Effect of short glass fiber on shear capacity for shallow wide reinforced concrete beams

open access: yesJournal of Engineering and Applied Science, 2021
Shallow wide reinforced concrete beams are used in modern buildings especially in residential building structures. According to current Egyptian Code Practice 203-2018; the characteristic of a shallow wide concrete beam is that the cross-section width (b)

Performance of concrete beams partially/fully reinforced with glass fiber polymer bars

open access: yesJournal of Engineering and Applied Science, 2021
One of the major advantages of using glass fiber-reinforced polymer bars as a replacement to the traditional steel-reinforced bars is its lightweight and high-resistant to corrosion.

Experimental Study of the Flexural and Compression Performance of an Innovative Pultruded Glass-Fiber-Reinforced Polymer-Wood Composite Profile. [PDF]

open access: yesPLoS ONE, 2015
The plate of a pultruded fiber-reinforced polymer or fiber-reinforced plastic (FRP) profile produced via a pultrusion process is likely to undergo local buckling and cracking along the fiber direction under an external load. In this study, we constructed

Influence of matrix toughness and interfacial strength on the toughness of epoxy composites with ductile steel fabric reinforcement [PDF]

open access: yes, 2015
In the last decades, several studies have been performed on polymers reinforced with steel cords or wires. However, the diameter of these steel reinforcements was still quite large (200 micron and more).

Delamination resistant composites by interleaving bio-based long-chain polyamide nanofibers through optimal control of fiber diameter and fiber morphology [PDF]

open access: yes, 2020
In this work an innovative electrospinning system is proposed that simultaneously has an adequate temperature resistance, a high increase in mode I (þ51%) and mode II (þ96%) delamination performance and can be commercially produced.

Screen-Printed Interdigital Structure on Flexible RTM6 Substrate

open access: yesProceedings, 2017
Ideally, for non-invasive sensor integration in fiber reinforced composites, sensors should be made of resin or fibers. For the first time, the curing degree of RTM6 resin in Glass Fiber Reinforced Polymer (GFRP) is measured with a sensor made of the ...

Evaluation of Fire Resistance of Polymer Composites with Natural Reinforcement as Safe Construction Materials for Small Vessels

open access: yesApplied Sciences, 2023
In small vessels, for example, yachts, polymer–glass composites are mainly used for their construction. However, the disposal and/or recycling of composite units is very difficult.
