ABSTRACT
The present work describes a numerical investigation of the damage in a laminated composite material subjected to impact load. The study conducts on polyetheretherketone (PEEK) base laminated composite material reinforced by two types of fibers (glass and Kevlar) in order to studying the number of factors that may affect on the absorbed energy behavior of the composite material such as fibers, and velocity of impactor. The investigation was done by using finite element analysis software ANSYS 14. Results indicated that peak force in general increase when increase the velocity of impactor and the carbon reinforcing composite showed better resistance, on other hand the energy peaks also increase with increasing velocity.
Key words: numerical modeling, laminated composite, impact load, drop weight, ANSYS.
