Carbon Fiber Materials for O&P
Carbon fiber materials for orthotics and prosthetics comprise textiles, braided sleeves and bands used to laminate sockets and orthoses. Where more than one fiber orientation is required, a fabric combining 0 and 90 degree orientations is useful; woven fabrics are produced by interlacing warp and weft fibers in a regular weave style.
- Carbon fiber braided sleeves, diameters 25 to 180 mm, 35 to 205 g/m2
- Carbon fiber textiles C201 and C206, twill 2×2, fiber orientation 0/90 degrees, width 1 m, high strength carbon T700 12K
- Carbon fiber band, code 8.001.03.BCF100, 8000 dtex or equivalent
- PREPREG CBX textile at plus or minus 45 degrees, pre-impregnated with resin
- T300 3K mechanical properties: tensile strength 360, tensile modulus 23.5, elongation at break 1.50, density 1.76
- Prepreg advantages: constant resin-to-fiber ratio, easier lamination, better control of composite properties, laminate homogeneity and process repeatability
- Prepreg is B-stage material and requires cold storage; curing usually needs an oven or autoclave
- Textile properties certified to UNI EN 12127, UNI EN ISO 5084 and UNI EN 1049-2

PREPREG is a big advantage for the production because is possible to have the same ratio/percentage between resin and fibers in the prepreg, easy to laminate, and more efficient control of the properties of the composite reliability and homogeneity of the laminate and process repeatability.
