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.

Underlying
Technology

Material Science and Engineering: Advanced composites and nanomaterials rely on advanced material science and engineering principles to design and optimize materials with specific properties.
Nanotechnology: Nanomaterials leverage nanotechnology, the manipulation of matter at the atomic and molecular level, to create materials with enhanced strength, durability, and other desired characteristics.
Manufacturing Processes: Specialized manufacturing processes, such as pultrusion, filament winding, and 3D printing, are used to create advanced composite components with precise geometries and tailored properties.

TRL : Varied, ranging from 4-5 (lab-scale development and testing) to 7-8 (commercially available and used in demonstration projects).

Prominent Innovation themes

Carbon Fiber Reinforced Polymers (CFRP): CFRP composites offer exceptional strength-to-weight ratios, making them ideal for lightweight structures and reinforcing existing concrete elements.
Glass Fiber Reinforced Polymers (GFRP): GFRP composites are cost-effective and versatile, used in a wide range of construction applications, including cladding, roofing, and structural elements.
Natural Fiber Composites: Utilizing natural fibers, such as flax, hemp, or bamboo, in composite materials offers sustainability benefits, as these fibers are renewable and biodegradable.
Nanomodified Concrete: Adding nanoparticles, such as silica nanoparticles or carbon nanotubes, to concrete can enhance its strength, durability, and resistance to cracking.
Self-Healing Composites: Incorporating self-healing agents or mechanisms into composite materials can enable them to repair cracks autonomously, extending their lifespan and reducing maintenance costs.
