The high demand for carbon composite in many industries results in an increase in the embodied energy footprint of carbon composites. Recycling technologies for carbon composites are being developed to reduce the embodied energy footprint of the material. The purpose of this research is to analyze and estimate the specific energy consumption from mechanical recycling method, specifically a ball...

Two-dimensional finite element simulations and experiments are presented to examine the ultrasonic wave propagation behavior in the corner section of CFRP (carbon fiber reinforced plastics) laminate structures. The numerical model consists of a right-angle corner section of CFRP laminate immersed in water and subjected to the ultrasonic wave incidence from its inner or outer side. The anisotrop...

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) ...

Machined surface quality determines the reliability, wear resistance and service life of carbon fiber reinforced plastic (CFRP) workpieces. In this work, the formation mechanism of the surface topography and the machining defects of CFRPs are proposed, and the influence of milling parameters and fiber cutting angles on the surface quality of CFRPs is obtained, which can provide a reference for ...

Corrugated steel web with inherent high out-of-plane stiffness has a promising application in configuring large span highway bridge girders. Due to the irregularity of the configuration details, the local stress concentration poses a major fatigue problem for the welded flange plates of high strength low alloy structural steels. In this work, the methods of applying CFRP laminate and shot peeni...

deep beams are type of beams which their behavior is different from conventional beams because of their particular type of geometry. in this paper, the retrofitting of these beams is considered and 10 deep beams are tested experimentally and discussed about retrofitting methods. experimental studies indicate that the use of cfrp bands in the direction perpendicular to diagonal cracks in compari...
