Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) are increasingly being used to reinforce glue-laminated timber (glulam) beams, creating a new composite glulam (FRP glulam) significantly stronger in bending than a conventional (unreinforced) glulam of equal size. Large timber members have long been recognized for maintaining structural integrity in fires and this p...

The first Fibre Reinforced Polymer (FRP) implemented to a UK Railway Bridge was in 2001, since then a number of key railway bridge projects involving FRP have seen completion; six being fully FRP bridges. Although the potential use of FRP on the infrastructure was found in 1998 due to high strength to weight ratio, stiffness and good chemical resistance, the implementation of FRP to small scale...

A study of the influence of embedded circular hollow vascules on structural performance of a fibre-reinforced polymer (FRP) composite laminate is presented. Incorporating such vascules will lead to multi-functional composites by bestowing functions such as self-healing and active thermal management. However, the presence of off-axis vascules leads to localized disruption to the fibre architectu...

This paper proposes a probabilistic formulation to assess the effectiveness of the fiber reinforced polymer (FRP) retrofit schemes in enhancing the structural performance of reinforced concrete (RC) bridge columns. Two probabilistic models are proposed to predict the deformation capacities of retrofitted columns. One deformation model corresponds to the flexural failure and the other considers ...

Sustainability and environmental protection have given rise to the use of renewable biobased materials in several application areas. Fibre reinforced composites are currently gaining a high market value both structural semi-structural applications. Making these environmentally friendly, lighter will protect environment increase resource efficiency. Opposed synthetic fibres such as carbon glass,...

Many materials are gradually softened with increasing temperatures in the fire, which will cause severe damage. As a new fiber-reinforced polymer (FRP) composite, change mechanical properties of nanometer montmorillonite composite bars or plates at elevated has not been investigated. To obtain more comprehensive study FRP composites high temperatures, experimental research on fiber material und...

This study was carried out to evaluate the utilization probability of the fibrous root part (FRP) of Bletilla striata, which was usually discarded and harvesting pseudobulb part (PSP). The chemical composition, total phenolic content, DPPH radical scavenging activity, Ferric-reducing antioxidant power and tyrosinase inhibition activity were compared between FRP and PSP. Antioxidant and pro-oxid...

Fibre-reinforced polymer (FRP) matrix composites are widely used in large marine structures, and wind turbines where blade lengths now over 100 m. Composites the material of choice for small vessels due to ease manufacture, high hull girder stiffness, buckling resistance, corrosion resistance underwater shock resistance. Ships m still built using traditional steel and/or aluminium, but so far n...

Retrofits and reinforcements are needed in structures that have experienced a decline performance to continue meet their strength requirements. Reinforcement of reinforced concrete can use the method strengthening with Fiber Reinforced Polymer (FRP) which is made from synthetic fibers. But now there new innovation, namely FRP natural The fibers as basis for composite materials reduce negative i...
