Helicon Wants to Make Carbon Fiber Like Steel
The LA startup raised $16M to automate composite manufacturing — cutting lead times from six months to two weeks.

Carbon fiber is everywhere in the brochures and nowhere near the factory floor. The material that stiffens Formula 1 chassis and fighter jet fuselages still gets made largely by hand — sheets cut, laid, and cured by human workers in processes that can stretch six months from order to part. Helicon Industries, a Los Angeles startup, thinks that is about to change. The company emerged from stealth this week with $16 million in seed funding, led by AlleyCorp, and a pitch to compress composite manufacturing lead times to two weeks. [1]
Helicon is building automated manufacturing systems designed to move carbon fiber composites into high-volume production — the kind of scale measured in hundreds of thousands of parts, not hundreds. [1] The company is relocating to a 36,000 sq. ft. space in Torrance, California, and designing every process and piece of equipment around robots rather than retrofitting automation into a legacy workflow. [1]
The problem Helicon is attacking is structural. "Composite manufacturing is still a very manual process, it's difficult to automate, especially the manipulation of flexible materials like carbon-fiber textiles," said co-founder and CTO Edmundo Sanz-Gadea. [1] Traditional production begins with a mold, into which workers place carbon fiber material — either prepreg, which contains resin already, or dry fiber that gets resin added through vacuum infusion or resin transfer molding. [1]
A new tier of customers is less patient. "The challenge is figuring out how to manufacture lightweight, high-performance structures in the hundreds of thousands rather than the hundreds," Sanz-Gadea said. [1] Most of those companies currently buy flat carbon-fiber sheets from overseas suppliers, cut them to shape, and assemble the result with fasteners — an approach Sanz-Gadea describes as "a very inefficient way to build a structure." [1]
Helicon's answer is to redesign the process around what robots can reliably do. The company targets cycle times under 15 minutes, compared with hours for traditional layup and autoclave curing. [1] Its systems are designed so a robot can pick material, place it, extract the finished part, and handle downstream steps like trimming and quality inspection in a single cell. [1] "For robotics, we don't need massive industrial arms," Sanz-Gadea said. "The important part is designing the whole cell around repeatability and speed." [1]
The robotics market itself is among Helicon's target customers. "Most robotic systems today are made from aluminum, and our materials offer higher stiffness at 40% lower weight," Sanz-Gadea noted. [1] That weight reduction translates directly into longer battery life, smaller actuators, or higher payload capacity — meaningful gains as humanoid and mobile robot platforms move toward mass production. [1]
[2] "He understood what we were trying to build immediately," Sanz-Gadea said. "He flew from New York to San Francisco the next day to meet us." [1]
Carbon fiber sits at a similar inflection: the performance case is settled, the production story is not. Whether a seed-stage startup can close that gap is a different question, but the direction of travel is clear.
Helicon is now hiring across mechanical and structural engineering, software, robotics, and operations. [1] The founding vision, as Sanz-Gadea frames it, is not a single product line but "the manufacturing capacity to produce advanced composites at a real industrial scale" — starting in Torrance, with a much longer runway in mind.
