40 Resin Matrix are two-part systems consisting of. A A Resin and A Catalyst. B A filler and A Catalyst. C A Resin and A filler.

44 Is the time which the product is still good in an unopened container. A Pot life or working life. B Shelf life. C Curing time.

46 If too much resin is used, the part is called. A Much resin. B Resin rich. C Too rich.

47 What could happen to the fibers if too much pressure is applied when using a brush or squeegee?. A The fibers could pull mixed, changing the strength characteristic of the fabric. B The fibers could pull apart, changing the wovens characteristic of the fabric. C The fibers could pull apart, changing the strength characteristic of the fabric.

49 Pre-preg fabrics are manufactured to. A Eliminate the mixing, applying and worry about whether the proper mix ratio was used or if the proper amount of resin was applied. B Eliminate the mixing, applying and worry about whether the proper mix ratio was used or if the proper amount of catalyst was applied. C Eliminate the work, applying and worry about whether the proper mix ratio was used.

50 Pre-preg fabrics are manufactured by. A dipping the woven fabric into a resin solution. B dipping the strands fabric on a resin solution. C dipping the threads fabric inside a resin solution.

51 The terrn "out of freezer Iffe" is. A The time that the material is actually out of the freezer and is being cut or transported. B The time which the product is still good in an unopened container. C The time that the mixed resins will be workable.

What are Microballooms?. A are small spheres of plastic or glass. B are small spheres of graphite or glass. C are small spheres of kevlar or glass.

The big difference between composites and aluminum lies in. A The Assembly time. B Fabrication time. C Material cots.

63 Which method is effective when used on large contoured surfaces which cannot be clamped?. A Clecos. B Shot Bags. C Vacuum Bagging.

65 What is bleeder material?. A An nonabsorbent material that is either placed around the edges or on top of the repair to absorb the excess matrix. B An absorbent material that is either placed around the edges or on top of the repair to absorb the excess matrix. C An sealed material that is either placed around the edges or on top of the repair to absorb the excess matrix.

66 What is breather material i?. A An absorbent material that is either placed around the edges or on top of the repair to absorb the excess matrix. B Placed to one side of the repair to allow air to flow through it and up through the vacuum valve. C Placed to upper of the repair to allow air to flow through it and up through the repair.
