Polymer Composite Articles

摘要

The present disclosure pertains to resins/filler/matting composites that are formed via a resin infusion process. Certain embodiments are directed to methods and systems that may be used to produce a moulded composite article. For example, a unitary polymer composite article comprising: 50% to 90% by weight of particles; 10% to 50% by weight of resin; and at least one layer of matting integrally incorporated in the unitary polymer composite.

1. A unitary polymer composite article for use in highly corrosive and/or wear-resistant environments comprising:
50% to 90% by weight of silicon carbide particles; 10% to 50% by weight of resin; and at least one layer of carbon fibers matting integrally incorporated in the unitary polymer composite, wherein the article has a tensile strength of above 25 MPa, a density of between 2 to 3 g/cc, a hardness of between 70 to 95 Shore D, a flexural strength of at least 50 MPa and the article is wear resistant and acid resistant and has a life span of between 15,000 to 200,000 hours in use.
