A dataset of shear strength of soy-protein adhesive

Bonding strength evaluation: The shear strength and tensile strength of the plywood was tested using a universal testing machine at a rate of 5 mm/min through the system project “Plastics-Determination of tensile properties”. Because the maximum tensile force limit of the machine is 5000 N, the adhesion area of plywood is set at 3cm² or 1cm2. The maximum force (F) applied to joints before failure was recorded. The resulting shear strength was calculated by dividing the F by the joint overlap area (A). The number of test samples for each data point is at least 10, ensuring that the fracture of each sample is caused by the adhesive layer rather than the substrate, and discarding any outliers that deviate from the average value by more than 3 MPa.
