Why does crosslinking increase the resistance of golf ball covers to cuts?
 
  What will be an ideal response?

Question 2

A submarine driveshaft was made of epoxy and carbon fibers by filament winding. Indicate two reasons why composites have unique and excellent properties for this application. The part was cured in an oven at 250F (120C). On close examination, the shaft was found to spin irregularly and to cause vibrations. Identify four possible causes of this problem and four possible solutions.
 
  What will be an ideal response?

Question 3

Define a gel coat and give three reasons for its use.
 
  What will be an ideal response?

Question 4

Answer to Question 1

Crosslinking increases the strength of the material, overcomes the inadequacies in knitting the material.

Answer to Question 2

Two advantages: an anisotropic material, easier to design a part in composites that will withstand the torsional forces placed upon it.

Four possible causes: unbalanced fiber placement, uneven weight distribution, inadequate strength for the forces applied, insufficient material

Answer to Question 3

A gel coat is a coating of resin that is sprayed or brushed into a mold prior to any placement of fiber reinforcement. The gel coat gives a smooth, fiber free surface. The gel coat can be pigmented, thus eliminating the need for painting the part.

The gel coat can have additives, such as UV-stabilizers and anti-oxidants that help protect the part from environmental exposure.

Answer to Question 4

Reduction in the total number of electrons passing through the chamber.
