What they make
According to their website, CTMI has produced technical textiles since 1886, originally as a Lyon-region silk weaver, and converted its looms to fiberglass, aramid, carbon and quartz weaving as the silk market declined in the 1980s. Today the company, based in La Sône, France and now part of the Chomarat group, runs two production sites totaling 8,600 square meters and offers four connected processes: 2D and 3D weaving (fabrics up to 170 cm wide, 60-600 g/m2, including a dedicated clean room for quartz), weft and warp knitting (warp fabrics up to 320 cm wide) in quartz, glass, PEEK and PEI, hot-melt pre-impregnation with proprietary epoxy, cyanate-ester and tooling resin systems in yarn and fabric form, and dry preform manufacturing (powdering, heat setting, sewing, in-house RTM epoxy resin) from 3D-woven carbon fabrics. Roughly half of revenue comes from aeronautics, with industry and defense each contributing a quarter. Production is ISO 9001:2019 certified, and the site sources 45% of its electricity from hydroelectric power.
- 2D and 3D weaving of technical fibers (carbon, quartz, glass E/S2, aramid, PEI, SiC, Dyneema, basalt) in widths up to 170 cm and weights from 60 to 600 g/m2, with a dedicated clean room for quartz fabrics
- Weft and warp knitting, including warp-knitted fabrics up to 320 cm wide, in quartz, glass, PEEK, PEI and comingled yarns
- Hot-melt pre-impregnation using proprietary epoxy (120C/180C/230C), cyanate-ester and low-cure tooling resin systems, supplied as yarn or fabric pre-preg, including fire-retardant and low-permittivity space/radome grades
- Dry preform manufacturing from 3D-woven carbon and carbon/PEI fabrics, with powdering, binder application, heat setting and sewing, plus an in-house RTM epoxy resin system
- Two production sites in La Sône, France totaling 8,600 square meters, certified ISO 9001:2019
