Passage:
During composite aircraft repairs, technicians seal an airtight vacuum bag over layered carbon fiber plies before curing them under heat. A continuous vacuum draws out trapped air and excess resin through a porous release film into an absorbent bleeder cloth. If vacuum pressure drops during the thermal cycle, air bubbles remain trapped between plies, forming microscopic internal voids that drastically diminish the panel's load-bearing capacity.
Based on the passage, evaluate whether the following statement is True or False:
Maintaining continuous vacuum pressure during the curing cycle is primarily intended to preserve structural integrity by preventing internal voids, rather than accelerating the heating process.
Cevap: Cevap
Cevap
True
The correct evaluation is True. The passage details that vacuum pressure extracts air bubbles that would otherwise cause microscopic voids and degrade the panel's load-bearing strength. This logically implies that the system's core purpose is ensuring structural integrity rather than expediting the heating cycle.
