Engineering Why is it expensive to recycle composite materials?

Click For Summary
Composite materials are challenging to recycle due to their complex structure, which often combines multiple materials that are difficult to separate. The recycling process requires specialized technology and methods, increasing costs significantly. Additionally, the market demand for recycled composites is limited, making the economic viability of recycling less attractive. The lack of established recycling infrastructure further complicates the situation. Understanding the composition and properties of these materials is crucial for developing effective recycling solutions.

I have read a document where it says that composite materials are expensive to recycle but did not explain why. However, I am searching and find only a few papers and answers.
 
Physics news on Phys.org
Do you know what composite means? What implication does this have for recycling?
 
Thread 'Why wasn’t gravity included in the potential energy for this problem?'
I’m looking at the attached vibration problem. The solution in the manual includes the spring potential energy but does NOT include the gravitational potential energy of the hanging mass. Can someone explain why gravitational potential energy is not included when deriving the equation of motion? I tried asking ChatGPT but kept going in circles and couldn't figure out. Thanks!
