In-plane and interlaminar shear properties of carbon/epoxy laminates

Composites Science and Technology, 1995
Abstract Carbon/epoxy laminates of three different lay-ups have been tested to measure both in-plane shear and interlaminar shear (ILS) properties by the Iosipescu shear method. A reasonably pure state of shear strain is achieved in the region between the roots of two V-notches in all the laminates.

Modified Short Beam Shear Test for Measurement of Interlaminar Shear Strength of Composites

Journal of Composite Materials, 2003
A modified short beam shear test was proposed to measure interlaminar shear strength (ILSS) of fiber reinforced carbon-carbon composites (CCC). The direct loading in the short beam shear (SBS) test is replaced by an indirect loading through a rubber pad and an aluminum seat.

Interlaminar shear properties of polymer matrix composites: Strain rate effect

Mechanics of Materials, 2007
Studies are carried out on interlaminar shear behavior of typical polymer matrix composites under high strain rate shear loading. Torsional split Hopkinson bar (TSHB) apparatus is used for the studies in the shear strain rate range of 496–1000/s ...

Investigation of the In-Plane Shear and Interlaminar Shear in Woven Roving Composites

Fibers and Polymers, 2021
In this paper a computational and experimental study to determine the in plane and interlaminar shearing stress-strain response of a composite material is performed. It is known that the above mentioned shear properties can be directly determined from shear and torsion experiments but also can indirectly be determined from bending and tension ...

Interlaminar Shear Strength of Cloth-Reinforced Composites

Experimental Mechanics, 1988
A test specimen to define the interlaminar shear strength of cloth-reinforced composite materials is developed. The specimen is a hollow circular cylinder which is subjected to torsion. The experiment is employed for the determination of the warp-normal shear strength of a graphite-fiber carbon-matrix composite material, It is demonstrated that the ...

Size Effects in Interlaminar Tensile and Shear Strength of Unidirectional Glass Fibre/Epoxy

Journal of Reinforced Plastics and Composites, 1996
Curved beams tested in four point bending were used to measure interlaminar tensile strength, and straight beams loaded in three point bending to measure interlaminar shear strength.

Influence of Fiber-Matrix Adhesion on Mechanical Properties of Graphite/Epoxy Composites: II. Interlaminar Fracture and Inplane Shear Behavior

Journal of Reinforced Plastics and Composites, 1999
A comprehensive experimental study was conducted to determine the effects of fiber-matrix adhesion on Mode I and Mode II interlaminar fracture toughness, interlaminar shear strength, and inplane shear properties of the graphite/epoxy composites with ...

Interlaminar shear strength of fibre-reinforced composites

Composites, 1975
Abstract An analysis is given of the stress distribution between two grooves cut on opposite faces of a fibre-reinforced composite when a tensile stress is applied to the ends. If this loading system is used to produce failure in shear, it has been shown that the fracture surface is always on the centre plane of the test piece.

The Effect of Strain Rate on Interlaminar Shear Properties

45th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics & Materials Conference, 2004
Specimens were created using an Applied Poleramic SC-15 Epoxy Resin and an S2-Hexcel 4533 weave. A total of 40 layers were stacked in an 18 by 30 inch panel and the resin was infused using a vacuum assisted resin transfer method with a vacuum bag on one side.

Acoustic Emission and Interlaminar Shear Strength

1986
Acoustic emission from glass cloth reinforced epoxy during interlaminar shear test has been studied in order to clarify the interlaminar properties. At liquid nitrogen temperature the serration was found on load-displacement curves which corresponds with step wise AE increase.
