A new generation of concrete highway bridges has recently been built in Canada using new design concepts and advanced materials for reinforcing and prestressing concrete . This paper describes briefly the design and construction of three bridges. The first smart concrete highway bridge (Centre Street, Beddington Bridge, Calgary, Alberta) is prestressed by carbon fiber reinforced plastic (CFRP) ...

This study compared the initial and final failure loads and failure modes of indirect resin composite laminate veneers with and without fiber reinforcement. Forty intact lower canines received standard laminate preparations and were randomly assigned into four test groups (n=10). In Group 1, indirect resin composite veneers were repaired with two layers of preimpregnated bidirectional glass fib...

Due to their compact size, sensitivity, and ability to be multiplexed, intrinsic Fabry-Perot interferometers (IFPIs) are excellent candidates for almost any multi-point temperature or strain application, and it is well-known that using a single-mode lead-in fiber, a multimode fiber section as the Fabry-Perot cavity, and an additional single-mode fiber as the tail results in a structure that gen...

Physical, mechanical, chemical, and thermal properties of sugar palm (Arenga pinnata) fiber were investigated for specimens obtained from three different locations: Kuala Jempol (Peninsular Malaysia), Tawau (West Malaysia), and Tasik Malaya (Indonesia). The morphology of the fiber were observed through scanning electron microscopy (SEM), the thermal properties by thermogravimetric analysis (TGA...

due to the existence of fibrous materials such as plastic fragments, the strength anisotropy of municipal solid waste (msw) materials is the main source of differences between their mechanical response in direct shear and triaxial apparatus. as an extension of earlier research on the mechanical behavior of msw using a large traixail apparatus, results presented in shariatmadari et al. [1] and k...

This study evaluates the mechanical strength of 3D-printed objects composite material. The material considered in this comprises onyx as base with glass fiber and carbon internal reinforcements. 3D printing using materials generally involves laminating reinforcements form layers within printed part. To analyze effect such on parts, specimens were prepared by varying number arrangement condition...

In this study, the mechanical and tribological properties of unidirectional glass fiber/polyester resin carbon fiber / polyester composite materials reinforced with boron particles have been investigated by experimental methods. Composite sheets were produced hand lay-up method using mixed boroxide (H3BO3) a specific gravity 1.51 g/cm3 molecular weight 61.83 g/mol, which utilized as particles. ...

frps (fiber reinforced polymer) possess many favorable characteristics suitable and applicable for construction industry when compared with steel reinforcement. there are new ideas to use frps as longitudinal or transverse reinforcement for new concrete elements particularly for bridge decks or beams. although high tensile strength of frp is main characteristic for applications at both areas, i...

Aims and Objective Denture fractures are a common problem in clinical practice. Despite the use of different reinforcement materials (metal wires, metal plates, and various types of fibers) for denture repairs, recurrent fractures are still common. The purpose of this study was to compare the maximum flexural loads of the heat-polymerized denture base resin when repaired with autopolymerizing r...

Reinforcement of fibrous composites by stiff particles embedded in the matrix offers the potential for simple, economical functional grading, enhanced response to mechanical loads, and improved functioning at high temperatures. Here, we consider laminated plates made of such a material, with spherical reinforcement tailored by layer. The moduli for this material lie within relatively narrow bou...
