“Larger Fiber Bundle Size Increases Flexural and Interlaminar Shear Strength in 3D Printed Carbon Fiber Composites”

https://pubmed.ncbi.nlm.nih.gov/38116214

The study found that a larger fiber bundle size in additively manufactured continuous carbon fiber reinforced thermoplastic composites can significantly improve flexural and interlaminar shear strength, but has minimal impact on tensile strength.
