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.

将使用轻巧的燃油箱作为下一代运输设备需要长时间的耐用性和高强度。当从液化气体的液化气罐中排出时，储罐物质通过空化而造成了损坏。这项研究旨在损害由储罐中的空化引起的储罐材料的过程。玻璃纤维增​​强塑料（GFRP）被认为是储罐材料。 R-134a通过瞬时降压煮沸在273 K时用作压力型气体。 GFRP的标本浸入了循环条件下。 GFRP标本表面的激光显微镜测量结果揭示了循环空化条件的空缺深度的复杂变化。根据JIS K 7057：2006获得的每个GFRP标本的层间剪切强度也受环状条件的影响。
