Composite material, production method for molded object, and production method for composite material |
| abstract |
The present invention provides: a composite material which comprises a thermoplastic matrix resin and carbon fibers A comprising carbon fiber bundles A1 in which Li/(Ni × Di<sup>2</sup>) satisfies 6.7 × 10<sup>1</sup>to 3.3 × 10<sup>3</sup>, wherein the carbon fibers A have a fiber length of 5-100 mm and have a value of Lw<sub>A1</sub>/(N<sub>A1</sub>ave × D<sub>A1</sub><sup>2</sup>) of 1.0 × 10<sup>2</sup>to 3.3 × 10<sup>3</sup>, the carbon fiber bundles A1 having an average bundle width W<sub>A1</sub>less than 3.5 mm and being contained in an amount of 90 vol% or larger with respect to the carbon fibers A; a production method for the composite material; and a method for producing a molded object from the composite material. Li is the fiber length (mm) of carbon fiber bundles. Di is the single-filament diameter (mm) of the carbon fibers constituting the carbon fiber bundles. Ni is the number of the single-filament fibers contained in the carbon fiber bundles. Lw<sub>A1</sub>is the weight-average fiber length (mm) of the carbon fiber bundles A1. N<sub>A1</sub>ave is the average number of single-filament fibers contained in the carbon fiber bundles A1. D<sub>A1</sub>is the single-filament diameter (mm) of carbon fibers constituting the carbon fiber bundles A1. |
