Lightweight fuel tank to be used as next generation transport equipment is required long time durability and high intensity. When discharged from liquefied gas tank of liquefied gas, damage occurred to tanks material by cavitation. This study is intended to damage process of the tanks material caused by cavitation in tank. Glass fiber reinforced plastic (GFRP) are considered as the tanks materials. R-134a used as pressure-liquefied gas at 273 K was boiled by instantaneous depressurization. Specimens of GFRP were immersed in the cyclic condition. Laser microscope measurements for the surface of GFRP specimens reveal complex change in the depth of vacancies with cyclic cavitation condition. Interlaminar shear strength of each GFRP specimen obtained from short beam three point bending tests in accordance with JIS K 7057:2006 is also affected by the cyclic condition.

作为下一代运输设备的轻质燃料箱，对其耐久性和强度要求较高。液化气从液化气储罐中排出时，储罐材料会因气蚀而损坏。本研究旨在研究储罐内空化对储罐材料的损伤过程。采用玻璃纤维增强塑料(GFRP)作为储罐材料。将R-134a作为加压液化气，在273K下进行瞬时降压沸腾。将玻璃钢试件浸泡在循环条件下。激光显微镜对玻璃钢试件表面的测量揭示了循环空化条件下空位深度的复杂变化。根据JIS K 7057：2006进行的短梁三点弯曲试验得到的每个GFRP试件的层间剪切强度也受到循环条件的影响。
