Group 1 - The core resource in the 21st century is talent, with its true value lying in technology, enabling countries to dominate markets when they possess unique technologies [1] - Aramid paper, a high-fiber polymer, has superior physical properties, being six times harder than steel while weighing only one-fifth of it, and is crucial in high-tech fields due to its high-temperature resistance [3][8] - The aerospace industry has significant costs, with rocket launch expenses ranging from $100 million to $300 million, and reducing rocket weight can save millions in launch costs [5][6] Group 2 - Aramid paper is widely used in aerospace, military, and civil aviation sectors, where weight reduction leads to cost savings, increasing demand for this material [8] - Historically, China lacked the technology to produce aramid paper, which was monopolized by the US and Japan, leading to inflated prices despite low production costs [10] - Chinese company Longbang Group has successfully overcome technological barriers to independently develop its own brand of aramid paper, attracting significant interest and investment in this emerging industry [12] - With increasing domestic production capacity and technological advancements, China is moving towards self-sufficiency in aramid paper, aiming to meet domestic demand and establish a presence in the international market [14]
