Excerpts of Q/A sessions from the tutorials

Question from today was "Are there any examples of these high performance glass materials?"

In response to the question raised in the presentation about Materials and Processing, Prof. Miravete informed that the electrical conductivity of carbon fibers ranges from 500 - 20,000 (ohm-cm)-1.

These are the most relevant references for the presentation on fibers, matrices and manufacturing:

1. Is a special process used to remove the reusable vacuum bags from the cured part to ensure the bags are not damaged, or are they sufficiently robust to allow them to be removed by hand?

Question from Armando Mete: “Could you please provide Elastic/Strength properties for AS4/3601-6, IM6/3501-6 used for the Abaqus Umat-MMF Examples?

Question #1: From Fulya Aktas: "Do you do any surface treatment to bind CNTs to resin?"
Answer: "In our research work we have used MWCNTs and have not applied any surface treatment."

During lecture 5 (April 28, 2009) - Test Methods, by Dr. Ran Kim, a participant asked for further examples of fracture toughened materials.. Dr. Kim sent the following response:
