Reinforcement of flexible fibre reinforced plastic (FRP) composites with standard textile fibres is a potential low cost solution to less critical loading applications. The mechanical behaviour of FRPs based on mechanically bonded nonwoven preforms composed of either low or high modulus fibres in a thermoplastic polyurethane (TPU) matrix were compared following compression moulding. Nonwoven pr...

21 Abstract 22 23 This paper reports on the North American state-of-the-art in the use of FRP composites in concrete structures. For new 24 construction, FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for 25 a host of reasons. The principles for design and construction have been established and proposed to industry by the American ...

Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) have been developed to reinforce gluelaminated timber (glulam) beams. The FRP reinforced glulams are significantly stiffer, stronger, and have less variation in bending strength than a conventional (unreinforced) glulam of equal size. Following the technical development and model building code approval of design proc...

Abstract—It is a major challenge to build a bridge superstructure that has long-term durability and low maintenance requirements. A solution to this challenge may be to use new materials or to implement new structural systems. Fiber Reinforced Polymer (FRP) composites have continued to play an important role in solving some of persistent problems in infrastructure applications because of its hi...

The use of externally bonded fiber-reinforced polymer (EB-FRP) composites for shear strengthening reinforced concrete (RC) beams presents many challenges given the complex phenomena that come into play. Premature bond failure, behavior interface layer between FRP and substrate, brittle nature cracks, adverse interaction internal steel stirrups EB-FRP are some these phenomena. Compared to experi...

Glass fiber reinforced plastic composite materials are finding increased applications due to their excellent properties. Fiber reinforced plastic (FRP) composite materials comprise soft matrix and fiber elements. This article presents the tribological aspects of glass fiber reinforced plastic composites. The wear test is carried out for FRP in a pin-on-roller wear tester. The wear rate obtained...

Unreinforced masonry (URM) walls strengthened with composites were tested to failure at a decommissioned building in St. Louis, Missouri. The walls were subjected to out-of-plane loading. Previous work on URM as well as reinforced masonry walls strengthened with FRP laminates has shown remarkable increases in capacity and ductility. However, most of this research work has been conducted in the ...

Fibre reinforced polymer (FRP) composites are the most promising and elegant material of the present century. Their durability and integrity in various service environments can be altered by the response of its constituent i.e. fibre, polymer matrix, and the existing interface/interphase between the fibre and polymer matrix, in that particular environment. The interphase is generally manifested...

The significance of strain measurement is obvious for the analysis of Fiber-Reinforced Polymer (FRP) composites. Conventional strain measurement methods are sufficient for static testing in general. Nevertheless, if the requirements exceed the capabilities of these conventional methods, more sophisticated techniques are necessary to obtain strain data. Fiber Bragg Grating (FBG) sensors have man...
