Cross-Laminated Timber: Its Importance in Temporary Military Structures
Its uses in temporary military structures is gaining increased interest as a viable material. This property will enable rapid construction of deployable military shelters. But is CLT a good choice for such structures? Here are some reasons why. Let’s look at two examples:
It’s an Important Material
Cross-laminated timber (CLT) is a composite timber material that is relatively new and has gained much attention in North America and other parts of the world. This material is a great alternative to steel and concrete, and it possesses both unique mechanical and environmental properties. Compared to steel or concrete, CLT can be quickly constructed and can meet force protection standards. However, further testing is needed to determine the material’s blast and ballistic performance.
In order to determine its strength and durability, CLT is subjected to rigorous tests by the Forest Products Laboratory (FPL) of the U.S. Department of Agriculture. The lab tests wood against extreme conditions, including fire, earthquakes, and explosions. CLT is stronger than steel, and the material can withstand more than twice the weight of steel. Those tests, however, are primarily for military applications.
It has an inherent penetration resistance greater than that of dimension lumber and plywood
Dimensional wood is pressure-treated for varying applications. Pressure-treated lumber is stamped with its grade before treatment. The preservatives do not change the load-bearing ability of the lumber but provide protection against moisture. Kiln-dried treated lumber will shrink after treatment and may be sold as premium lumber. Some mills use this term to capitalize on the trend toward better-looking lumber among DIYers. Structural premium lumber, however, is bright wood.
Despite its superior performance in ballistics, temporary military structures have not undergone a radical transformation since World War II. Despite their lightweight nature, they require large numbers of workers to construct and deploy and offer minimal ballistic protection. To address these shortcomings, a new prefabricated engineered wood product called cross-laminated timber (CLT) has been developed. This new material has the potential to offer ballistic protection.
It Can Be Used for Quick Construction
The use of carbon fiber grid precast concrete technology has been proven successful in the field of military construction. The technology can be used for quick military construction. A simulated Iraqi village was constructed in a day by a group of U.S. Army engineers. The portable factories can also be transported and set up quickly. There are some challenges, but if these obstacles are overcome, the portable factories can be a good option for military construction.
It Can Be Used for Deployable Military Shelters
As a result, the market for deployable portable fabric structures is expected to grow at a CAGR of 5.3% during the forecast period. The demand for military shelter systems has increased in China, where the People’s Liberation Army (PLA) is undergoing massive reforms to make it the world’s leading maritime power. The country is focusing on controlling the South China Sea, as well as the Asia-Pacific region, which will further boost demand for military shelters.
