Introduction Despite having high tensile strength, most fiber-reinforced polymer (FRP) materials suffer from relatively low modulus of elasticity compared with steel.
The specific parameters are shown in Fig. 1, a variety of mechanical properties of materials measured as listed in Table 1 and Table 2.

Composite materials are used in aerospace structures due to their considerable bending stiffness and strength-to-weight ratio.
This is less than the compressive strength of the material (697 MPa).
