Development of new methods of connecting materials without using harmful adhesives

Scientists at the Graz University of Technology (TU Graz) in Austria have taken a big step towards reducing the environmental impact of manufacturing industries by inventing two innovative methods in the field of material bonding. These methods, which work without the need for traditional adhesives, create strong and stable connections and have the potential to revolutionize different industries.

According to the scientific news department of Tekna Technology Media, industrial adhesives, which are widely used in various industries, bring significant environmental problems. These adhesives are usually petroleum-based and harmful chemicals are released in their production process. Also, after the end of the product’s life, these adhesives lead to soil and water pollution due to their non-degradability. To tackle these challenges, TU Graz researchers have introduced two innovative methods that are proposed as environmentally friendly alternatives to traditional adhesives.

In this method, using 3D printing technology, different materials penetrate directly into the pores of raw wood and create a strong and stable connection. This method has significant advantages in terms of both environment and health without the need for external adhesives. By using ultrasound waves, a strong connection is created between different materials. This method is especially suitable for connecting large parts and two-dimensional structures. The development of these new connection methods is an important step towards reducing the environmental impact of manufacturing industries and improving the quality of products. By replacing traditional adhesives with these environmentally friendly methods, a more sustainable future can be achieved.
