STRENGTHENING OF REINFORCED CONCRETE BEAMS WITH CARBON FIBER REINFORCED POLYMERS [PDF]
ERJ. Engineering Research Journal, 2009 Strengthening of structures is a complex task. Different systems can be used in order to utilize the fiber reinforced polymer in the most efficient way. Two techniques for surface reinforcement in reinforced concrete beams are addressed in this paper, namely, extemally bonded laminates (EBL) and near surface mounted strips (NSM).

Torsional Strengthening of RC Beams with CFRP Wrap
Tikrit Journal of Engineering Sciences, 2013 Many studies have been performed in recent years on strengthening RC (reinforced concrete) beams in shear and bending using FRP (Fiber Reinforced Polymer) wraps and laminates. Torsional strengthening, however, has not attracted as much attention.

Carbon Fiber Reinforced Polymers for High-dynamic Testing Machines
Procedia CIRP, 2017 Main design objective of high-dynamic multiaxial testing machines is a high fundamental frequency. Carbon fiber reinforced polymers (CFRP) offer outstanding weight-specific properties and high design freedom. They are thus a promising choice for the development of novel testing machines.
