Abstract
An experimental investigation using drag-out tensile test to calculate the interfacial shear strength for different embedded lengths of Kevlar and carbon fibers reinforced epoxy matrix with nanoclay (kaolinite) for different ratio weight, the interfacial shear strength increased by with increasing of embedded length and ratio weight fraction of nanoclay that adding to epoxy matrix.
Highlights
The efficiency of fiber-reinforced composites is often controlled by the properties of the fiber-matrix interface Good interfacial bonding or perfect adhesion, to ensure load transfer from matrix to reinforced fiber, is a primary requirement for effective use of reinforcement properties a fundamental understanding interfacial properties and quantitative characterization of interfacial
A large number of analytical techniques have been developed for understanding interfacial adhesion of Kevlar and carbon fibers reinforced epoxy matrix such as drag-out adhesion test of U-shaped single fiber specimen, the interfacial shear strength which interfacial parameter calculated used by Kelly-Tyson-analytical model [4]
One of the more important tests is dragging out and using to calculate peak force with displacement to get interfacial shear strength this test, the theory was putting by Nuriel model
Summary
The efficiency of fiber-reinforced composites is often controlled by the properties of the fiber-matrix interface Good interfacial bonding or perfect adhesion, to ensure load transfer from matrix to reinforced fiber, is a primary requirement for effective use of reinforcement properties a fundamental understanding interfacial properties and quantitative characterization of interfacial. A large number of analytical techniques have been developed for understanding interfacial adhesion of Kevlar and carbon fibers reinforced epoxy matrix such as drag-out adhesion test of U-shaped single fiber specimen, the interfacial shear strength which interfacial parameter calculated used by Kelly-Tyson-analytical model [4]. By adding kaolinite as nanocly to the epoxy matrix for increasing the bond between fiber and matrix due to increasing the interfacial shear strength at the interface[5]
