12. Prediction of the Fibre-Reinforced Polymer Hull on the Wave Slamming Impact

This paper predicts the influence of the fibre-reinforced polymer (FRP) hull on the wave slamming impact. The hull comes in various materials, such as aluminium, steel, wood, and FRP. The material used in this research is the hull lamination of FRP because of several advantages, such as corrosion resistance, non-magnetic properties, lightweight, high tensile strength, and reduced impact. Note that the wave impact of slamming, which occurs in three cases: bottom slamming, bow-flare slamming, and stern slamming, causes fatigue damage on the hull surface, leading to the growth of fracture cracks in the hull. Therefore, the hull laminate method will be used in this research, which is a stacked sequence with a +45° layer orientation with different types of fibre mats (tissue mat, chopped strand mat, and woven roving). Thus, researchers used the laminated FRP hull in a real boat model simulation in the ANSYS software with the wave impact of the slamming on the hydrodynamic diffraction.

Implementation of simulation on the real model to address real impacts found that the maximum pressure of 14,689.9 MPa occurred at the middle of the hull on the first laminate layer. Apart from that, the study discovered reducing the wave impact of slamming on the hydrodynamic diffraction. The results are significant for the future study and the implementation of the real boat.
