  • Publication number: 20120192705
    Abstract: The invention is an antiballistic armour plate comprising one or more layers of one or more antiballistic ceramic plates laminated with a first, underlying fibre reinforced thermoplastic layer comprising a first thermoplastic material and reinforcement fibres, the antiballistic ceramic plates arranged for receiving and deforming ballistic projectiles or shrapnel, and underlain by a spall liner of one or more loosely bound sheets of antiballistic fibres arranged for receiving the ballistic projectiles or shrapnel having penetrated the ceramic plates. The antiballistic armour plate further has one or more of the antiballistic ceramic plates provided with holes distributed across the one or more ceramic plates, wherein the holes have apertures at least toward the first, underlying thermoplastic layer and provided with a thermoplastic matrix compatible with the first thermoplastic matrix material and provided with reinforcement fibres.

  • Patent number: 8215360
    Abstract: A solution to some of the problems related to manufacturing of fiber-reinforced composite panels is to provide a vacuum bag frame assembly for use in the production of fiber-reinforced composite panels, where the vacuum bag frame assembly comprises a tubular center frame, a first vacuum bag frame holding an integrated first vacuum bag and arranged for closing against a first side of the center frame, and a second vacuum bag frame holding a second integrated vacuum bag and arranged for closing against an opposite, second side of the tubular center frame. The tubular center frame is provided with a peripherally arranged vacuum outlet external relative to the space formed between the vacuum bags, and one or more vacuum apertures directed internally relative to the space formed between the first and second vacuum bags and the tubular center frame.

  • Publication number: 20120119487
    Abstract: A connector for pipes which are used for transportation of powder, grain, gas and fluids is designed such that pipes with a moderate angular misalignment can be connected without bending of the pipes, and without loss of sealing capacity, and comprises a first hub (2) and a second hub (1), wherein the first hub (2) has an external thrust ring (6) with spherical inner and outer surfaces which is pressed and locked against the first hub (2) by a clamp 5 during connection.
