Rob,

Excellent educational post. You said in your initial post:
Quote:
Added to these thousands of strings is a fiberglass mesh known as scrim. This adds toughness and stability. added to that are thrmoplastic resins that bond all the materials together when molded. graphite in this configuration has all it's strength along it's length. it has NO strength across it's grain.
Would you elaborate on "hoop strength" and how it contributes to the performance of a rod? Is "hoop strength" what you mean by "strength across its grain?" Does "scrim" provide all the "hoop strength" in a rod or is some additional method employed by various manufacturers?

Thanks in advance.
