The Boeing 787 Dreamliner and the Airbus A350 airplanes are two early examples. What sets these planes apart from older planes is that their body and wings are made of composite materials rather than aluminum. They are more fuel efficient and fly farther. This reduces the cost of travel and opens up new routes. Passengers also enjoy benefits like increased humidity and cabin pressure. Humidity is increased from 4% to 15% and cabin pressure is increased from the equivalent of 8,000 feet above sea level to 6,000 feet above sea level. The bottom line is that these planes cost less to operate and provide passengers with ground level comfort and less jet leg.
Lightweight advanced materials are all around us. These materials have low densities and include carbon fibers, glass fibers, metals, alloys and intermetallics, polymers, ceramics, nanocarbon and other nanomaterials, aerogels, bio-based fibers, composites of polymers, metals and ceramics, and structural materials. The materials can be fabricated in various structural forms, such as, open-cell and closed-cell foams, honeycombs and porous scaffolds for lightweighting benefits. Nature, as usual, is always ahead and deploys lightweight cork, balsa, sponge and bone. Pangaea Ventures monitors the technology innovation stream closely and have portfolio companies whose products benefit lightweighting applications. Some of our Strategic Limited Partners actively participate in the lightweight materials markets with leading edge products.
