Special Issue Information

Dear Colleagues,

Composite carbon fibers consist of multiple phases, a continuous carbon phase and additive phases. The continuous carbon fiber phase serves as the matrix, which provides the mechanical strength for the composite fibers. The additive phases including oxide particles, carbon nanotubes, organic or inorganic coatings, and graphene sheets are functional components. Such functional components allow composite carbon fibers to be useful in various fields. For example, ceramics-coated carbon fibers can improve the thermal shock and ablation property of high-temperature-resistant composite materials. Bi–Te or Sb–Te particle-containing carbon fibers demonstrate excellent thermoelectric energy conversion performance. Iron-oxide-loaded carbon fibers have been considered to be used as anode materials for rechargeable lithium batteries. Titanium oxide nanoparticle-embedded carbon fibers show photovoltaic behavior. Composite carbon fibers are also proposed for building flexible sensors and energy convertors.

The objective of this Special Issue is to provide a forum for researchers to publish important findings and exchange ideas on the fundamental studies and applications of composite carbon fibers. Research papers and review articles are welcome. The scope of the Special Issue is on, but not limited to, the following topics: composite carbon fiber processing and manufacturing technology, structure and morphology studies, mechanical testing, physical property characterization, electrochemical performance evaluation, and exploration of new applications.

In this paper, the bond performance of tensile lap-spliced Glass and Basalt Fiber-Reinforced Polymer bars is investigated in high-strength concrete. Eighteen large-scale GFRP-reinforced concrete beams were fabricated and subjected to four-point loading. Key parameters explored included bar diameter and splice length for both GFRP and BFRP reinforcement. The results indicate that the flexural capacity of GFRP-reinforced beams was comparable to that of BFRP-reinforced beams, though BFRP bars exhibited marginally superior bond and strength with concrete. The bond strength of spliced FRP bars was directly proportional to the splice length. This study also determined that characteristics of development lengths necessitate splice lengths that exceed the bar diameter 40 times to mitigate bond stress. Critical splice lengths, derived from experimental findings, were compared with existing models and code-based equations, specifically, Guide for the Design and Construction of Structural Concrete Reinforced with Fiber-Reinforced Polymer Bars (ACI 440.1R-15) and Canadian standard that provides comprehensive guidelines for incorporating Fiber-Reinforced Polymer reinforcement in concrete structures (CSA S806-12). Both codes were conservative in splice length prediction for GFRP and BFRP bars, with ACI 440.1R-15 showing greater accuracy for BFRP bars with a larger diameter. A modification factor, based on hyperbolic functions, is proposed to enhance the accuracy of ACI 440.1R-15 in predicting splice lengths for various FRP bar diameters. Full article
