Fibre-reinforced plastic composites. Determination of interlaminar strength and modulus by double beam shear test
| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 30 |
This document specifies a procedure for determining the interlaminar strength, and modulus, by double beam shear (DBS) tests of fibre-reinforced plastic composites.
The method is suitable for use with glass or carbon fibre-reinforced plastic composites with thermoset matrices, providing an acceptable interlaminar failure is obtained.
This document only applies to laminate with a symmetrical and balanced lay‐up as it avoids bending/twisting or bending/extension coupling deformations (see 6.2). The preferred lay-up is unidirectional, with fibres aligned along the specimen (axial) length.
The suitability of the test for specific lay-ups, matrices and fibres (e.g. natural) are assessed by trial tests to ensure the correct delamination failures are obtained.
