Cyanate ester resins offer advantages as composite matrices because of their high thermal stability, low outgassing, low water absorption, and radiation resistance. This paper describes the results of a processing study to develop a high-strength hoop-wound composite by the wet-filament winding method using Toray T1000G carbon fiber and YLA RS-14A cyanate ester resin as the constituent material...

A plasma toroid is rotated toroidally to supersonic speeds by external means. The input power maintains the rotation and also heats the plasma. The thermoelectric effect from the resulting temperature gradient creates and maintains a poloidal magnetic field against resistive decay, confining the plasma in steady state. The shear in the rotation keeps the plasma stable to MHD kinks and interchan...

This paper presents experimental research on structural behaviour of normal and recycled aggregate concrete filled steel tube (RACFT) columns externally strengthened with carbon fibre reinforced polymer (CFRP) sheets and subjected to axial loading. A total of 22 specimens were tested to investigate the influence of the following variables: (1) tube configurations, circular or square, solid or h...

To investigate the influence of joints on stability underground opening, uniaxial compression tests and FE analyses based a microplane damage model for rocks has been conducted rock-like models with circular hole set non-persistent joints. It was found that peak strength Young’s modulus decrease increase in joint continuity factor k, variation them inclination angle β are W or V-shaped curves m...

Current design codes require long bar development length and high joint hoop ratio in reinforced concrete (RC) exterior beam-column joints using high-strength materials, which reduces constructability. This study investigated the seismic behavior of RC with insufficient hoops beam flexural bars (Grade 600 MPa) and/or concrete. Six half-scale were tested under cyclic load reversals. The test par...

It is necessary to recognize masonry domes’ behavior under gravity loads in order strengthen, restore, and conserve them. The neutral hoop plays a crucial role identifying the dome’s distinguish between its tensile compressive regions. When it comes determining position dome with same brick material, addition curve thickness, support condition located on boundary line significant parameter that...

De vroege eenentwintigste eeuw zag een golf van literaire teksten waarin de klimaatverandering centraal staat. Dit artikel bespreekt wat tegenwoordig klimaatfictie of “clifi” wordt genoemd als alternatieve vorm klimaatcommunicatie, omarmd niet alleen door literatuurliefhebbers maar ook wetenschappers en activisten die tegen grenzen het informatietekort-model aanlopen in hun pogingen om bewustwo...

The tubes and pipes manufacturing industry characterizes the mechanical properties of their products with a wide selection standards, but most them are qualitative testing methodologies. To estimate from quantitative point view there limited options in standards. In that sense, standard tensile test is preferred alternative by manufacturers, this option limits estimation for longitudinal direct...
