Effect of Veil Interlayer Type and Placement on the Mechanical Response of Carbon and Glass Fiber/Epoxy Composites

Polymer Composites, EarlyView.
Veil interlayers of five different chemistries (PI, FG, PPS, PEI, PEEK) were placed at two through‐thickness positions in carbon and glass fiber/epoxy laminates and evaluated under interlaminar shear (ILSS), three‐point bending (3PB) and axial buckling loading. The optimum placement was found to be loading mode dependent: near‐surface placement favored

Additive Manufacturing of Glass Fiber‐Reinforced Polypropylene and Its Behavior Under Controlled Hydrogen Exposure

Polymer Composites, EarlyView.
Experimental and numerical assessment of GFRPP under lower experimental hydrogen pressures using tensile testing, SEM analysis, and hydrogen uptake estimation. ABSTRACT Glass fiber‐reinforced polypropylene (GFRPP) composites are increasingly explored for hydrogen transport and storage due to their lightweight nature and corrosion resistance.

Fully reversible reinforcement of softwood beams with unbonded composite plates [PDF]

, 2016
In this paper, results of flexure tests aimed at improving the structural behaviour of softwood beams reinforced with unglued composite plates and at developing an effective alternative to the use of organic resins are presented.

An Integrated Statistical and Machine Learning Framework for Predicting the Dry Sliding Tribological Behavior of CFRP and GFRP Composites Under Environmental Aging and Loading Conditions

Polymer Composites, EarlyView.
The graphical abstract presents the experimental and data‐driven framework used to investigate the dry sliding tribological behavior of CFRP and GFRP composites. The effects of seawater, engine oil, diesel fuel, aging time, and normal load on the specific wear rate (SWR) and coefficient of friction (COF) were evaluated using pin‐on‐disc tests, ANOVA ...

Fiber‐Reinforced Bio‐Epoxy Composites: Degradation Mechanisms in Saline Environment

Polymer Composites, EarlyView.
Constituent level degradation of bio‐epoxy composites after saline aging. ABSTRACT This study examines the degradation behavior of bio‐epoxy composites reinforced with glass, basalt, carbon, and flax fiber yarns in a simulated saline environment. Fiber yarns and composite samples were exposed to 3.5% NaCl solution at 60°C for up to 3000 h.

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Experimental and numerical investigation on the flexural response of GFRP‐reinforced SFRC beams

Structural Concrete, EarlyView.
Abstract In order to address the challenges related to the deformability and ductility of concrete beams reinforced with fiber reinforced polymer (FRP) bars, an alternative solution involving steel fiber reinforced concrete (SFRC) has been proposed. In the present study, a total of seven beams—including one steel‐reinforced reference beam and six glass

Side‐by‐side long‐term performance assessment of GFRP‐ and steel‐reinforced concrete bridge decks

Structural Concrete, EarlyView.
Abstract The corrosion‐induced deterioration of steel‐reinforced bridge decks is a service life concern, especially in cold regions, where the use of deicing chemicals is common. To address this issue, glass fiber‐reinforced polymer (GFRP) reinforcement has received growing attention, owing to the GFRP's resistance to conventional corrosion.
