摘要:
Composite materials that are configurable, their preparation, and their uses are described. A composite article includes a plurality of sheets positioned to interleave and partially overlap with each other and held together by interactions between the plurality of sheets and a compressive force across the plurality of sheets, wherein each of the plurality of sheets is infused with an elastomer and forms at least one smooth surface, wherein each of the plurality of sheets is in close contact with adjacent ones of the plurality of sheets, wherein an overlapping area of the plurality of sheets provides resistance to a shear force applied to the composite article.

A positive transport of carbon fiber bundles (150; 240, 245, 250, 255, 260, 265), in ribbon form, with in-line manipulation of the fiber bundles (150; 240, 245, 250, 255, 260, 265) (spreading or spreading and volumization with manipulators (110)) during fiber bundle transport to points of fiber bundle deliveries into a circular loom bed plate turntable (200) is described herein. The automated placements of these deliveries of the fiber bundle/tow (150; 240, 245, 250, 255, 260, 265) at selected orientations in the area correspond to the feeding zone of an improved circular loom bed plate turntable (200).
摘要:
A method and apparatus for forming a composite part. An apparatus comprises a tooling plate, a tab co-bonded with the tooling plate, and a group of alignment features associated with the tab. The tooling plate is configured for use with a tool to form a composite part. The group of alignment features is configured to position the tooling plate with respect to the tool used to form the composite part.
摘要:
A cone-shaped composite article may include an inner sublaminate containing at least four unidirectional plies having an inner stacking sequence with fiber angles of 0, 90, -45, and +45 degrees such that the inner laminate has a quasi-isotropic layup pattern at any location on the inner laminate. The cone-shaped composite article may also include an outer sublaminate containing at least four unidirectional plies having an outer stacking sequence that is a mirror image of the inner stacking sequence. Each one of the unidirectional plies may be continuous along a ply arclength wrapping 360 degrees around the cone-shaped composite article and may have opposing ply ends terminating at a ply seam.

The present invention relates to a method for producing a layer constructed of solar panel built up of a plurality of layers, wherein at least one layer is preheated and put together under vacuum or gas atmosphere with at least one other layer.
摘要:
A method of manufacturing curved composite structural elements can include fabricating a web ply (310) in a flat curve over a removable substrate and laying up the ply on a curved web surface of a manufacturing tool (200) . Additionally, a cap ply (402) can be laid up on one or both flange surfaces using composite tape. The structural element layup can then be inspected and any excess composite material can be trimmed away.
