Advanced fibre-reinforced polymer (FRP) composites for the rehabilitation of timber and concrete structures: assessing strength and durability

Parameters influencing the impact response of fiber-reinforced polymer matrix composite materials: A critical review

“…The influence of various types of fiber systems on the impact response of composite materials is huge. Fiber reinforcements are the key load-bearing elements, offering the structure with the greater part of its strength and stiffness [43]. Presently, numerous varieties of fiber reinforcements are available.…”

Fatigue Behavior of Glass Fiber-Reinforced Polymer Bars after Elevated Temperatures Exposure

“…As a new type of structural material in civil engineering, fiber-reinforced polymer (FRP) has become an important supplement to traditional materials in civil engineering due to its excellent mechanical, physical and chemical properties [ 1 , 2 , 3 ]. At present, FRP composite materials in civil engineering mainly include four categories based on the form of application: FRP strengthened structures, FRP ribs and cables to replace steel bars and steel cables, FRP combined with traditional materials and full FRP structures [ 4 , 5 , 6 , 7 , 8 ]. Furthermore, as a form of FRP composite materials, FRP bars are attractive for wide use in civil engineering structures especially where steel bars and/or pre-stressed steel bars are not suitable due to highly corrosive environments or where an electromagnetic transparency of structure are required [ 9 , 10 , 11 , 12 ].…”

Local FRP reinforcement of existing timber beams

“…Bond test results (Section 5.1) have demonstrated a bond strength of 9.13-10.2 MPa for CFRP reinforcements. Considering the ageing effects [48][49] on the bonding and usual factors of safety, it is suggested to calculate the bonding lengths using a maximum allowable average shear stress of 3 MPa (1/3 of the bond strength), with a minimum length of the FRP sheet of three times the outer knot diameter d (Fig. 17).…”
