In particular, the allowable spacing of the tension reinforcements in the PSC members reinforced with 550 MPa nonprestressed reinforcements is always smaller than those reinforced with 420 MPa nonprestressed reinforcements.
Test results show that beams reinforced with hybrid reinforcement perform superior than those reinforced only with steel in all aspects.
Due to the differences in the mechanical properties of FRP and steel reinforcement, the compression behavior of concrete columns reinforced with FRP reinforcement may differ from those reinforced with steel.
Due to the relatively low modulus of elasticity of FRP bars, concrete members reinforced longitudinally with FRP bars experience reduced shear strength compared to the shear strength of those reinforced with the same amounts of steel reinforcement.
Specimens reinforced by EMM showed better ductility than those reinforced by WWM and even after increasing the reinforcement ratio of WWM, the situation did not change.
The major classes of composites include those made up of discrete layers (sandwich laminates) and those reinforced by fibrous mats, woven cloth, or long, continuous filaments of glass or other materials.
The ceramic graphite reinforced composite has better machinibility than those reinforced with SiCp composites.
In addition to improving paper products directly, the new cellulose nanofibers could help create reinforced plastic composites cheaper than those reinforced by carbon fibers, the researchers say.
The fracture toughness of Al2O3 ceramics reinforced with SWCNTs was significantly better than those reinforced with MWCNTs.
In the partial PSC sections with the PPRs 67 or 50%, the Δf ps values were higher when they were reinforced with 550 MPa reinforcing bars (Grade 80) than those reinforced with 420 MPa reinforcing bars (Grade 60).
