Sheet Molded Compound (SMC) panels are correctly repaired using which bonding method?

Explanation:
Adhesive bonding is the correct method because Sheet Molded Compound (SMC) is a glass fiber–reinforced thermoset plastic that cannot be welded or soldered without damaging the resin or fibers. Riveting can introduce stress concentrations and holes that compromise the panel, and welding would burn or weaken the material. An adhesive bond provides a strong, uniform connection that distributes loads across the repaired area and preserves the structural integrity of the SMC. Proper surface preparation and using a suitable structural adhesive (with correct cure time and clamping) are essential for a durable repair.
