Abstract
This invention is directed to an inflatable fibre reinforced bag having a flat and generally round shape in uninflated condition, comprising at least one interior elastomer layer, a fibre reinforcement structure and an outer elastomer layer, wherein a reinforcement structure consisting of continuously wound reinforcement fibers running from pole to pole substantially closes said poles.
Claims13
An inflatable, fiber reinforced bag having a flat and generally round shape in an uninflated condition, the inflatable, fiber reinforced bag comprising:
- at least one interior elastomer layer;
- a fiber reinforcement structure covering the at least one interior elastomer layer, the fiber reinforcement structure being formed by a continuous winding of fibers between opposite poles of the bag substantially closing each pole of the opposite poles, wherein the fiber reinforcement structure comprises a plurality of fiber reinforcement layers forming a packet of layers, and wherein a first fiber reinforcement layer, of the plurality of fiber reinforcement layers, located closer to an interior side of the bag is wound closer to a pole, of the opposite poles, than a second fiber reinforcement layer, of the plurality of fiber reinforcement layers, located more remote from the interior side of the bag;
- an exterior elastomer layer covering the fiber reinforcement structure;
- and
- an inflation valve unit penetrating the at least one interior elastomer layer, the fiber reinforcement structure and the exterior elastomer layer.
An inflatable, fiber reinforced bag having a flat and generally round shape in an uninflated condition, the inflatable, fiber reinforced bag comprising:
- at least one interior elastomer layer;
- a fiber reinforcement structure covering the at least one interior elastomer layer, the fiber reinforcement structure being formed by a continuous winding of fibers between opposite poles of the bag substantially closing each pole of the opposite poles, wherein the fiber reinforcement structure comprises a plurality of fiber reinforcement layers forming a packet of layers and an intermediate elastomer layer sandwiched between subsequent fiber reinforcement layers, of the plurality of fiber reinforcement layers:
- an exterior elastomer layer covering the fiber reinforcement structure;
- and
- an inflation valve unit penetrating the at least one interior elastomer layer, the fiber reinforcement structure and the exterior elastomer layer.
