Summary: This article presents the design, prototyping, and burst test of a thermoplastic composite overwrapped pressure vessel. New models for composite stacking in the dome area are proposed and compared to state of the art solution. The behavior of the tank during the burst test is monitored, and a time-dependent behavior is observed during a pressure plateau at 700Bars. The burst occurs at 1586 Bars in the dome area, where the model predicts the maximum fiber stress.

Summary: The fire resistance performance of steel-polymer prefabricated composite floors with a sandwich-type structure was assessed using standard fire tests and finite element analysis. A structural analysis was conducted based on temperature distributions obtained from thermal analysis. The thickness of the bottom steel plate was found to have a linear correlation with the stability rating, while the top steel plate thickness had no impact on the stability ratings. Equations for stability rating and fire resistance performance were proposed based on the analysis results.

Summary: This study investigated the failure of two steel pressure vessels during hydrostatic test at a pressure lower than test pressure. It was found that pitting corrosion at the bottom part of the vessel was the cause of cracks, and the possibility of retaining functionality using composite patch repair procedure was assessed and confirmed by experimental investigation. Recommendations were provided to prevent future failures of similar pressure vessels.

Summary: Exploration of the thermal performances of composite high-pressure hydrogen storage tanks under fire exposure is crucial for reducing the risk of tank rupture. This study conducted bonfire tests on type III tanks and presented detailed data on tank wall temperature and inner pressure. The results showed the failure pressure limits of the tanks and the consequences of exceeding these limits in fire scenarios.

Summary: Low-velocity impact tests on filament-wound composite pressure vessels revealed that the major damage modes under impact included matrix breakage, delamination, and fiber breakage. The duration of the plateau area in the impact force-time response curve increased with higher impact energies, showing that the impact resistance of filament-wound COPV was superior.

Summary: This study aimed to evaluate the sealing quality of swine small intestine using different laparoscopic radiofrequency vessel sealing devices compared to golden standard closure technique. Results showed that RFVS-1 and RFVS-3 devices provided suitable intestinal sealing, while HS and RFVS-2 should not be considered for intestinal sealing.

Summary: Two steel pressure vessels failed during hydrostatic test at a pressure lower than proof pressure, with through-wall cracks mainly initiated by excessive pitting corrosion at the bottom. Experimental and numerical investigation was carried out to propose a repair method, while non-destructive testing and microscopy were used to inspect cracks and measure wall thickness.

Summary: This study focuses on the fiber winding design and fabrication method of a carbon fiber wound composite pressure vessel with HDPE liner. The design parameters, fiber winding tensions, and pre-charge pressures were studied. A finite element analysis model was established and progressive damage analysis was conducted, obtaining the failure mode and burst pressure of the vessel. By analyzing the critical buckling load and designing the winding tensions, the pre-charge pressure was determined. A burst test was carried out to verify the effectiveness of the design and fabrication process.

Summary: The utilization of composite floor systems in modern construction enables the efficient use of materials and labor for building large floor areas. Prior experiments have shown that composite floors can exhibit surprising robustness in high temperatures, but the collapse of World Trade Center towers demonstrated the opposite. In the past two decades, extensive experimental and theoretical studies have been conducted in this field. This review summarizes different approaches in studying composite floors and discusses design and analysis methods. It also identifies remaining challenges and provides recommendations for designing composite floor systems for fire.

Summary: This paper describes a breakthrough microleaks-no-burst (mLNB) safety technology that allows explosion-free venting of hydrogen tanks in fire without the need for thermally-activated pressure relief devices. The technology involves melting the hydrogen-tight liner to prevent the double-composite wall from losing its load-bearing ability. Hydrogen then flows through microchannels in the wall and either burns on its own or with resin. Experimental validation of the technology is presented for prototypes made of carbon-carbon or carbon-glass composites. The mLNB technology eliminates catastrophic consequences of tank rupture in fire and reduces the risk of hydrogen-powered vehicles to an acceptable level.

Summary: A process and Structural Health Monitoring system was implemented on a Composite Overwrapped Pressure Vessel (COPV) for hydrogen storage at 350 bar. The study reports the effectiveness of embedding optical fibre Bragg grating (FBG) sensors for monitoring the full life cycle of the vessel, including drop-weight impact tests and pressure cycling. The FBG sensing array showed high accuracy in detecting and locating damage, and exhibited a linear response to applied pressure.

Summary: The aim of this research was to study the residual burst strength, dynamic structural response, and failure mechanism of composite overwrapped pressure vessel (COPV) subjected to low velocity impact numerically and experimentally. The study developed a three-dimensional composite pressure vessel model and predicted the impact response and residual burst strength using specific criteria. Comparison between predicted and testing results showed a good correlation.

Summary: Little attention has been given to the effect of geometric imperfections on the fire resistance of prestressed continuous steel-concrete composite beams (PCCBs). Therefore, this paper presents findings from fire tests on PCCBs with initial geometric imperfections (IGIs), investigating their impact on fire response. The results show that PCCBs with flexural-torsional buckling as an IGI have increased mid-span deflection and decreased critical temperature, leading to faster failure. In addition, the side-support reactions decrease initially and then gradually increase during fire exposure. Finite element models were also developed to further study the effect of IGIs on the fire response of PCCBs.
