Abstract:
A solution to some of the problems related to manufacturing of fibre -reinforced composite panels is to provide a vacuum bag frame assembly, where said assembly comprises a tubular centre frame (2), a first vacuum bag frame (3) holding a first vacuum bag (30) arranged for closing against one side of the centre frame and a second vacuum bag frame (4) holding an second vacuum bag (40) arranged for closing against an opposite, second side of the centre frame. The centre frame is provided with a peripherally vacuum outlet external relative to the space between the vacuum bags, and one or more vacuum apertures directed internally relative to the space between the first and second vacuum bags and the centre frame. Said centre frame further comprises a tubular auxiliary frame (25) having a cross-section larger than the separation between the first and second sides of the centre frame, thus forming shoulders (26) for positioning and maintaining the relative position of said first and second vacuum bag frames.
Abstract:
A processing line for manufacturing of one or more vacuum bag frame assemblies where the processing line has a main frame and a pair of furnace half chambers, where the main frame is arranged for supporting the vacuum bag frame assemblies, and the furnace half chambers are arranged for enveloping one or more of the one or more composite lay-ups and further arranged for moving relative the vacuum bag frame assemblies.
Abstract:
The invention is an antiballistic armour plate comprising one or more layers of one or more antiballistic ceramic plates (2) laminated with a first, underlying fibre reinforced thermoplastic layer (8) comprising a first thermoplastic material (88) and reinforcement fibres (82), the antiballistic ceramic plates (2) arranged for receiving and deforming ballistic projectiles or shrapnel, and underlain by a spall liner (10) of one or more loosely bound sheets (11) of antiballistic fibres (12) arranged for receiving the ballistic projectiles or shrapnel having penetrated the ceramic plates (2). The antiballistic armour plate further has one or more of the antiballistic ceramic plates (2) provided with holes (3, 38) distributed across the one or more ceramic plates (2), wherein the holes (3, 38) have apertures at least toward the first, underlying thermoplastic layer (8) and provided with a thermoplastic matrix (4, 48) compatible with the first thermoplastic matrix material (88) and provided with reinforcement fibres (5, 58).
Abstract:
A sail headboard, clew board or tack, for forming a reinforced transition between a sail (10) and a halyard rope or wire (9), clew or tack rope, or similar, comprising the following features: a first and a second headweb (8) having matrix impregnated area portions (81) arranged adjacent each other, and each headweb (8) having a sewing portion (82) continuing outside at least one side of said impregnated portions (81), said sewing portion (82) being flexible and less impregnated or non-impregnated, said sewing portion for being arranged on either sides of a sail and fixed to said sail (10); said headweb (8) being reinforced at least by tension fibres (12) to be aligned with local tension lines or fibres (112) included in said sail (10).
Abstract:
Antiballistic panel comprising the following characterized in the following construction: At least a structural bottom plate made of for instance fiber reinforced thermoplastic (PP, PET or similar) with reinforcing fibers (glass fiber, carbon fiber, aramid fiber or similar); A first, underlying gluing foil or film that at the same time is functioning as a sealing film of thermoplastic or similar that substantially is not-mixable with the thermo plastic in the structural bottom plate; At least two or more antiballistic substantially matrix free fiber amour cloths with less than 20% weight between sufficient adhesive glue foils or thermoplastic foils I thermoplastic net; An overlying sealing film of thermoplastic or similar that substantially is not mixable with the thermoplastic of another structural top plate; Where the at least one another structural top plate made of for instance fiber reinforced thermoplastic (PP, PET or similar) of reinforcing fiber (glass fiber, carbon fiber, aramid fiber or similar). This arrangement is baked under vacuum bag in a form or upon a desired surface (for instance a chassis part) in an oven or is otherwise heated up under vacuum bag, until the thermoplastic melts and fills the reinforcing fiber of the bottom plate and the top plate and does not penetrate into the antiballistic cloths fibers, and at the same time as the antiballistic cloths intermediate foils with glue or thermoplastic foil / thermoplastic melts and in bonding the antiballistic cloths to the desired degree.
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 second hub (1) by a clamp (5) during connection.
