Taiwan Facilities & Atomflo 500 Atmospheric Pressure Plasma

Visit to Taiwan facilities

Employees from surfx headquarters in Redondo Beach CA spent this week (April 9 to 15) working with employees at Surfx Technologies Tawian Co. Ltd., in Taichung.  At this facility we make our Atomflo 500 and SPM.  The staff of 7 at Surfx Taiwan covers all aspects of manufacture, including supply chain management, mechanical, electrical and controls engineering, software, assembly and administration.  This week, we worked together to implement several improvements to the Atomflo 500.  We have expanded the range of operation of the coolant control module (CCM), so that it will maintain the plasma source at any temperature from 35 to 120 oC.  At the low temperature, the plasma gas does not exceed 72 oC.  This operating temperature is well suited for treating polypropylene and polyethene tubing.  Activation rates are fast, and there is absolutely no potential for thermal damage of these materials.  At the high temperature end, the plasma gas will exit the source at about 150 oC.  This hotter condition will boost surface etching rates, and improve your process speed.

Surface preparation in the aerospace industry

One of the most common applications that we see here at Surfx is the need for surface preparation in the aerospace industry. Materials such as carbon fiber reinforced epoxy composites present a challenge when being incorporated into larger structures. The low surface energy of the base material does not allow for intimate contact with the adhesive being used, and the chemical functionalities present on the surface are not design for covalent linking to the adhesive material. As a result, the aerospace industry typically utilizes wet chemical and abrasive techniques to generate surfaces which are prepared for adhesive bonding. However these methods do not lend themselves to automation, and they also generate environmental waste.

I would like to bring your attention to some work we have done using our Atomflo plasma system to activate the surface of epoxy composite materials to yield robust, environmentally stable bonds. Our Atomflo plasma system works to generate a highly active epoxy surface by handling the 3 of the major barriers to good adhesive bonding. Initially, the plasma can strip away organic materials at the composite surface and allow for clean interaction between the composite and the adhesive being used. Once these materials are gone, the high density of oxygen atoms generated in the plasma will react with the composite surface to leave behind a high surface energy which facilitates intimate contact with the adhesive. Finally, specific chemical functionalities are generated that react directly with the adhesive being used. These plasma treatments are a permanent and covalent substrate modification. Surfx has been working for many years to understand and optimize this process. Please see the attached literature for a more complete description of this process, or contact us for a free demonstration of our Atomflo plasma system.

Atmospheric Pressure Plasma Activation of Polymers and Composites for Adhesive Bonding: A Critical Review

Atmospheric Pressure Plasma Activation of Polymers and Composites for Adhesive Bonding: A Critical Review

Read the Full Article Here

The strength of bonded joints is of great concern to the aerospace, automotive, medical device, and electronics industries [1]. Atmospheric pressure plasma acti-vation is rapidly gaining acceptance as a desirable method of surface preparation prior to bonding [1]. This technique provides an alternative to traditional methods of surface preparation by wet chemical cleaning and mechanical abrasion [1, 2]. Although these latter procedures are “tried and true,” they are time consuming manual processes. Moreover, in certain instances, they yield lower bond strengths, and can even result in damage to composites that are fabricated with high modulus fibers [1, 2]. Abrasion methods generate dust which is an environment, health, and safety concern. Consequently, there is a need to explore alternative, environ-mentally friendly approaches that activate the surface without damaging the bulk material. Atmospheric pressure plasmas show promise for fulfi lling this need.

This review article focuses primarily on atmospheric pressure plasmas that are self contained, and are suitable for the treatment of three-dimensional extruded parts, such as are common in many manufactured products. Plasmas used for this purpose are decoupled electrically from the workpiece. They produce an after-glow that contains neutral reactive species, which fl ow out and down onto the surface being activated. This may be contrasted to coronas and dielectric barrier discharges that are used to treat plastic fi lm. In this latter case, the polymer fi lm is passed between the powered and grounded electrodes in roll-to-roll fashion, and the fi lm is activated by contact with both ionized and neutral species. For more detailed information on the performance of these latter devices, the reader is referred to several excellent review articles [3–6].

In this paper, we examine published work using downstream, atmospheric pressure plasma to activate polymer and composite surfaces. First an overview of the physics and chemistry of atmospheric pressure plasmas will be given, along with a comparison of the different types of devices. Then, the efficacy of this technique for surface activation will be discussed in terms of the mechanical proper-ties, the water contact angle (i.e., surface energy), the surface roughness, and the surface composition. Lastly, we will consider the mechanism of polymer surface activation.

Surfx In The News: Plasma used for consistent surface preparation while increasing chemical bond.

Certification of bonded composite primary structures.

OEMs develop technology to quantify uncertainty in pursuit of the no-bolt bondline.

Composites have flown on commercial aircraft primary structures — those critical to flight — for more than 30 years, but only recently have they conquered the fuselage, wingbox and wings, most notably on the Boeing Co.’s (Chicago, Ill.) 787 Dreamliner and the A350 XWB from Airbus (Toulouse, France). These carbon fiber-reinforced plastic (CFRP) structures, however, still require assembly with thousands of mechanical fasteners. Why? Because it is the easiest and least expensive way to meet current certification requirements, which mandate proof that each and every adhesively bonded joint will not separate and cause structural failure should it reach its critical design load. But many in the industry argue that the full cost and weight savings of composites cannot be realized until bonded joints can be certified without fasteners.

The development of technologies to address this need has steadily progressed, from programs in the late 1990s such as the U.S. Department of Defense (DoD) Composites Affordability Initiative (CAI) to more recent initiatives, including the European Union (EU)-funded Boltless assembling Of Primary Aerospace Composite Structures (BOPACS) project. Here, HPC looks at current efforts to build a certification regime for bonded primary structures on aircraft. Boeing, Airbus and Lockheed Martin Aeronautics (Palmdale, Calif.) have mounted independent efforts toward that end. Their research offers the hope of building reliability into the bonding process, and of gauging final bond strength via a coordinated certification system that includes design, process control and quality assurance (QA).
