What is typically done to limit warpage in bonded repairs of flat surfaces?

To limit warpage in bonded repairs of flat surfaces, applying pressure uniformly is often a critical practice. Uniform pressure ensures that the adhesive cures evenly across the entire surface area, thereby preventing uneven stress distribution that could lead to warping. If areas of the bond cure at different rates or with different tension, it can introduce warpage in the repair.

Incorporating short strips of fiberglass can provide reinforcement, but it does not specifically address the warpage that may occur due to uneven curing or pressure application. While alternating layers of materials can sometimes help with structural integrity, it does not inherently control the warpage that is often associated with adhesive bonds. Similarly, applying heat and cooling cycles might help in some applications to facilitate bonding but does not directly target the warpage prevention as effectively as uniformly applied pressure does.

Therefore, the best method to limit warpage in bonded repairs of flat surfaces is to ensure that pressure is applied uniformly across the repair, facilitating an even and stable bond.
