Strength between PEEK and PEEK-CF
PEEK offers good strength with a tensile strength of around 90-100 MPa, while PEEK-CF (carbon fiber reinforced) has significantly higher tensile strength (100-200 MPa) and flexural strength (150-250 MPa), providing greater stiffness and wear resistance. However, PEEK-CF may have slightly lower impact strength due to its brittleness from the carbon fiber reinforcement.
