The Structure and Flexural Properties of Typha Leaves

Figure 4

Flexural properties. (a) Typical force-displacement curves of the Typha leaf in the three-point bending test, where the numbers 1–6 are the six positions from the base to the apex, respectively. The variations in (b) flexural strength, (c) flexural modulus, and (d) elongation at break of three Typha leaves from the base to the apex.
