiber base material (B).
