For some plastics and composites, the internal stresses of production may be reduced or eliminated by____, which consists of prolonged heating of the plastics part at a temperature lower than the molding temperature.
A) burnishing
B) milling
C) annealing
D) flame polishing

Question

Quizplus · Accepted Answer

Annealing is the process used to reduce or eliminate internal stresses in plastics and composites by heating the material at a temperature lower than the molding temperature for an extended period. This process helps in improving the material's dimensional stability and mechanical properties.
