On one hand, there are rivets, bolts, and welds. These are methods that clearly show how they work, mechanical technologies we understand very well and have been using for a long time. There's no need for someone to explain how to fasten a bolt or how this mechanism manages to hold two metal pieces together tightly. Moreover, we are used to seeing ships, buildings, and even bridges held together by large bolts, and we take for granted that two metals can be joined through welding. For all these reasons, we naturally tend towards these mechanical fastening solutions, which are familiar and "simple." Yet, despite this, we know that in many industrial sectors, for various needs, the same rivets, bolts, and welds have often been replaced by the use of structural adhesives. These glues have become the default solution for bonding metals, plastics, and many other materials due to their numerous advantages, such as increased lightness, instant bonding, no need for pre-drilling, clean aesthetics, and more. These points could also apply to high-performance tapes, not just structural adhesives. Still, the question often remains: do structural adhesives really work? Are they strong enough to replace rivets, bolts, and welds in your company? Let’s find out. We've already touched on what structural adhesives are, so we'll keep it brief here. In short, you could say they're extremely strong glues. If we want to give a qualitative definition, we could describe a structural adhesive as a glue that creates a bond at least as strong as the materials it is meant to join. But when it comes to strength, performance, and safety, qualitative descriptions can be insufficient. That's why in the United States, adhesives are considered structural if they have a shear strength of over 7 megapascals, while in Europe, the standard is even higher—there, an adhesive is only considered structural if it has a shear strength of over 10 megapascals. The typical structural adhesive is liquid and thermosetting, but there are several variations. It should also be noted that these products are not new. In fact, they are well-established. For example, 3M introduced the first neoprene-based contact adhesive in 1942, and in the 1960s, it launched the first flexible epoxide structural adhesive, as well as the first liquid spray adhesive. So, structural adhesives are a proven and well-regulated technology. Let's now see just how effective they truly are. To understand how and to what extent structural adhesives work, nothing is more useful than comparing them with the classic fastening solutions that they are sometimes called upon to replace. The most important data used to express the strength of a fastening solution is the previously mentioned shear strength. Which solution—flow welding, spot welding, rivets, bolts, or structural adhesives—provides the highest strength? Well, at the bottom of the list, with the worst results, are the famous rivets. They are cheap, quick to use, but they certainly don't stand out for design freedom or aesthetic appeal. Then come bolts, which, like rivets, can certainly provide high strength at the point where they are installed, but they cannot work across the rest of the surface. Slightly better is spot welding, but it still only works on specific points. The two methods that offer the highest shear strength are flow welding and structural adhesives, often performing up to three times better than the weaker rivets. With numbers in hand, structural adhesives work, often as well as or better than traditional fastening methods. They can be used in a wide range of applications: to bond metals, plastics, and composites, on both stable and flexible surfaces, to withstand extremely high or low temperatures, and much more.
