Li is the fiber length (mm) of the carbon fiber bundles. Di is the single-filament diameter (mm) of the carbon fibers constituting the carbon fiber bundles. Ni is the number of single-filament fibers contained in the carbon fiber bundles. Tf is [(basis weight of the carbon fiber mass)/(density of the carbon fibers)] × 3 (mm).
