A mold is configured to make several identical single lap shear test samples according standards at one time. The mold can be made from aluminum and cast pieces of silicone rubber. The mold's shorter sides have slots designed to hold rigid substrates. The rigid substrates are inserted into the slots after the area to be bonded has been coated with adhesive. The opposing slots for each sample are offset so that the substrates overlap by the prescribed amount in the standard in the center of the mold. Spacer pieces are provided between the substrates. The slots and spacer pieces hold the substrates rigidly together to ensure a thin adhesive bondline between the two rigid substrates.
