In the composites industry, use of polyetheretherketone (PEEK) has recently experienced an uptick in thermostamped aircraft fuselage clips and brackets made from preconsolidated blanks with woven and/or unidirectional reinforcements (see “Thermoplastic composites "clip" time, labor on small but crucial parts" and "Inside a thermoplastic composites hotbed," under "Editor's Picks,” at top right). But those who use and those who make the blanks recognize their limitations.

Validation of 80-100% tensile strength and comparability to injection molding via Voxelfill extrusion process was achieved through plastic and fiber-filled test series.

During this CW Tech Days event, sponsored by Composites One, experts will offer presentations to review and evaluate the composite materials, processes and applications that should and will be considered for use in the infrastructure and construction markets.

Because the substrate blanks are multi-ply composite layups, they are easily tailored for specific properties and/or load handling. For example, Tri-Mack has the ability to place and orient UD tapes in the blanks, using in-house automated molding cells. In fact, the company’s Advanced Composites Center, adjacent to its main plant, was designed specifically to enable automated layup, consolidation and thermoforming of composite materials in conjunction with its legacy injection molding capabilities, to replace both metals and thermoset composites in aerospace applications.

The composites industry plays a crucial role in developing lightweight and durable materials for a range of applications, including those critical to national defense. One key focus area is the development of advanced structural materials and manufacturing technologies that support next-generation space, missile and aircraft systems for the U.S. Department of Defense (DOD). ARC Technologies LLC (ARC), a division of Hexcel Corporation, based in Amesbury, Massachusetts, is a provider of advanced composites structures, specialty materials and other unique products that provide the U.S. Department of Defense with advanced capabilities to protect service members while in harm’s way. This team’s specialty is to understand a specific need from a program office, PEO, platform manufacturer or other offices within the DOD. With that understanding, the team can design a solution, develop a prototype for test and evaluation, perform extensive in-house testing — including electromagnetic, environmental and structural testing — and then partner with the customer through platform evaluation. The Hexcel Amesbury division has a team of engineers on staff, including mechanical, chemical, electrical and research and development specialists that can provide design, testing and manufacturing capabilities to service customer requirements from concept through production. This presentation will illustrate capabilities in advanced composites and other specialty materials structures, focusing on the Hexcel Amesbury team's niche in electromagnetic signature reduction and other unique capabilities.

To demonstrate the process, Tri-Mack needed a part that would deliver the message. “There are so many brackets used in aerospace,” says Kneath, “and we’ve made a simple bracket with thermoplastic composites, so we decided to design a complex bracket shape that would also bear significant load.” The design is loaded in three axes and incorporates four mounting points that rely on co-molded metal inserts in the PEEK overmold, the latter a typical feature of Tri-Mack’s unreinforced thermoplastic brackets. “We load the aerospace-grade, carbon fiber-reinforced PAEK substrate and four metal inserts into a standard injection mold,” describes Kneath. “We use a standard process to inject VICTREX PEEK 150CA30” — 30% carbon fiber-reinforced compound — “over the substrate, and minutes later, we have an integrated assembly that marries the performance of PEEK composites with the cost efficiency of injection molding.” (See photo at left.) Initial testing shows a very robust bond between the PAEK and PEEK matrices. “This will build confidence in the engineering community as they start to design parts exploiting this technology,” Kneath asserts.

“Our idea was to combine the chemical resistance and moldability of thermoplastics with the high performance and light weight of composites,” says Tri-Mack director of sales Tom Kneath. “Only then can thermoplastic composites penetrate into new applications where plastic alone cannot go because of the mechanical properties required.” But the organosheet process is not without issues. Traditional steps include preheating a preconsolidated thermoplastic laminate to remelt temperature, transfer to an open injection mold, closing the mold to thermoform the blank to shape and then injection overmolding with fiber-filled melt to provide the finished three-dimensional surface. As presented by Alan Wood at the 2nd International Conference and Exhibition on Thermoplastic Composites (ITHEC 2014, Oct. 27-28, Bremen, Germany), Victrex had to work through an array of issues, including support of the substrate during preheating, control of fiber orientation during forming, potential restriction to a uniform blank thickness to ensure matrix melting, and the development of polymers that would indeed fuse together during overmolding.

