Numerical Modeling Method of GFRP Laminate with Flexural Interphase

摘要

The interphase has an important role which supports the stress transmission between fiber and resin. Authors introduced the concept of flexural interphase, established the fabrication machine of prepregs. In this study a new numerical model of considerd the fiber/resin interphase is proposed, in order to design the flexural interphase. Using the proposed model, the mechanical behaviors of unidirectional GFRP laminates with various flexural interphase thickness were simulated. Therefore the validity of the proposed model was confirmed. It was also concluded that the model was effective for the fiber/resin interphase designing in the GFRP composite structures.
