Analysis of the interlaminar shear strength of mica/epoxy insulations

Composites, 1984
Abstract The interlaminar shear strength of mica/epoxy layers was measured by the use of four test methods. It was found that the apparent shear strength is considerably influenced by additional stress (compressive or tensile) normal to the plane, and that the intrinsic shear strength may be determined by letting the compressive stress tend to zero ...

Modelling the effect of cracks on interlaminar shear strength

Composites Part A: Applied Science and Manufacturing, 1996
Short-beam shear tests of unidirectional carbon fibre/epoxy are analysed assuming shear deformations to be concentrated at the resin-rich interfacial layers between plies. A two-dimensional finite element model is used with linear elastic continuum elements to represent the plies, and non-linear springs to model the interfaces.

Characterization of Interlaminar Shear Strength of Ceramic Matrix Composites

Journal of the American Ceramic Society, 1993
The interlaminar shear strengths of three ceramic matrix composites have been characterized using a double‐notch shear (DNS) test. The material systems investigated are plain woven C/SiC, plain woven SiC/SiC, and cross‐plied SiC/calcium aluminosilicate‐II.

Improved quality acceptance procedure for interlaminar shear strength

Composites, 1987
Abstract An efficient and cost-effective test method has been developed for the interlaminar shear strength determination of fibre-reinforced plastics. The new technique is based on the use of a continuous beam specimen instead of the conventional, small, short beam configuration.

A Study of Interlaminar Shear Strength at Cryogenic Temperatures

1980
Interlaminar shear (ILS) strength is the load-carrying capacity of a layered filamentary composite under shear forces parallel to the layers. The term “strength” is commonly applied to a material. Actually, it is the property of a structure made from that material. A strength test is a structural test.

Interlaminar shear strength evaluation of curved composite samples

Applied Composite Materials, 1994
To assess the bonding quality between the different layers of composite rings fabricated by filament winding it is necessary to choose a useful shear test. A method for measuring the shear strength of thin curved samples is proposed herein. Stress distribution within the probe is calculated and evaluated by finite element method.

Testing the interlaminar shear strength of laminated reinforced plastics

Polymer Mechanics, 1975
An improved method of determining the interlaminar shear strength of reinforced plastics from the results of mechanical bending tests on beams of different lengths is described and the results of an experimental verification of the method on glass-reinforced textolite and longitudinal-transverse-wound (LTW) glass-reinforced plastic are presented.

The Interlaminar Shear Strength of Unidirectional Boron-Aluminum Composites

Journal of Composite Materials, 1978
The interlaminar shear strength was estimated for four types of B-A1 unidirectional composites. The shear strengths from the short beam shear test and symmetric block shear test sometimes show a considerable differ ence. It is shown that in the case of a matrix of high plasticity and (or) many defects in the shear-plane the short beam shear test gives ...

Inclined Double Notch Shear Test for Improved Interlaminar Shear Strength Measurements

Journal of Composites Technology and Research, 1998
A novel method to measure interlaminar shear strengths of composites is presented. This method uses the double notch shear (DNS) specimen and modifies the load introduction by use of a fixture. The main concept is to eliminate the compressive stress intensity at the notch roots, arising from the external load, by imposing a counteracting tensile load ...

The Edge Shear Test - An Alternative Testing Method for the Determination of the Interlaminar Shear Strength in Composite Materials

Materials Science Forum, 2015
The interlaminar shear strength is a characteristic value describing the mechanical behavior of composite materials such as laminates. Several methods for the determination of the interlaminar shear strength are described in open literature by several authors.