“The design flexibility is huge,” he adds, noting the same bracket made with forged metal would require a significant amount of machining. “That’s easy to beat with a 2-3 minute injection molding.” Kneath concedes there is a tooling cost, but says the payback is usually pretty quick. “Most aerospace companies will say they don’t have the volumes for injection molding, but we’ve been injection molding aerospace parts for 40 years, and know how to design tooling that balances cash and performance requirements.”

“The industry needed overmolding,” he explains, like the organosheet process now common with polyamides and polypropylene in the automotive industry (see “CAMISMA's car seat back: Hybrid composite for high volume,” under "Editor's Pick's"). Aerospace parts manufacturer Tri-Mack (Bristol, RI, US) already had begun exploring this type of PEEK processing as part of its thermoplastic composites development. The two have now demonstrated a new hybrid molding process for PEEK that uses a lower temperature continuously-reinforced Victrex polyaryletherketone (PAEK) composite as a substrate, overmolded with short fiber-reinforced PEEK, to produce a high-performance loaded bracket that is as much as 60% lighter than comparable metal components.

And it’s not just cellulose that can be used – the team is also exploring how so-called non-tree-based fibers could work. “In addition to virgin fiber, we can incorporate recycled content and, in some cases, non-tree-based fibers for added properties,” he told us.

Overmolding offers aerocomposites molders the advantages inherent in both molding “worlds”: Complex aerospace thermoset composites can provide desired functionality and strength at low weight but “require hand layup and autoclave processing, resulting in parts production that takes hours to days,” comments Kneath.

So how does DMF compare to cardboard production on emissions, for example? “This solution is quite different to cardstock,” Perrotta said. “We can produce a myriad of sizes and shapes not possible in either cardstock or wet-molded processes today.

In contrast, injection molding of neat thermoplastics produces complex components in minutes, but limits the molder’s ability to optimize part functionality. “What’s great about this hybrid process,” Kneath points out, “is that you can put the material where you need it, vs. standard injection molding, where you can’t really selectively reinforce parts easily.”

“We are designing for standard kerbside collection and expect the dustcart pressure to easily and quickly separate the liner from the outer layer," Perrotta continued. “In addition, since a liner is being employed, the pulp is of a higher grade than alternatives,” he claimed. “The liner houses the product and any chemistry of the product keeping the pulp high grade.”

“We could mold PEEK over PEEK, but it doesn’t fuse together,” says Herr. Fusion of the matrices requires a substrate with a lower melt temperature than the overmold. “If you don’t fuse the two, you don’t consolidate the part,” Herr points out. “So, we needed a low-temperature processing PAEK that has PEEK properties.” Think of PAEK as the polymer family — Victrex can make different formulations, each with a specific molecular weight, melt temperature and Tg — with PEEK being one species. Thus, Victrex developed the PAEK A250 polymer, with a melt temperature of 305°C (see Table 1, at left). “We have enabled not only overmolding with PEEK,” claims Herr, “but also the ability to achieve PEEK-type properties at processing temperatures similar to PPS or PEI with current equipment.”

“This is an enabling technology, offering so many opportunities beyond brackets,” says Kneath, adding that, given PEEK’s mechanical and elevated-temperature performance and chemical/corrosion resistance, there are few areas where it’s not a suitable solution. “We could be talking more complex housings or different types of panels with very thin, overmolded fiber-reinforced ribs.” Tri-Mack also sees opportunities in the process for imparting multi-functionality. “We have evaluated technologies that would add lightning strike protection (LSP) paths or EMI shielding. This is typically done with secondary coatings or by adding a metallic layer to the layup,”  Kneath says, but Tri-Mack is now exploring how to do this via the compounds used in the hybrid processing.
