The purpose of this study is to develop a lightweight design model for an 18ft leisure boat. The existing leisure boat is manufactured using glass fiber-reinforced plastics (GFRP) material and the hand lay-up process. Carbon fiber-reinforced plastics (CFRP) was applied to the new design to reduce the boat’s weight, while an automated tape laying machine was applied to the lightweight boat’s manufacturing process to increase boat manufacturing productivity. The newly designed CFRP model is 25% lighter than the existing GFRP model. It was confirmed that the newly designed lightweight hull has sufficient structural integrity compared to the existing hull through the structural integrity evaluation by the FEA.

18英尺CFRP休闲船结构设计与分析研究

本研究的目的是为 18 英尺休闲船开发轻量化设计模型。现有的休闲船采用玻璃纤维增​​强塑料 (GFRP) 材料和手糊工艺制造。碳纤维增强塑料 (CFRP) 应用于新设计以减轻船的重量，而自动铺带机应用于轻型船的制造过程以提高船的制造效率。新设计的 CFRP 模型比现有的 GFRP 模型轻 25%。通过有限元分析机构的结构完整性评估，确认新设计的轻型船体与现有船体相比具有足够的结构完整性。
