Abstract
A composite includes a first substrate and a second substrate joined in a bonding region, wherein the first substrate comprises a first Peak Force Tensile Strength and the second Peak Force Tensile Strength. The first Peak Force Tensile Strength is greater than or equal to the second Peak Force Tensile Strength. The bonding region has a Bond Density of about 10% to about 22%; and a Composite Tensile Strength at Peak Force that is within about 15% of the second Peak Force Tensile Strength.
