What is a composite?

Composites, with their adaptability and versatility, are materials that combine two or more different substances to enhance their properties. They usually include a reinforcing material, like fibers or particles, placed in a matrix material such as plastic, metal, or ceramic. This mix makes composites stronger, stiffer, and more valuable than the individual materials alone, creating many opportunities for innovation and design.

A short history of composites.

Composites, with their rich and significant history that spans thousands of years, connect us to our past and inspire us for the future. They started with simple materials, like mud bricks with straw, and have evolved into advanced products like carbon fiber and epoxy laminates. This history is a testament to the enduring power of human innovation and the potential of these materials to help us create new things.

Since ancient times, people have mixed materials to make more potent products. Civilizations like the Babylonians, Egyptians, and Chinese used basic composites for building and making weapons. Over time, new materials and better manufacturing methods led to more innovations.

Today, composites are crucial in many industries, including aerospace, automotive, sports equipment, and renewable energy. They are lightweight, strong, resistant to corrosion, and flexible in design, changing how we manufacture and engineer products and offering reliable solutions for various needs.
