Novel Recyclable Hierarchical Carbon Fiber/Epoxy Composites: Preserving Fiber Length and Orientation Using Elium

Polymer Composites, EarlyView.
Schematic illustration of a hierarchical recycling approach that preserves reinforcing fiber orientation. ABSTRACT Current recycling methods for polymer matrix composites produce short, unoriented carbon fibers, limiting their use to intermediate‐strength applications.

Computational intelligence model for predicting the compressive strength of FRP‐confined concrete column

Structural Concrete, EarlyView.
Abstract Fiber reinforced polymer (FRP) wrapping technology is commonly used to enhance the compressive strength (CS) of reinforced concrete (RC) members. Accurate prediction of the compressive strength of FRP‐confined concrete columns is crucial for optimizing structural design and helps reduce the time and costs associated with physical testing ...

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Fire Endurance of Concrete Elements Reinforced with GFRP Bars

Advanced Materials Research, 2013
Fire engineering is primarily to prevent loss of life or injury during a fire. Obviously the best way to achieve this is to prevent ignition, minimizing fire spread and smoke, dying the fire before it has fully developed. When this is not possible, when the fire is fully developed, structural elements must guarantee sufficient fire resistance.
