I need to buy 100% carbon fibre tubes 26mm inner diam x 31mm outer diam x 110 cm long to built custom made spearguns . 

I too am looking at Pultruded vs. Wrapped.  Yet for me, this is no speargun.  It is for Foam Fighting, a full contact full force game that uses weapons made from foam, but not nerf foam, we would break and blow out those weapons in seconds. We use a mixture of 2, 4 lb and volara foam to put around a 'core' which is the backbone of the weapon. No core = no strength.  PVC cracks and is dangerous because of the way it shatters and leaves jagged edges.  Steel and wood is too heavy and leads to monster strikes and can lead to unnecessary injuries.   We have used fiberglass in the past, and now carbon fiber rods are the new norm as they are strong, fast, and ultimately safe. I was just looking to purchase some rods for making some foam weapons.  What would be best for the type of force of say, axe swings, sword swings and the like?  Pultruded or Wrapped? 

Thanks!
