Tube - Round - INFINITubeV - High Modulus - Plain Weave material question

[Brian]

I am trying to figure out which prepreg plain weave this tube uses. It states high modulus but there are no "high modulus" prepregs listed on rock wests website. Thanks

Hi Brian. Welcome to the forum. 
This is a great question. For tubes that have fabric on them, we use different pattern fabrics to visually discern which tubes are standard, intermediate , or high modulus fabricated tubes. The entirety of the tubes are fabricated from unidirectional fibers, but the outer fabric layer (which is always standard modulus) will dictate which modulus fiber the tube is constructed from. If you look through our catalog, you’ll see a pattern emerge that you may not have noticed before. 
once a material is cured, it is very difficult to determine which fiber it was made from. This is away for us to visually keep them organized.
