Fiber Composite Theory for Modeling Oriented Films Quiz

horizontal rule

  1. Fibrillation has been observed by many researchers who have studied oriented films.  In the model presented, we assumed an infinitely long fiber would suffice for predicting the mechanical behavior.  List three reasons why this may be acceptable.
  2. Now, list three reasons why the infinitely long fiber model may not be an acceptable model for oriented films.
  3. Discuss how slippage between the fiber and the matrix may occur and how it can be mathematically incorporated into a model.  What would be evidence of slippage occurring between the fibers and the matrix.
  4. In oriented films, how does the operating temperature affect the drawability of the film.
  5. How does the changing the draw ratio affect the mechanical properties of the film?
