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

本研究提出了一种有效的低冲击能量耗散材料的应用方案，该材料采用复相转变技术应用于玻璃纤维增强塑料（GFRP）复合层压板，适用于滑行船体船舶。这类船舶使用相同的高速轻质材料，航行时会反复冲击水面，产生砰击现象。研究表明，用复相转变层对层压板进行改性的方案可保护层压板免受损坏。这项工作提出制造耗散层，将其引入由聚合物基体和玻璃纤维增强材料制成的层压板中，并在不同冲击能量下通过落重试验对其进行评估。数据由单向重力仪收集和处理，该重力仪可给出冲击器的加速度值。试验将未改性面板与改性面板进行比较，结果表明在相同能量水平下，未改性面板吸收的能量更大。给出了返回能量比较曲线，并展示了其使用的好处。
