This paper presents an experimental investigation on the influence of confinement method and specimen end condition on axial compressive behavior of fiber reinforced polymer (FRP)-confined concrete. A total of 12 aramid FRP (AFRP)-confined concrete specimens with circular cross-sections were tested. Half of these specimens were manufactured as concrete-filled FRP tubes (CFFTs) and the remaining half were FRP-wrapped concrete cylinders. The effect of specimen end condition was examined on both CFFTs and FRP-wrapped specimens. This parameter was selected to study the influence of loading the FRP jacket on the axial compressive behavior. In this paper the experimentally recorded stress-strain relationships are presented graphically and key experimental outcomes discussed. The results indicate that the performance of FRP-wrapped specimens is similar to that of CFFT specimens and the influence of specimen end condition is negligible.

Effective Use

Woven composites have been increasingly employed in engineering applications. For effective use of woven composites in engineering applications, it is essential to fully understand the mechanical behavior. In the present study, both tensile and compressive behavior of a carbon/glass hybrid woven composite manufactured by vacuum infusion process was experimentally investigated under in-plane quasi-static loading. The experiments were performed at both the axial and off-axial directions. The results indicated that the in-plane mechanical performance of the studied composite was highly directional dependent and tension/compression asymmetric.

Frictional Effects

General fibrous assemblies are made of loose fibers and air filling in the pores formed by these fibers. An important characteristic of these assemblies is their mechanical behavior under compression and release. In this paper, a unified and systematic experimental investigation was used to quantify and characterize the compressional and recovery behavior of several randomly oriented fibrous assemblies via mechanical and conductive in situ integrated measurement system. An attempt was made to characterize the curves of force, modulus, work and energy loss during compressional and recovery cycles. Considerable hysteresis occurred between the compression and release operations which is an evidence for the existence of fiber slippage and frictional effects. Work, energy loss and recovery rate of work turned out to have a nonlinear exponential relationship with cycles.
