在為即將進(jìn)行的飛行測(cè)試做準(zhǔn)備時(shí)，Scion需要為Vixen直升機(jī)生產(chǎn)線建立外部碳燃料箱，而保持精確性是關(guān)鍵。在直接工具應(yīng)用中使用了黑色Corintho 800，一旦板被粘合、數(shù)控加工和密封，Hexcel M35-4環(huán)氧預(yù)浸料就被鋪在工具上，在50 PSI/180°F的高壓釜中固化16小時(shí)。
多年來，用可供選擇的工具制造低成本、高精度的原型幾乎是不可能的。對(duì)于這種類型的應(yīng)用程序，金屬工具是笨重的，昂貴的，并且在10次中超過9次。自然的解決方案是模具板，但傳統(tǒng)上，熱膨脹的協(xié)同效率已被證明難以維持對(duì)高精度原型的必要容忍，“Scion航空公司的所有者吉姆·桑普森說。“對(duì)Scion來說，黑色Corintho 800正是這方面的佳選擇，因?yàn)樗浅７€(wěn)定，熱膨脹系數(shù)極低，并且大大加快了我們的進(jìn)程，從而節(jié)省了時(shí)間和金錢。”這確實(shí)改變了我們的工作方法，使我們?cè)趫?bào)價(jià)過程中更具競(jìng)爭(zhēng)力。“
Vixen直升機(jī)系列由無人/可選的載人變體組成，目前正在接受Scion航空公司與Safran合作進(jìn)行的飛行測(cè)試，終用作海上巡邏艇(OPV)和美國(guó)海軍、美國(guó)陸軍和民用的其他應(yīng)用-案例。該項(xiàng)目自2011年以來一直在開發(fā)中，并將于2019年全面生產(chǎn)，并將由科學(xué)航空公司的科林堡、CO和WY的夏延地區(qū)進(jìn)行。
黑色Corintho 800是一種高溫工裝板，可供400°F使用，提供低CTE、高維穩(wěn)定性和高導(dǎo)熱性。它旨在生產(chǎn)原型，或低體積模具，是杜納集團(tuán)開發(fā)的高溫工裝系統(tǒng)的一部分，由黑色Corintho系列工裝板、Dunapox黑AD 135高溫環(huán)氧膠粘劑和Dunapox黑海125高溫環(huán)氧密封板組成。
Scion Aviation has completed prototype tooling for the external fuel pods for their upcoming SH-410 and SH-415 Vixen manned/optionally manned helicopter system, using a new state-of-the-art tooling board from Duna-USA, the Black Corintho 800.
High-temp polyurethane tooling board to maintain tight tolerances on carbon fiber components for autonomous helicopter
In preparation for upcoming flight tests, Scion needed to create external carbon fuel tanks for the Vixen helicopter line, and maintaining accuracy was key. The Black Corintho 800 was utilized in a direct-tool application, and once the boards were bonded, CNC machined, and sealed, Hexcel M35-4 epoxy prepreg was layed up onto the tool, and cured in an autoclave for 16 hours at 50 PSI/180°F.
“For years, making low-cost, highly accurate prototypes with the available tooling options was next to impossible. metal tooling is heavy, expensive, and overkill 9 times out of 10 for this type of application. The natural solution is tooling board, but traditionally, the co-efficient of thermal expansion has proven to be prohibitive to maintaining the necessary tolerance for a highly-accurate prototype,” says Jim Sampson, owner of Scion Aviation. “For Scion, the Black Corintho 800 fits the sweet spot in this regard in that it is highly stable, has an ultra-low coefficient of thermal expansion, and significantly sped up our process allowing relevant savings in time and money. It has truly changed our working method and enabled us to be more competitive in our quoting process.”

The Vixen helicopter line consists of unmanned/optionally manned variations, and is currently undergoing flight testing by Scion Aviation in collaboration with Safran for ultimate use as offshore patrol vessels (OPV) and other applications for the US Navy, US Army and civilian use-cases. The program has been in development since 2011, and full-scale production is slated for 2019 and will be conducted by Scion Aviation’s Fort Collins, CO and Cheyenne, WY locations.
The Black Corintho 800 is a high-temperature tooling board, designed for use up to 400°F, offering low CTE, high dimensional stability, and high thermal conductivity. It is designed to produce prototype, or low-volume tooling, and is part of a high-temperature tooling system developed by the DUNA Group consisting of the Black Corintho series tooling boards, Dunapox Black AD 135 high-temp epoxy adhesive and the Dunapox Black Sea 125 high-temp epoxy sealer.
