Chopped strand mat and glass‐fabric‐reinforced thin and thick laminates were made from phenolic and polyester laminating resins using three modifications of a hand lay‐up method. Short‐beam interlaminar shear strengths were determined in three‐point bending at a span‐to‐depth ratio 3:1. Plane and perpendicular specimens were used. It was found that the perpendicular specimens were more useful. Interlaminar delamination energies were determined statically and dynamically. It was found that the results for the phenolic and polyester laminates cannot be simply compared because of differences in the fracture mechanism.
