Contribution of Longitudinal GFRP Bars in Concrete Cylinders under Axial Compression
Contribution of longitudinal glass fiber-reinforced polymer (GFRP) bars in concrete columns under compression has been ignored by current design guidelines. This paper challenges this convention by testing 21 concrete ... -
Green Sandwich Composites Fabricated from Flax FRP Facings and Corrugated Cardboard Cores
Composite sandwich beams and panels made of fiber-reinforced polymer (FRP) and lightweight, low-density core materials have been shown to be effective in reducing weight and increasing strength and stiffness in a variety ... -
Long-Term Tensile Properties of Natural Fibre-Reinforced Polymer Composites: Comparison of Flax and Glass Fibres
Despite of significant research on the mechanical properties of fibre-reinforced polymer composites made of natural fibres, long-term performance of the natural fibre composites against moisture and other environmental ... -
Cumulative Impact Energy Absorption of Sandwich Panels with Foam Cores and Flax FRP Facings
In this paper, the cumulative energy absorption of sandwich panels constructed of foam cores and flax fiber-reinforced bio-based polymer (FFRP) faces is studied. Nine sandwich panels were constructed and tested under varying ... -
Lateral Behaviour of Concrete-Filled FRP Tube Piles
Applications of fiber-reinforced polymer (FRP) composite piles are rapidly gaining traction in Canada and around the world. FRP piles offer several advantages compared to traditional piles, the most important of which is ... -
