Bending Performance and Reinforcement of Rocker Panel Components with Unidirectional Carbon Fiber Composite

Shear and bending performance of carbon fiber composite sandwich panels with pyramidal truss cores

Structural performance in direct (pure) shear and three-point bending was investigated for sandwich panels with a carbon fiber pyramidal truss core. Analytical estimates for sandwich panel strength for each loading condition were presented for possible competing failure modes. In the experimental part of the study, pyramidal truss cores were made using the hot press molding technique and then a...

Damage Detection of Carbon Fiber-reinforced Concrete Under Bending Test

Optical Fiber Embedded in Epoxy Glass Unidirectional Fiber Composite System

We aimed to embed silica optical fibers in composites (epoxy vinyl ester matrix reinforced with E-glass unidirectional fibers in mass fraction of 60%) in order to further monitor the robustness of civil engineering structures (such as bridges). A simple system was implemented using two different silica optical fibers (F1-double coating of 172 µm diameter and F2-single coating of 101.8 µm diamet...

Reinforcement of Fiber-reinforced Composite Crowns with Variant Margin Designs

Fiber-reinforced composite restorations provide excellent esthetics; however, little is known regarding the influence of margin design on marginal accuracy and breaking strength for this type of crown. This study evaluated the effect of variations in tooth preparation design on the marginal accuracy and breaking strength of fiber-reinforced composite crowns. Three metal dies with a total conver...
