The Ultimate Tensile Strength of Carbon Fiber constant displays the value of ultimate tensile strength for carbon fiber (4000 MPa).
The strength of a material is its ability to withstand an applied load without failure or plastic deformation. The capacity of a material to withstand loads tending to elongate is known as ultimate tensile strength (UTS). The UTS for carbon fiber is 4000 MPa.
