Why Are Researchers Fascinated by Wood for Satellite Manufacturing?
Previously used in cars and planes, wood has now ventured into space, with the launch of the first wooden satellite in early November. What will be the next innovative use for wood?
Wood: A Resource for the Future?
Wood, a familiar natural material utilized for millennia, is making a strong comeback in unexpected fields. In early November 2024, a groundbreaking all-wood satellite was launched into space. This innovative project, led by researchers from Kyoto University in Japan, is reshaping how we view wood in construction.
Wood: A Time-Tested Raw Material
Wood has been integral to human development, used in wheel-making around 4000 BC and facilitating movement. It played a role in vehicle construction, notably in the Mosquito, one of the finest aircraft of World War II. Today, Robin Aircraft in Dijon has produced over 2700 units of the wooden DR 400 airplane.
Wood: An Abundant and Sustainable Resource
Wood is not only lightweight and sturdy but also plentiful. Europe’s forest cover increased by 30% between 2000 and 2020, and France’s doubled over the past century. For optimal use in construction, hardwoods like poplar or birch are preferred for their structural suitability.
Wood: A Complex Material
Despite its benefits, wood is complex to work with, varying significantly depending on its part of the tree and environmental conditions. Scientists have developed methods to understand and manage these complexities.
Concrete Applications in the Automotive Industry
Wood is also being extensively researched for automotive use, where vehicles need to withstand impacts. Wood tubes reinforced with glass or carbon fibers have proven effective in crash tests.
Wood in Space
The most astonishing use of wood may be its application in space. The first wooden satellite, launched in early November 2024, is environmentally friendly, fully incinerating upon re-entry and naturally radio wave transparent, enhancing communication.
In conclusion, wood, a historic material, continues to offer significant potential and may well be a construction material of the future.
