This paper presents a light and compact optical fiber Bragg Grating sensor for DC and AC magnetic field measurements. The fiber is coated by a thick layer of a magnetostrictive composite consisting of particles of Terfenol-D dispersed in a polymeric matrix. Among the different compositions for the coating that were tested, the best magnetostrictive response was obtained using an epoxy resin as ...

Ceramic powder (zirconia) was mixed with binder consisting polypropylene, paraffin and stearic acid in elastic extruder. Steady and oscillatory shear flow properties of these materials in the molten state were measured on a cone-plate rheometer; parallel superposed steady and oscillatory shear flow experiments were also carried out. Moreover, flow properties at high shear rates were measured on...

Composite wood products have traditionally relied on thermosetting polymers like phenol-formaldehyde and urea-formaldehyde resins as binders. The continuing need to effectively utilize lignocellulosic fiber from lowquality hardwoods and from recycling streams has prompted consideration of new composites based on thermoplastic polymers [ 1,2]. Much of the development effort has focused on commod...

Binder stabilized preforms are getting increased attention in the wind turbine industry with aim to increase automation production of large blades. In this context a preform is stack dry unidirectional glass fiber non-crimp fabrics (UD-NCF), which consolidated using polymeric binder. The manufactured separate mold, and subsequently placed main blade mold. During placement preforms, wrinkling ma...

A problem of determining the fiber volume fraction in fiber-reinforced strands fabric-based laminated composites is considered. As a source information about structure material, digital micrographs ground surface cross-sections are used. Methods and features analysis raster microscopic images heterogeneous material associated with variable pixel brightness blurring "fiber-binder" boundaries dis...

The purpose of this study was to evaluate the impact fiber types, binder content, and their dosage rates on volumetric properties laboratory performance asphalt mixtures. One mixture (control) three types (Basalt, Fiberglass, Carbon) were used. Two different considered 0.15% (recommended rate) 0.30% by total weight. Furthermore, a novel experimental methodology developed implemented consisting ...

Binder drainage test is widely used to set an upper limit to the design binder content of porous asphalt. However, the presence of high amount of fine particles in the drained binder may affect the accuracy of the test result. This paper presents a study to characterize the composition and particle size distribution of fine particles accumulated in the drained binder. Fine aggregates and filler...

Gas evolved from the thermal decomposition of the binder can greatly deteriorate the quality of sand castings. Binder gas models used in casting simulations require knowledge of the binder gas mass and molecular weight evolution, but available data are limited. In the present study, the mass and molecular weight of gas evolved from phenolic urethane no-bake (PUNB) bonded sand are measured as a ...
