These fibers contained about 85% carbon and had excellent flexural strength.
In this case, correctly modeling ice's downward flexural strength is most important.
The flexural strength represents the highest stress experienced within the material at its moment of rupture.
The flexural strength would be the same as the tensile strength if the material were homogeneous.
Therefore it is common for flexural strengths to be higher than tensile strengths for the same material.
But, the binding agents often continue to harden, leading to a loss of flexural strength over time.
Generally fibers do not increase the flexural strength of concrete, and so cannot replace moment-resisting or structural steel reinforcement.
Increasing the aspect ratio of the fiber usually segments the flexural strength and toughness of the matrix.
Tensile flexural strength is associated with the capacity of an anode to withstand a three point load.
Higher flexural strength results in a broadening of the gravity anomaly with time.
