Biosteel using genetic factor transformation technology, with a strength three times that of aramid. Additionally, there are new bulletproof materials such as carbon nanotubes.
During the Soviet era, aramid materials were mostly used in military and aerospace fields, with limited civilian applications. However, with the dissolution of the Soviet Union and the deepening of market economy, these materials gradually shifted towards civilian markets. Russian aramid fibers, unlike Kevlar and Twaron, belong to the heterocyclic aromatic polyamide type.
Russia's basic research is extensive and deep, and its aramid materials have advantages over similar products in Europe and the United States. However, the industrialization level is low, with small output. Currently, Russia is actively expanding its market and increasing production. The famous Kamensk Chemical Combine in Russia is cooperating with China to invest in fiber and fabric production. It is believed that in the near future, the Chinese market will see high-performance Russian aramid bulletproof products.
Polybenzoxazole (PBO) fibers have much higher tensile strength and modulus than aramid fibers, earning them the title of "king of fibers." In 1999, Japan introduced PBO fibers under the trademark Zylon, but as the duration of use extended, the drawbacks of this fiber became apparent. Tests have shown that the performance of this fiber gradually decreases below 100°C or under normal sunlight exposure. Particularly, after two incidents of Zylon bulletproof vests being penetrated, the application of PBO fibers in the bulletproof field has been further questioned. After more than 10 years of effort, Akzo Nobel has developed a new type of rigid polybenzoxazole polymer called M5, which surpasses aramid in performance. Magellan Systems International of the United States purchased this patent and jointly developed its application in bulletproofing with the U.S. Army.
With the development of biotechnology and genetic protein engineering, scientists from the United States and Canada have jointly developed a super high-strength fiber called Biosteel using genetic factor transformation technology, with a strength three times that of aramid. Additionally, there are new bulletproof materials such as carbon nanotubes.
