Adhesives that cure in a short time tend to be unstable during storage, while adhesives that are stable during storage tend to cure slowly. As a result, either heat or ultraviolet radiation is often used to hasten curing.
Dispensing two-part adhesives to assemble electric vehicles can be a challenge, particularly if the mix ratio is wide or the two components have different viscosities.
Several years ago, researchers from QSS Group Inc. and the Ohio Aerospace Institute were interested in finding a commercially available adhesive that bonds titanium pipes to carbon-carbon composite (CCC) sheets. The reason: Doing so would lower the cost of assembling spacecraft heat-rejection systems made of these joined materials.
Picking the right adhesive almost always entails a balancing act as engineers attempt to find products that meet conflicting end-use and manufacturability requirements. Medical device engineers, who also have to contend with a strict regulatory environment, often have the toughest time striking that balance.
Protecting one's hearing is always a smart thing to do. Hearing-aid manufacturer GN ReSound (GNR) believes that improving one's hearing is just as smart.
