Abstract
A tracer strand for the weaving of a composite material part reinforcement, the tracer strand including one or more carbon yarns twisted with one or more yarns of a material having a color contrasting with the color of the carbon yarns, the yarns being twisted together according to a twist included between 10 turns per meter and 80 turns per meter.
Claims10
A method for manufacturing a tracer strand for the weaving of a composite material part reinforcement, the method comprising twisting one or more carbon yarns with one or more yarns of a material having a color contrasting with the color of the carbon yarns, the yarns being twisted together according to a twisting rate comprised between 10 turns per meter and 40 turns per meter, wherein, during the twisting, a tension is applied to the one or more carbon yarns that is greater than a tension applied to the one or more yarns of a material having a color contrasting with the color of the carbon yarns,
- wherein the tracer strand is obtained by twisting three carbon yarns each having a count of 12K, with three glass yams each having a cross section equivalent to the cross section of a carbon yarn with a count of 12K, the twisting being accomplished according to a twisting rate of 20 turns per meter.
A tracer strand for weaving a composite material part reinforcement, the tracer strand comprising one or more carbon yarns twisted with one or more yarns of a material having a color contrasting with the color of the carbon fibers, the yarns being twisted together according to a twist comprised between 10 turns per meter and 40 turns per meter wherein, during the twisting, a tension is applied to the one or more carbon yarns that is greater than a tension applied to the one or more yarns of a material having a color contrasting with the color of the carbon yarns, wherein the tracer strand is obtained by twisting three carbon yarns each having a count of 12K, with three glass yams each having a cross section equivalent to the cross section of a carbon yarn with a count of 12K, the twisting being accomplished according to a twisting rate of 20 turns per meter.
