The main trends in the composites world are:

1. Lightweight properties and cost savings – an increasing number of manufacturers are using carbon composites to create lighter, more energy-efficient products.
2. It should be noted that CNRP (nano-reinforced polymers) are used in the aerospace industry because they are stronger and offer approximately 30% less weight.
3. Carbon fibers will enable the construction of longer wind turbine blades, increasing the capacity of energy production.
4. As green policies have become more important, there is a strong rising demand for nano- and bio-resins.
5. Using composites to build railroad cars would result in a 30% weight reduction and a 5% reduction in energy consumption.
6. Composites are being used as insulators, electric box enclosures, and locomotive nose covers. Additionally, composite railroad ties are resistant to temperature, insects, and water, so the initially more expensive material pays off because the final product is considerably more resilient to environmental wear and tear.
7. Sheet molding compounds and modified epoxy glass are two further composites that will help the railroad sector meet its demand for lightweight components. Composites like balsa, foam, aluminum honeycombs, and cork composites are suitable for making lighter cores. They all offer a core that is both light and stiff. Sustainability is a feature of both natural fibers and bio-resins. They may produce lightweight structural components for both the inside and outside.
