Throughout the annals of time, composites have emerged as an indispensable force, leaving an indelible mark on human civilization. From the rudimentary shelters that harboured our earliest societies to the groundbreaking advancements that fuel our aspirations for the future, composites have been vital throughout history, propelling progress and enriching our world from ancient dwellings to future innovations.
Unyielding in their transformative potential, these remarkable composite materials have stood as beacons of ingenuity and resilience, forever enhancing our collective existence. Regardless of the era, composites persistently pioneer innovation, transcending time to sculpt a brighter tomorrow.
Let’s explore the remarkable evolution of composites throughout history, from ancient times to the present, and catch a glimpse into the boundless possibilities that lie ahead in the future of these remarkable materials.
The concept of composite materials dates back to ancient times when civilizations creatively utilized the resources around them to construct dwellings. One notable example is the ancient Mesopotamians, who around 3400 B.C., developed plywood by glueing wood strips at various angles. Similarly, other civilizations employed mud/straw and wood/clay composites, forming the basis for building structures like bricks made from mud and straw.
In the late 1800s, canoe builders began experimenting with laminates made from different materials. They tried bonding layers of kraft paper using shellac but faced limitations due to inadequate materials. However, between 1870 and 1890, the development of synthetic resins opened new possibilities. These polymer resins could be converted from liquid to solid through a process called polymerization, and their molecules could be crosslinked to transform them from liquid to solid states.
The 1930s marked a significant turning point for resins and the composite industry as a whole. In 1936, unsaturated polyester resins became the preferred choice for composites manufacturing due to their curing properties. Epoxy resins and other high-performance resin systems also emerged during this period.
In the late 1930s, thin strands of glass fibres were manufactured followed by weaving them into a textile fabric. Combined with synthetic resins like polyester, these glass fibres composites created strong and lightweight composites.
During World War II, the composites industry experienced further growth as military applications demanded lighter yet stronger materials. Fibreglass composites became a prominent choice, with over seven million pounds of it used for military purposes by 1945. The corrosion resistance of fibreglass composites soon attracted attention, particularly in the oil industry, where fibreglass pipes were introduced in 1948.
Following the war, composites continued to gain popularity and expanded rapidly during the 1950s. Various products, including boats, trucks, sports cars, storage tanks, pipes, and ducts, were constructed using composites. Manufacturing methods like pultrusion, vacuum bag moulding, and filament winding were developed during this period.
Although carbon fibre was patented in 1961, it took some time for carbon fibre composites to become commercially available. However, when they did, they revolutionised various industries such as aerospace, automotive, marine, and consumer goods. The development of new and improved resins further fueled the demand for composites, particularly in high-temperature and corrosive applications.
In the late 1970s and early 1980s, composites made their way into infrastructure applications in Europe and Asia. The world witnessed the construction of the first highway bridge reinforced with composites and the installation of the first all-composites bridge deck. In the 1990s, the trend continued with the installation of the first all-composites pedestrian bridge in Aberfeldy, Scotland, the first FRP-reinforced concrete bridge deck in McKinleyville, West Virginia, and the first all-composites vehicular bridge deck in Russell, Kansas. FRP composites found use in state and national parks, where they were installed in remote locations inaccessible to heavy construction equipment, as well as for spanning over roadways and railways.
Today, composites are an integral part of numerous industries such as manufacturing, construction, and transportation. FRP composites systems are widely used worldwide to strengthen and seismically upgrade reinforced concrete and masonry structures, including buildings, parking garages, and transportation structures like bridge columns and decks. In the early 2000s, nanotechnology emerged as an essential component of commercial products. Composites incorporating carbon nanotubes provide enhanced mechanical, thermal, and electrical properties. Nano-materials are integrated into advanced fibres and resins used in the production of new composites.
The rise of 3D printing in the 2010s brought manufacturing capabilities into homes and small businesses. Composites companies have embraced this technology, utilising reinforced fibres in 3D printing processes across various sectors, including automotive, aerospace, tooling, medicine, and infrastructure. These reinforcements offer the strength of composites while reducing material usage and manufacturing time. Moreover, desktop 3D printing allows for the design and prototyping of composite-based products.
The composites industry continues to evolve, with ongoing efforts to make advanced composites more cost-effective and energy-efficient. The development of new fibres and resins will enable the creation of more applications for composites. Environmentally friendly resins incorporating recycled plastics and bio-based polymers align with the growing demand for stronger, lighter, and environmentally conscious products. Composites are poised to continue making significant contributions, shaping a better future across various sectors and industries.
