Abstract
A fan impeller made of complex three dimensional composite structures which results in the combination of mechanical properties and abrasion and erosion resistance which allows for improved utility, functionality, reliability, cost, and safety for the user. The specific composite structures vary based on fan size and design as well as the gas and application requirements relative to such as but not limited to temperature, corrosivity, abrasiveness, etc., and may include but are not limited to combinations of fibers, resins, 3D printed reinforcement structures, cast reinforcement structures, and/or fabricated reinforcement structures.
Claims20
A centrifugal impeller, comprising:
- a body formed of a composite material, the composite material including fibers and a binder;
- and
- an anti-abrasion component forming part of the body, the anti-abrasion component including a mechanical coupler, the anti-abrasion component being held within the body via the mechanical coupler, the anti-abrasion component having a body portion and a coupling portion extending from the body portion, wherein:
- the coupling portion includes a first surface, a second surface opposite to the first surface, a first side, a second side opposite to the first side, a first end, and a second end opposite to the first end, the first end is proximate the body portion, and a thickness dimension of the second end is larger than a thickness dimension of the first end, and
- the mechanical coupler includes a textured portion that is formed by several projections, one of the first surface, the second surface, the first side, and the second side includes the textured portion, and the projections are spaced apart from each other and from the first side and the second side.
A composite impeller for a centrifugal impeller, the composite impeller comprising:
- a body including an end, the body being formed of a composite material including fibers and a binder;
- and
- an anti-abrasion component being coupled to the composite material and forming part of the body, the anti-abrasion component including a mechanical coupler, the anti-abrasion component being held within the body via the mechanical coupler, and the anti-abrasion component being located at the end of the body, the anti-abrasion component having a coupling portion including a first surface, an opposite second surface, a first side, an opposite second side, a first end, and an opposite second end, a thickness dimension of the second end is larger than a thickness dimension of the first end, and the coupling portion having a mechanical coupler that includes projections extending from one of the first surface, the second surface, the first side, and the second side, wherein the projections are spaced apart from each other and from the first side and the second side.
A centrifugal impeller, comprising:
- a body formed of a composite material including fibers and a binder;
- and
- an anti-abrasion component forming part of the body, the anti-abrasion component including a mechanical coupler that holds the anti-abrasion component within the body, the anti-abrasion component having a body portion and a coupling portion extending from the body portion, the coupling portion has a first surface, a second surface opposite to the first surface, a first end proximate to the body portion, and a second end opposite to the first end, a thickness dimension of the second end is larger than a thickness dimension of the first end, and the mechanical coupler includes a textured portion formed by several projections extending from one of the first surface or the second surface, wherein the projections are spaced apart from each other.
