This test method indicates the cutting properties in the plane of a high modulus fiber-reinforced composite materials by two procedures. As regards the procedure A, laminates stuck between two pairs of loading rails are tested. When the tension load is applied to the rails, shear forces arise in the specimen. In procedure B, laminates clamped on opposite edges with a tensile or compressive load applied to a third pair of rails in the center are tested. The application of this method is for continuous-fiber or discontinuous-fiber-reinforced polymer matrix composites in the following material forms:
- Laminates wich are composed only of woven fabric filamentary laminae with the warp direction oriented parallel or perpendicular to the mounting rails.
- Laminates wich are composed only of unidirectional fibrous laminae, with the fiber direction oriented parallel or perpendicular to the mounting rails.
- Laminates of balanced and symmetric construction, with the 0° direction oriented parallel or perpendicular to the mounting rails.
- Short-fiber-reinforced composites with a majority of the fibers being randomly distributed
