: I would like to find out if there is such a thing as a, UT transducer, that is able to take thickness readings of FRP pipe material. (* FRP = Fiber Reinforced Plastic *)
: I don't think that a transducer would be able to use sound to obtain a thickness reading due to the amout of glass fiber in the material. But then again, I could be completely wrong and need to be shown the light.

Over the years I have had a number of experiences with FRP. Krautkramer once had a thickness gauge the CL202F which uses the ZIP zero interface probe, it is now no longer available. This probe works well as it is a 0.5MHz probe with a special delay block to reduce the interface echo, ( as the name implies). Details can be found on the KK website about ZIP probes.
Recently we have been using the piezo-composite probes for testing FRP pipe and rubber conveyor belt with great success. Try the K1SC, MSEK2 and MK1S
