The present study concerns with the experimental and analytical investigation of long fibre thermoplastic composite beam subjected to impact loading. Nylon 6 beam specimens are used in this report. The specimens were subjected to a low velocity impact, drop weight test rig and a number of empirical relations and observations were obtained which relate the deformation of a specimen to the impact energy, percentage glass reinforcement (20%, 40%, 50%) and temperature (23oC). Three different glass fiber reinforcements have been tested and compared with the additional finite element results. A three-dimensional (3D) finite element analysis (ABAQUS/Explicit) has been employed to determine the deformation and failure of Nylon 6. A good agreement between finite element results and experimental findings was found.
