SUMMARY

Polycarbonate is identified as a superior material for durable CD cases due to its high fracture toughness and shatter resistance. It is recommended for applications requiring transparency and durability, particularly in environments where impact resistance is crucial. The discussion emphasizes the need for materials that are cost-effective, with polycarbonate being a viable option as it is not more than twice the cost of polystyrene while offering better mechanical properties.

PREREQUISITES
  • Understanding of material properties, specifically fracture toughness and Young's modulus.
  • Familiarity with polycarbonate and polystyrene as materials.
  • Knowledge of cost analysis in material selection.
  • Basic principles of impact resistance in materials.
NEXT STEPS
  • Research the specific fracture toughness values of polycarbonate compared to polystyrene.
  • Explore the manufacturing processes for polycarbonate CD cases.
  • Investigate the cost implications of using polycarbonate versus polystyrene in production.
  • Learn about the applications of polycarbonate in other industries, such as eyewear and safety equipment.
USEFUL FOR

Material scientists, product designers, and manufacturers looking to optimize the durability and cost-effectiveness of packaging solutions, particularly in the context of CD cases.

Polycarbonate fracture toughness?

I am doing a project in which I have to make a cd case out of a material which is transparent, has a young's modulus not too different to polystyrene, can't cost more than twice polystyrene and has a fracture toughness better than polystyrene!

Polycarbonate looks good so far but I can't find the fracture toughness of it anywhere.

Please Help...
It's due tomorrow!

Thanks!

Polycarbonate is highly resistant to fracture, which is why I always recommended it for kids' lenses. You can find shatter-resistance information if you look around.
