A disclosed screening apparatus includes a subgrid, and a screen element attached to the subgrid via laser welding at a plurality of attachment positions such that, under vibrational excitation, the screen element has a pre-determined profile of vibrational motion relative to the subgrid. The screen element may be attached at a maximal number of attachment locations to the subgrid to minimize relative motion of the screen element and the subgrid under vibrational excitation, or the screen element may be attached a sub-set of the maximal number of attachment locations to allow vibrational motion of the screen element relative to the subgrid. A disclosed method may include attaching a plurality of screen elements to a respective plurality of subgrids, attaching the plurality of subgrids to one another to form a screening pre-assembly, and cutting edges of the screening pre-assembly to form the screen assembly having a perimeter with a pre-determined shape.

A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

A fiber composite material component has fiber bundles and a matrix of thermoplastic and/or thermosetting material. The fiber bundles are arranged such that they form a profile. Bracing structures are arranged between the fiber bundles. At least two fiber bundles are arranged in a skewed manner with respect to one another and at least one cavity is formed in the region of the intersection of the skewed fiber bundles. Furthermore, a method for producing a fiber composite material component having fiber bundles and a matrix of thermoplastic and/or thermosetting material, is provided.

Systems and methods are provided for curing composite products. One exemplary embodiment is an edge breather for composite manufacturing. The edge breather is formed of a rigid material and includes an elongated body having a top open structure with a cross section that defines an arch. The edge breather also includes hollow passageways within the elongated body that are underneath the top structure and travel along a length of the elongated body. The top open structure defines multiple openings forming an open mesh through which air may enter.

An open-channel stiffener for stiffening a panel has a bonding flange for bonding the stiffener to the panel through a bondline formed between the bonding flange and the panel to form a stiffened panel. The open-channel stiffener has a cross-sectional shape that aligns, or substantially aligns, a shear center of the stiffener with a centroid of the stiffener and aligns the shear center proximate an edge of the bondline, and removes the need for a radius filler noodle. A plurality of perforations may be formed through the bonding flange to permit an adhesive to wick into the perforations and create a mechanical interlock between the bonding flange and the panel.

The invention relates to a plastics connecting seam for the fluid-tight connection of at least two plastics surfaces. The plastics connecting seam is in the form of a plastics connecting seam that supports strength under a load in such a way that a load acting in a standard load direction increases the connection strength of the seam.
