Core Viewpoint - Ceramic matrix composites (CMCs) exhibit excellent high-temperature performance and have broad applications in aerospace, nuclear power, and automotive industries, with significant market potential. China leads in brake and thermal protection for aircraft but lags in aerospace engine applications. The demand for CMCs in China's aerospace industry may reach a turning point in 2024, driven by advancements in production technology and cost reductions [2][12]. Group 1: CMC Characteristics and Applications - CMCs are defined as composites that incorporate reinforcing materials into a ceramic matrix, resulting in superior properties such as high-temperature resistance, low density, and high strength [3][19]. - SiCf/SiC composites are a research focus due to their excellent oxidation resistance and longevity, making them ideal for aerospace engine applications [4][26]. - CMCs are increasingly recognized as strategic materials for next-generation aerospace engines, capable of withstanding temperatures significantly higher than traditional nickel-based superalloys [29][33]. Group 2: Market Growth and Demand - The global CMC market was valued at $11.9 billion in 2022 and is projected to grow at a CAGR of 10.5%, reaching $21.6 billion by 2028, with the highest market share in defense and aerospace sectors [5]. - The demand for CMCs in the aerospace sector is expected to surge, particularly for components like combustion chambers and turbine blades, as countries strive for higher engine efficiency and reduced emissions [32][40]. Group 3: CMC Production and Industry Landscape - The production of CMCs involves complex processes with high barriers to entry, including fiber preparation, preform weaving, interface layer preparation, and matrix densification [6][7]. - General Electric (GE) has established a vertically integrated CMC supply chain, significantly increasing production capacity and demonstrating successful applications in various engine components [6][40][41]. - China's CMC industry has developed a relatively complete supply chain, with advancements in silicon carbide fiber production and CMC applications, particularly in brake materials for aircraft [8][10][11]. Group 4: Future Investment Opportunities - The anticipated turning point in demand for CMCs in China's aerospace industry presents substantial growth potential for related companies, especially as production technologies improve and costs decrease [12][8]. - As the application of SiCf/SiC composites matures, upstream raw material demand will increase, leading to potential rapid growth for midstream CMC component manufacturers [12][10].

Core Viewpoint - The company, Shaanxi Zhongtian Rocket Technology Co., Ltd., has approved a proposal to expand its business scope to include "solar power generation technology services" and has revised its articles of association accordingly [1][2]. Business Scope Changes - The company has added "solar power generation technology services" to its business scope, which previously included various technology and engineering services, manufacturing, and sales related to aerospace and intelligent systems [1][2]. - The revised business scope now includes services such as artificial intelligence application system integration, Internet of Things technology services, and engineering management services, among others [1][2]. Approval Process - The proposal for the change in business scope is subject to approval by the company's shareholders and the market supervision administration, with the final content dependent on the approval results [2][4].

Group 1 - The board of directors of Shaanxi Zhongtian Rocket Technology Co., Ltd. held its 22nd meeting on July 23, 2025, with all 9 directors present, complying with relevant laws and regulations [1][2] - The board approved the proposal to change the business scope and amend the company's articles of association, with a unanimous vote of 9 in favor [1][2] - The board also approved the proposal to convene the second extraordinary general meeting of shareholders in 2025, again with a unanimous vote of 9 in favor [2] Group 2 - The meeting was convened by the chairman Cheng Hao and included attendance from supervisors and senior management [1] - The resolutions from the meeting will be published in major financial newspapers and on the company's official website [1][2]
