RE: Want More Accuracy? Pick Carbon Tech Arrows
Len,
As I’m reading I find that you touched on every comment except wall thickness as compared to strength. Can you please educate me in this area? This is my experience:
I have been in a line of work where a small part of my job was to make composite repairs and that experience has also been involved with flight control surfaces on corporate jets. We add a layer, then add the resin/3M 9309 adhesive. Add another layer and more resin, etc. After the repair is done we hook up a vacuum system to the repaired area to suck down all the layers and to remove any air gaps/delamination pockets for pure strength. What I have learned is that the more layers the stronger the repair. If you don’t add multiple layers of glass/carbon fiber and try and fill the void/contour with just the resin/3M 9309, all you get is a good looking repair, but one that is brittle.
Now when I study arrow wall thickness, it appears that my Carbon Tech Manual shows that the stiffer spine arrows have more layers. As an example comparing apples to apples in spine: Your Rhinos at .300 spine should have 7 layers. My Whitetails at .300 spine should have 6 layers. Your .300 spine Rhino wall thickness is around .069 and mine should be around .059. Your Rhinos are stronger than my Whitetails due to the increase in wall thickness, right? As you go down in spine strength, the layers are less, thus a weaker spine. Their lighter spined target arrows only have 4-5 layers, thus a thinner wall diameter. On the other hand, every layer added makes the wall thickness greater, therefore stronger in my mind. How is it that I have been told that wall thickness has nothing to do with strength when it appears they go hand in hand? My motives for this question are not to attempt to drive my wonderful debater to his knees; I’m looking to understand something that I already thought I had figured out.[:@]
