State Intellectual Property Office of Croatia receives patent application for solar cells integrated into fiberglass boat hull from ICAT DOO

The State Intellectual Property Office of Croatia has received a patent application for solar cells integrated into a fiberglass boat hull from ICAT DOO. The invention was developed by Uroda Tomislav, Culic Niksa and Jadresic Klement.

The abstract issued by State Intellectual Property Office of Croatia explains: Integration of solar cells into the GRP surface is achieved within the GRP process of shipbuilding in such a way that on the external surfaces of vessels solar cells are integrated in one of the layers of the GRP laminate. The term glass reinforced plastic or GRP implies the technology that uses fiber texture as reinforcement material and resin as a bonding material, resulting in the GRP product. Technical process of integrating solar cells has to be performed in accordance with the technical procedures, implying usage of certain materials and the following appropriate procedures for GRP technology. Solar cells are placed in one of the first layers of GRP laminate.

The primary purpose of this invention is to place solar cells in one of the layers when building new vessels, but this invention applies also to the already built vessels, by coating them in GRP with solar cells in one of the layers.



United Technologies Corporation files WIPO patent application for engineered high fiber volume polymer matrix composites

United Technologies Corp has filed a patent application for engineered high fiber volume polymer matrix composites. This invention was developed by Jalowka Joseph.
