This limitation can increase labor costs and extend project timelines, particularly in large-scale industrial setups.
Limited Mechanical Strength
Not suitable for applications requiring high structural integrity, often necessitating additional support or reinforcement.
Rigid graphite felt lacks the mechanical strength needed for applications demanding high structural integrity. While it excels in thermal insulation and chemical resistance, its limited load-bearing capacity restricts its use in environments with significant mechanical loads or vibrations.
In the metallurgical industry, rigid graphite felt is extensively used in furnace linings. However, additional support structures are often required to maintain its position and effectiveness under operational conditions.
For instance, in aerospace applications, rigid graphite felt provides excellent thermal protection but must be reinforced with other materials to withstand mechanical stresses during flight. Similarly, in advanced battery systems, it serves as a key insulating component but relies on external frameworks to ensure stability.
This limitation underscores the importance of evaluating application requirements before selecting rigid graphite felt. While it offers unmatched performance in specific scenarios, its mechanical constraints may necessitate alternative solutions or supplementary materials in certain industrial contexts.
Application Constraints
Performance may vary depending on specific industrial conditions, and it is not ideal for environments with high mechanical loads or vibrations.
