采用碳纤维增强的乙烯酯和环氧树脂制造了[90°/±15°]缠绕层压的高压容器。设计了一个实验装置来测试容器的破裂压力。试验结果表明，与环氧树脂增强容器相比，碳/乙烯基复合容器的极限压力更高。利用数字图像相关技术进行的全场应变测量表明，碳/乙烯基材料损伤的发生和扩展存在延迟。此外，通过x射线显微断层扫描系统、激光显微镜和扫描电镜观察，碳/乙烯基容器比碳/环氧树脂容器应变分布更均匀，环形裂纹更少、更短。
High pressure vessels with winding lamination of [90°/±15°] were manufactured adopting a vinylester and an epoxy resin reinforced with carbon fibres. An experimental setup was design to test the vessels up to the burst pressure. The tests results demonstrate a higher ultimate pressure of the carbon/vinylester composite vessel with respect to the epoxy reinforced counterpart. The full field strain measurements by the digital image correlation technique show a delayed of the initiation and propagation of the damage in the carbon/vinylester. Moreover, the carbon/vinylester vessel performed more homogeneous strain distribution with less and shorter hoop cracks than the carbon/epoxy one, as observed also with an X-ray micro tomography system, a laser microscope and a scanning electron microscope.
