Process for localization of a long-member profile that is inserted between fibrous support preforms that are assembled for forming a composite-material part
View Patent ↗An assembly of fibrous support preforms that makes it possible to obtain a composite-material part that includes a space ( 30 ) that originates from the assembly in which a long-member profile ( 32 ) of organic or inorganic fibers is housed and whose purpose is to fill the space ( 30 ), is characterized in that the long-member profile includes at least one metal fiber that extends over the entire length of the profile ( 32 ) so as to ensure the function of a marker that can be detected by detection element ( 38 ) that emit waves that can be modified by the marker ( 36 ).
1. Assembly of fibrous support preforms that makes it possible to obtain a composite-material part that comprises a space ( 30 ) that originates from said assembly in which a long-member profile ( 32 ) of organic or inorganic fibers is housed and whose purpose is to fill said space ( 30 ), characterized in that the long-member profile comprises approximately 20% metal fibers that extend over the entire length of said profile ( 32 ) so as to ensure the function of a marker that can be detected by detection means ( 38 ) that emit waves that can be modified by said marker ( 36 ).
2. Assembly of fibrous support preforms according to claim 1 , wherein the long-member profile comprises support fibers and the approximately 20% metal fibers are plaited, braided, or stranded.
3. Assembly of fibrous support preforms according to claim 1 , wherein the long-member profile comprises approximately 20% bronze fibers that extend over the entire length of said profile.
4. Process for localization of a long-member profile of fibers ( 32 ) that is provided to be housed in a space ( 30 ) that originates from the assembly of fibrous support preforms, whereby said assembly of fibrous support preforms makes it possible to obtain a composite-material part, and whereby said long-member profile of fibers ( 32 ) comprises support fibers, wherein the long-member profile of fibers ( 32 ) comprises approximately 20% metal fibers ( 36 ) that extend over the length of the long-member profile of fibers ( 32 ) and in moving—to the outside of the preforms—detection means ( 38 ) that emit waves that can be modified by said metal fibers ( 36 ).
5. Process for localization of a long-member profile of fibers according to claim 4 , wherein the long-member profile of fibers ( 32 ) comprises approximately 20% bronze fibers that extend over the entire length of said profile.
6. Process for localization of a long-member profile of fibers according to claim 4 , comprising using an ultrasonic sensor ( 38 ) for localizing said profile.
7. Process for localization of a long-member profile of fibers according to claim 6 , wherein the signal that is emitted by the ultrasonic sensor ( 38 ) has a frequency that varies from 5 to 10 MHz.
