Tucson: Advanced Ceramics Manufacturing Profile

Firm’s ceramics discover myriad uses in aerospace

Water-soluble ceramic: It’s hard as rock, dissolves in wa­ter, and hopefully turns into money.

When you look up “coun­­terintuitive,” there should be a picture of Robert Doucette, production manager of Ad­vanced Ceramics Manufactur­ing, making one of the compa­ny’s ceramic forms — known as a mandrel in the tool and die business — disappear in a gen­tle stream from a garden hose.

These water-soluble ce­ramics, which can be turned into a drain-safe soup, are the backbone of this local compa­ny’s business.

“It’s virtually food grade; you can wash it down the drain,” says ACM president Steve Turcotte, watching the demonstration on ACM’s loading dock in the San Xavier Development Authority’s Hi:kdañ Business Park.

Advanced Ceramics Manu­facturing makes a variety of products, mainly for aerospace manufacturing — from parts for the latest superliners and tiny unmanned aircraft to re­verse- engineered ductwork for 40-year-old jet fighters and other “legacy” aircraft parts.

The company was founded in 2001 as a joint venture be­tween Advanced Ceramics Re­search, a materials developer and drone maker started in 1989 by two University of Ari­zona engineers, and the San Xavier Development Authori­ty.

After Advanced Ceramics Research was acquired in June by defense giant BAE Systems Inc. in a $14.7 million stock deal, Advanced Ceramics Manufacturing was sold to the San Xavier Develop­ment Authority, an arm of the Tohono O’odham Nation, and founders Anthony Mulligan and Mark Angier.

Making cleaner parts

The bulk of ACM’s ceramics work is for aircraft —from the latest enormous super jetliners and small UAVs (Unmanned Aerial Vehicles) to decades-old jet fighters and helicopters.

Carl Aune, sales and mar­keting manager, shows a plas­ter form for an F-15 part, possi­bly a piece of ductwork. The plane was designed in the early 1 970 s.

Making new parts the old way, using plaster forms, is troublesome. The plaster has to be destroyed after the duct is formed over it. That can leave debris inside and busting out the cast from the compound curves of a complex part is not only difficult, but can damage the part.

A water-soluble ceramic mandrel, however, can be cleanly and safely dissolved with water.

ACM’s environ­mentally friendly ce­ramic mandrels are no small thing, especially near Tucson Interna­tional Airport, atop an aquifer that was contaminated with carcinogenic indus­trial solvents used by the air­craft industry nearby.

The process is no small thing for the industry, either. Making aircraft parts, and the forms used to make such parts, requires precision and reliabil­ity.

Turcotte and Aune say they hope to do more work for modern aircraft, including Boeing’s new 787 Dreamliner.

That may include helping to make thousands of holes in the Dreamliner. One of their prod­ucts getting interest is a ce­ramic drill bit that can stand up to the tough carbon fiber used in the Dreamliner and most of the latest generation of air­craft.

Turcotte says the “sand­wich” of carbon fiber, alu­minum and titanium used to make the fuselage of the Dreamliner and other new air­craft is so tough that it can re­quire drill-bit changes on each of the hundreds of thousands of holes that have to be drilled in the material on a large plane. That’s expensive and time consuming. Turcotte says ACM’s ceramic drill bit is up to the task.

And there is work on less glamorous, but equally impor­tant, aircraft. ACM is making ceramic mandrels for air ducts on the newest version of the U.S. Marine Corps CH-53 Heavy-Lift helicopter.

It also makes Fiberglas body parts for UAVs made by BAE Systems.

As with most aerospace manufacturing or repair opera­tions, there is a fundamental, but unspoken, principle. Tur­cotte, a former Navy flier, says if anybody were to put it on a workplace plaque it would read something like: “Let us try our best to break things here and now — on the ground.”

Every aircraft part has its own 24/7 reality show. Every­thing that happens to it is all on record in mind-numbing de­tail, a pile of paperwork that follows each aircraft and each of its parts from manufacture to the crusher.

Branching out with R&D

Not everything ACM does involves aircraft, or even ce­ramics. It sells jar mills — much like rock tumblers used in lap­idary work — that continuously rotate plastic jars on horizontal rollers to polish parts inside the ja rs.

Turcotte says ACM today is split about half and half be­tween research and production. And while the bulk of the company’s work is aerospace related, it occasionally veers off into new territory, such as a “tree spike” that gets its energy from its host tree (or saguaro) that could be used to power mi­crocircuits to keep an eye on what’s going on nearby, or just report on the tree’s health.

The project was originally funded by the National Science Foundation and has continued funding from Homeland Secu­rity, Aune said. Besides keeping an eye on the border, the tree spike could even be adapted for use in pre­venting saguaro cactus poach­ing, with tree-powered radio­frequency identification tags set to report any movements to authorities, Turcotte said.

Ideas and work that come out of the research and develop­ment section, headed up by Zachary Wing, ACM science and technology director, is like­ly where the company’s future lies, says Turcotte.

Wing says ceramics research has some exciting potential, such as transparency. He shows a piece of a special ceramic ma­terial that is translucent. Com­bining ceramic toughness — it is used in armor, after all — with transparency would have obvious defense applications.

Advanced materials are where it’s at and where it’s go­ing in aerospace, Turcotte says.

“The Boeing 787 (Dreamlin­er) is over 50 percent composite material,” says Turcotte. “The 777 (Boeing’s last airliner) was only 12 percent.”
