Quality of all-composite pressure vessels is internationally recognized

Infinite Composites Technologies has become the first company that produces liner-less all-composite pressure vessels to receive the high recognition of their Quality Management System – the certificate AS9100D.

Infinite Composites Technologies (ICT) is a producer of all-composite vessels of the 5 generation (without a liner) designed for the pressurized gas. Currently, the most popular reinforcement for this vessel type is carbon and glass. However, basalt fiber and aramid fibers like Kevlar have been increasingly used of late due to the contrasting mechanical properties such as impact resistance, and low temperature resistance.

The company comments that there is also a need in hybrid vessels which could either use distinct and separate layers of fiber for different roles such as impact/ abrasion resistance, or different fibers in the same band to get the properties of both fibers throughout the laminate.

Liner less all-composite vessels is a remarkable step forward in the technology development. The lack of an inner plastic liner considerably reduces the weight of a cylinder or a tank, so the fuel weight can exceed the cylinder weight itself. The lack of an inner reinforcing liner also provides users with more fuel storage compared to other composite tanks.

These qualities are in great demand in the aerospace, automotive and heavy vehicles as well as in the fields, where the weight and size of a cylinder or a fuel tank are critically important and leads to significant economic benefits, estimated from hundreds to thousands millions of dollars.

Received by Infinite Composites Technologies, the certificate AS9100D is issued by the International Aerospace Quality Group. It was collectively developed by major aerospace organizations such as Boeing, Lockheed Martin, and Raytheon, among others in order to satisfy DOD, NASA and FAA quality requirements.
