Advanced Composites and Nanomaterials for Construction Buildings

Detailed overview of innovation with sample startups and prominent university research

What it is

Advanced composites are materials made by combining two or more distinct materials, such as fibers and resins, to create a new material with enhanced properties. In construction, advanced composites typically involve high-strength fibers like carbon fiber, glass fiber, or natural fibers embedded in a matrix material, such as polymers or cement. Nanomaterials are materials with at least one dimension in the nanometer scale (1-100 nanometers), offering unique properties due to their small size and high surface area.

Impact on climate action

Advanced Composites and Nanomaterials in low-carbon construction materials significantly reduce carbon emissions by offering lighter, stronger alternatives to traditional materials like concrete and steel. Their use minimizes energy consumption in production and transportation, fostering sustainable building practices, thus contributing to a substantial reduction in the construction industry’s carbon footprint.
