Puncture-proof balloon and method of manufacturing such a balloon

摘要

The invention relates to a puncture-proof balloon and method of manufacturing such a balloon The invention relates to a balloon (1) comprising an assembly (5) comprising at least one outer textile layer (10) in the form of a balloon, which comprises at least one outer textile element ( 15) comprising at least one thread A and / or fibers A, and at least one thread B and / or fibers B, the thread A and / or the fibers A comprising at least one material A having a melting temperature or decomposition TA, and the yarn B and / or the fibers B comprising at least one polymeric material B having a melting temperature TB, TA being greater than TB. The assembly (5) comprises a balloon-shaped polymeric matrix (30) of the outer textile layer (10), and the outer textile layer (10) comprises at least one fused area in which said at least one polymeric material B is molten and at least partially forming the polymer matrix (30). The assembly (5) defines an internal volume (4) whose pressure is substantially equal to atmospheric pressure. Figure for the abstract: Fig. 2.
