2
Q
What are the two main effects of fibers on composites properties?
A
Decreasing the density and increasing the stiffness
3
Q
When it comes to glass reinforced plastics, when do we expect to have less anisotropy in tensile properties? (more uniform tensile properties in all directions)
A
Random orientation of glass fibers
4
Q
WHat is the main purpose of having cleanrooms for the production of electronic parts?
A
To limit the dust levels since they can ruin the whole circuit.
5
Q
