Abstract
Insulation systems in liquefied natural gas carriers (LNGCs) are vulnerable to sloshing impact and fatigue loads because of waves. If gas leaks into the primary barrier, the flexible secondary barrier (FSB) prevents the leakage of gas in this system. The fatigue strength of a composite FSB largely depends on the behavior of its materials. In this study, a new containment system is proposed for the FSB with the use of aramid fibers to improve its fatigue strength by replacing the conventional E-glass with aramid ones. In its manufacturing, the ratio of aramid to E-glass fibers was varied for an optimum design of the FSB. Fatigue tests showed that the FSB with aramid fibers was superior to that with E-glass ones.

Abstract This study examined the fatigue performance of a LNG (Liquefied Natural Gas) insulation system with a newly developed metallic secondary barrier used in Mark-III type LNG carriers. In particular, the conventional secondary barrier used in Mark-III type carries a risk of leakage and fatigue failure owing to the thermal and cyclic loads. In this respect, the secondary barrier requires superior tightness, high strength, and fatigue performance at cryogenic temperatures. To improve the tigh...

Abstract The fatigue lifetime of composite pipe subjected to cyclic internal hydrostatic pressure with variable amplitudes is considered. Progressive damage modeling technique is utilized on the basis of stiffness degradation for monitoring damage progress in composite structure. The modeling which consists of three different phases as stress analysis, damage estimation and mechanical properties degradation is implemented in parallel with the random generation of fatigue loading pattern. All inv...

Abstract In this work, the aramid fiber/epoxy interfacial normal bonding property and interfacial shear property were estimated by transverse fiber bundle tensile (TFBT) test and 45° fiber bundle tensile (45FBT) test, respectively. The fracture surfaces of the fiber bundle samples after the mechanical test were observed to investigate the micro failure mechanisms. The interfacial debonding was found coupled with fibrillation of the fiber surface due to the apparent skin/core structure of aramid ...

A probabilistic model involving the randomness of basic design parameters was presented to predict the probabilistic strength of a typical composite double-lap single-bolt joint. In the probabilistic model, statistical models of the random parameters including geometrical dimensions, fiber orientation angles and material properties were constructed. In addition, a parametric failure prediction model employing a modified characteristic curve method was established. Static tensile tests of fifteen...

Abstract Energetically critical points in thermally insulating building envelopes are caused by penetrations of building interior concrete slabs through the envelope insulation layers to create external balconies. A new highly insulating balcony thermal break element has been developed which enables both structural continuity and thermal insulation in the envelope’s insulation layer. The element is composed of combined structural and thermally insulating AFRP/GFRP loop and sandwich components. T...

Abstract Fibre-reinforced composites are rapidly increasing their market share in structural applications. Nevertheless, this increase would be much stronger if reliable failure predictions were available. These predictions are not only insufficiently reliable for complex loading of multidirectional composites, but even for longitudinal tensile failure of unidirectional (UD) composites. Since composite failure usually coincides with longitudinal failure of a 0° ply, the reliability often hinges ...

Abstract Tension–tension fatigue performances of T700/MTM46 composite laminates were investigated in this paper and the fatigue limit was determined. Failure modes of the fatigue specimens are mainly characterized by severe delamination throughout the whole gauge length while the static tension specimens exhibit brittle fractures within a small region. The stiffness degradation shows a quasi-linear slow decline during approximately 0–80% fatigue life and has a sharp decline since 80% fatigue lif...

We investigate new numerical results of thermal buckling for functionally graded plates (FGPs) with internal defects (e.g., crack or cutout) using an effective numerical method. The new formulation employs the first-order shear deformation plate theory associated with extended isogeometric analysis (XIGA) and level sets. The material properties of FGPs are assumed to vary continuously through the plate thickness obeying a power function. The internal defects are represented by the level sets, wh...

Energetically weak points in thermally insulated building envelopes are formed by thermal breaks that are implemented to structurally connect external balconies to internal slabs. Current thermal breaks comprise stainless steel bars that penetrate the insulation layer and thus cause significant thermal losses. A new thermal break composed of highly insulating aramid and glass fiber-reinforced polymer ( AFRP and GFRP) components and aerogel granulate insulation materials was developed and the fir...

Abstract A sensitivity analysis (SA) has been conducted to examine the influence of uncertain input parameters on the fracture toughness of polymeric clay nanocomposites (PNCs). In order to predict the macroscopic properties of the composite, a phase-field approach has been employed considering six input parameters. For computationally efficiency, the SA is performed based on a surrogate model. Screening methods of the Standardized Regression Coefficients and the Regionalized Sensitivity Analysi...
