The Effect of Frequency and Strain Amplitude on the Fatigue Damage of Boron/Epoxy Fiber-Reinforced Composite Materials.

Abstract

The results of strain-controlled axial fatigue tests on boron/epoxy fiber reinforced composite materials are presented in the first of a series of reports detailing such results for a large number of fatigue tests run on boron/epoxy and boron/aluminum. The report contains a complete discussion of present experimental methods used in conjunction with this research program. Data from a series of undamaged (virgin) cyclic stress/strain tests at various frequencies, a series of strain controlled fatigue tests at 30Hz cyclic loading at several strain amplitudes and a series of constant strain amplitude fatigue tests at various frequencies (including all specimen and testing specifications) is presented and discussed at length. The effect of cyclic frequency on fatigue damage development is discussed and other pertinent trends are indicated.
