How is splicing of thermoset materials commonly done?

The splicing of thermoset materials is commonly performed by lapping and using additional adhesive due to the nature of thermoset polymers. Thermoset materials, once cured, cannot be remelted or reshaped, which means that traditional methods like welding are not applicable. Instead, lapping, which involves overlapping two pieces of material, provides a larger surface area for bonding.

Using additional adhesive ensures a strong and durable bond, as thermoset materials benefit from good adhesive properties that can enhance the performance of the joint. This technique not only allows for effective splicing but also accommodates the different mechanical properties and the chemical stability of thermosets, making it a reliable method in applications where strength and integrity of the splice are critical.
