Abstract:
This study presents the option of an effective low-impact energy dissipating material applied to GFRP (glass fiber reinforced plastic) composite laminates using auxectic technology in the case of planing hull vessels that use the same high-speed light materials that repeatedly impact the surface of the water when sailing, producing a slamming phenomenon. Research shows that the option to modify the laminate with an auxectic layer protects the laminate from damage. This work proposes the manufacturing of dissipative layers, introduced in laminates made with a polymeric matrix and fiberglass reinforcement, which are evaluated with weight drop tests under different impact energies. The data are collected and processed by a unidirectional gravitometer that gives the acceleration values of the impactor. The tests compare unmodified panels with modified panels, showing that the energy absorbed by the unmodified panel is greater at equal energy levels. The returned energy comparison curve is shown, and the benefits of its use are presented.
摘要:
这项研究提出了一种有效的低冲击能量耗散材料的选择,该材料应用于GFRP(玻璃纤维增强塑料)复合材料层压板,在使用相同的高速轻型材料反复撞击水面的情况下,使用辅助技术航行时,产生撞击现象。研究表明,用辅助层修改层压板的选择保护层压板免受损坏。这项工作提出了耗散层的制造,引入由聚合物基体和玻璃纤维增强材料制成的层压板中,在不同的冲击能量下通过重量下降试验进行评估。数据由给出冲击器加速度值的单向重力计收集和处理。测试比较了未经修改的面板与经修改的面板,表明未经修改的面板在相同的能量水平下吸收的能量更大。返回的能量比较曲线如图所示,并介绍了其使用的好处。
