Abstract
Dynamic interphase-loading apparatus (DILA) has been developed to directly characterize the fiber/matrix interphase properties of composites under high loading rates. This apparatus uses a micro-mechanical method (micro-indentation) that is based on the debonding of a fiber from the matrix at the interphase region. Displacement rates up to 3000
μm/s that cause deformation of the interphase under high shear strain rates were obtained using the fast expansion capability of piezoelectric actuators (PZT). Transient force and fiber displacement for a specific displacement rate is measured during the test. The data are reduced to apparent average interphase shear strength and energy absorbed during debonding and frictional sliding during the micro-debonding process. An E-glass-fiber/epoxy-amine interphase was tested under various loading rates to demonstrate the capability of the test apparatus. Test results showed that the strength and energy-absorbing capability of the E-glass/epoxy-amine interphase are sensitive to loading rate.
