A Different Approach to Classic Structural Reinforcements Using Recycled Synthetic Materials

The aim of this paper was to test viable alternatives to classic materials used as reinforcements, like: steel, fiber reinforced polymers or carbon fiber reinforced polymers, in order to produce cheaper and more eco-friendly structural elements with similar or better behavior under service.PET straps and bonded polyester yarn straps are some of the most used materials in the packaging industry, with remarkable tensile strength almost similar to steel bands and are easily recycled, therefore came the idea that those materials could be used as reinforcements instead of steel or other materials providing an economical and more eco-friendly alternative.Experimental research was made to see if these straps provide the necessary pull-out resistance as they are imbedded in the structural element, in order to add the needed extra flexural strength.Four point bending test on glue laminated timber beams reinforced with these straps were also conducted to see actual improvements over standard non-reinforced beams.As supposed, significant improvement on the flexural behavior of the tested elements were observed proving that these straps are a viable alternative over standard reinforcements for lightweight and economical structural elements with a lower carbon footprint, with no increased fabrication costs.
