blog about Startup Develops Lightweight Linerless Pressure Vessel Technology

Imagine a world where aerospace rockets can carry more fuel and travel farther, where aircraft significantly reduce fuel consumption while improving operational efficiency, and where ground storage and transportation systems can safely and efficiently handle high-pressure gases. Infinite Composites (IC), an AS9100D-certified company, is turning these possibilities into reality through its cutting-edge composite pressure vessels and structures.

IC stands out in the industry through several key advantages:

• Exceptional Certification: The AS9100D certification demonstrates IC's reliable quality management system and technical capabilities in designing and manufacturing advanced composite pressure vessels, meeting stringent aerospace standards.
• Unmatched Pressure Efficiency: IC's products offer superior pressure-to-weight ratios, providing significant weight savings without compromising performance.
• Accelerated Development Cycles: Leveraging scalable platform technology, IC reduces product development timelines and lowers non-recurring engineering costs for clients.

IC's innovative Infinite Composite Pressure Vessel (iCPV) eliminates the need for traditional metal or plastic liners, offering distinct benefits:

• Maximized Storage Capacity: The linerless design reclaims space typically occupied by liners, allowing for greater fuel or gas storage within the same external dimensions.
• Reduced Weight: By removing liners, iCPVs achieve significant weight reductions - crucial for weight-sensitive aerospace applications.
• Enhanced Reliability: The design eliminates potential liner failure points, improving overall safety and performance.

IC's engineering team specializes in developing tailored solutions for specific requirements, whether for target volumes, dimensional constraints, pressure needs, or other specifications. The company utilizes advanced CAD software and simulation tools to ensure design precision:

• Design Software: Fusion360, Inventor, Composicad, SimWind, Composite Designer
• Simulation Tools: AutoDesk Simulation Mechanical, MathCad, ESA Comp, Nastran

IC has successfully completed numerous projects across various sectors, including:
