Hierarchical carbon-nanotube (CNT)-based composites have significant potential to expand the performance and functionality of aerospace composite structures. Notably, circumferentially aligned CNT arrays have previously been grown on woven alumina filaments to form a "fuzzy fiber" reinforced plastic (FFRP) architecture with demonstrated improvements in interand intra-ply mechanical properties a...
in this paper the traditional covering plaster of masonry buildings is supplied with polypropylene and steel fiber to enhance their seismic behavior. the plaster mix proportion is determined by some initial mortar tests. also, one story, single span masonry building specimen plastered with different mortars is tested on a shaking table 8 times under a seismic input and the performance of the sp...
objective : the aim of this study was to evaluate fracture characteristics of rigid two-tooth segments splinted with fiber reinforced composite (frc), with and without application of simulated masticatory forces. material and methods: in this experimental study, 80 extracted maxillary bicuspids were joined in pairs from the buccal aspect using frc. the specimens were divided into two groups. in...
A Microwave Probe for the Non-destructive Determination of the Steel Fiber Content in Concrete Slabs
A non-destructive measuring technique to determine the fiber content in hardened steel fiber reinforced concrete is presented. The technique is based on an accurate open-ended coaxial probe reflectometry method for measuring the effective permittivity of the fiber reinforced concrete and on a mixing rule from the classical homogenization theory for deriving the fiber content from the measured p...
در این پایان نامه تاثیر مقاوم سازی با استفاده از ) frp(fiber reinforced polymer و مقایسه آن با روش مقاوم سازی) trm(textile reinforced material روی ستون های بتن مسلح بررسی خواهد شد.. هدف مقایسه میزان جابجایی نسبی و نیز شکل پذیری در این دو روش میباشد. از آنجایی که رزین های اپوکسی به کار رفته در frp منشا نقایصی برای این ماده بودند trm ها به عنوان یک راه حل و با رویکرد حذف رزین های اپوکسی گسترش یاف...
Composite materials are continuously replacing the conventional and alloys owing to their weight reduction. Biodegradable fiber-reinforced composite one of prime attractions researcher due easy availability low cost. During drilling these Natural Fiber Reinforced Plastic composites (NFRP), delamination surface roughness problems encountered, which be minimized get better output by adopting diff...
background and aims. the mechanical properties of fiber-reinforced composite fixed partial dentures (fpds) are affected by fiber impregnation. the aim of this in vitro study was to compare the fracture resistance of composite fixed partial dentures reinforced with pre-impregnated and non-impregnated fibers. materials and methods. groups (n=5) of three-unit fiber-reinforced composite fpds (23 mm...
Love-type wave generation in a fiber-reinforced medium placed over an inhomogeneous orthotropic half-space is analysed. The upper and lower boundary surfaces of the fiber reinforced medium are periodically corrugated. Inhomogeneity of half-space is caused by variable density and variable shear modules. Displacement components for layer and half-space are derived by applying separable variable t...
