Adhesive-Bonding Training

Safety aspects should partner the measures practised within a quality system, and they represent a vital part of the education and training of the personnel involved. The history of adhesive bonding has shown that accident and health problems associated with the technology are rare. Nevertheless, any material which is used without suitable precautions can become an unreasonable risk to health, safety, property, and the environment. The actual hazard presented by the use of materials depends not only on its potential hazard, but also on the conditions under which it is used. Concentration and duration of exposure to hazardous materials is generally the critical element in determining risk factors. [Pg.194]

P(l) Only properly trained and skilled personnel may perform adhesive bonding. [Pg.193]

It is important to realise that structural bonding is critical and demanding work, comparing well with welding as a task requiring special skills and knowledge. Because of this, only properly trained personnel should be allowed to perform adhesive bonding. [Pg.484]

Nevertheless, auto makers and adhesive formulators have been able to work around these difficulties and structural plastics are being used in increasing amounts. For example, the hood of the 1984 Pontiac Fiero consists of two plastic panels adhesively bonded together. The RRIM panels on the car s doors are also adhesively bonded. Ford has recently built an experimental car in which the body, chassis, and power train are made of graphite-reinforced composites. Almost the entire assembly, including primary load bearing joints, was bonded with a polyurethane structural adhesive in place of mechanical fasteners or welds. ... [Pg.202]

Figure 4 Modem trains owe their stylish looks to a combination of glass, plastics and lightweight metals bonded together with adhesives, (a) Train before cabin bonding.

Successful completion of a course allows the participants to effectively apply adhesive bonding technology in their work area. All persons who are involved in adhesive bonding technology are highly recommended to take relevant training courses. [Pg.978]

Non-destructive testing can be as simple as a visual inspection as a trained eye will detect a surprising number of faulty joints, including close inspection of the adhesive bond line at the joint periphery, misaligned parts or uneven adhesive bond lines. [Pg.142]

SHORT COURSES AND WORKSHOPS ABARIS TRAINING 5401 Longley Lane, Suite 49, Reno NV 89511, (775) 827-6568. Several courses related to adhesives and composites bonding and repair for aircraft. [Pg.46]

Proper intervention planning and design, workmanship and quality control are essential since the non-reversibility of adhesion does not allow inspection and correction after cure. Compared to currently used mechanical timber joints, bonding requires more skilled and well-trained operators, and better organisation and record keeping for future traceability of possible problems and defective joints. [Pg.284]

Nondestructive testing (NDT) is far more economical, and every assembly can be tested if desired. However, there is no single nondestructive test or technique that will provide the user with a quantitative estimate of bond strength. There are several ultrasonic test methods that provide qualitative values. However, a trained eye can detect a surprising number of faulty joints by close inspection of the adhesive around the bonded area. Table 7.16 lists the characteristics of faulty joints that can be detected visually. The most difficult defects to be found by any method are those related to improper curing and surface treatments. Therefore, great care and control must be given to surface-preparation procedures and shop cleanliness. [Pg.453]

Special training may be required selection of the optimal adhesive and bonding process may be difficult and relates only to the intended application. [Pg.342]

Adhesive producers soon realised that this technology could also be used for similar applications in buses, trucks or trains. The demand for this innovative Elastic Bonding fastening technique initiated the development of the Sikaflex -Technology based on polyurethanes. [Pg.358]

Another fundamental mechanics solution that has many applications in bonded joints is that of a beam on an elastic foundation. Emil Winkler first reported this analysis in 1867 [49]. The method has been widely applied to a variety of problems, perhaps most obviously that of trains passing over rails supported by the earth, and has been included in most texts on advanced mechanics of materials [16]. Since many bonded Joints have beam-like adherends supported by a more flexible adhesive layer, this model of a beam on an elastic foundation is also of great importance for a variety of joints ranging from the lap shear specimen to fracture specimens, from peel specimens to the loop tack test.

The ceiling of decks and inspection lid for Shinkansen and limited express cars are made of aluminum corrugated panels ( Fig. 47.6) bonded with an epoxy adhesive (Sugano 1992). Limited express is a special train faster than ordinary expresses in Japan. [Pg.1216]
