Cotton Sleeve

Cotton sleeves are suitable for the production of profiles of any kind, as spars or other hollow constructions, whereby a suitable application process ensures that the force-absorbing reinforcing fibre of the cotton sleeve is free of air bubbles, all-over and seamless - thus without loss of strength - even around the edge of the shaping core and is sufficiently impregnated with the resin system used. For high torsional or shear strength, a 45° angle is optimal. The diameter of the braided sleeve can be changed by stretching or compressing, but the fibre angle should ideally be between 30° and 60°. Reinforcement in the 0° direction can be achieved with so-called UD threads, which are also braided in. Another material can certainly be used for this purpose.
As a natural fibre, cotton sleeves are 100% recyclable, have a very low weight and the elastic properties of the cotton fibre result in excellent impact strength.
Cotton sleeves can be processed into natural fibre composites by embedding them in epoxy or polyester matrices.
