20110011518 | Composite thermoplastic matrix airframe structure and method of manufacture therefore - A thermoplastic matrix airframe structure section includes a multitude of thermoplastic matrix frame members and a multitude of thermoplastic matrix beam members which form a substructure, which receives a thermoplastic matrix inner cap grid structure, a thermoplastic matrix outer cap grid structure, and a thermoplastic matrix skin which are in-situ co-bonded to the substructure to significantly strengthen and unify the substructure. | 01-20-2011 |
20120199292 | PLY LOCKING FOR HONEYCOMB PANELS - A tool for forming a panel including a core area, at which plies sandwich a core, and a trim area surrounding the core, at which the plies are bonded together, is provided and includes a body having a surface on which the panel is formable, the surface including core and trim portions for respective correspondence with locations of the core and trim areas of the panel, a border between the core and trim portions defining a surface feature displaced from a plane of the core portion, a lock disposable proximate to the surface feature to increase a pre-bonding friction between the plies at the surface feature and an assembly to apply bonding pressure to the plies and the lock at least at the core and trim areas. | 08-09-2012 |
20120204741 | CO-CURING REUSABLE ELASTOMERIC CAUL PLATE - A caul plate system for a laminate structure includes a plurality of layers of curable caul plies disposed over a laminate structure and substantially conforming to a surface of the laminate structure. A resin is applied to the plurality of layers of caul plies. Co-curing of the plurality of layers of caul plies with the laminate structure hardens the plurality of layers of caul plies such that a normal pressure is applied to the laminate structure during cure of the laminate structure. | 08-16-2012 |
20120255676 | EXTERNAL TO BAGGING MECHANICAL CLAMP - A tool for forming a panel including a core area, at which plies sandwich a core, and a trim area surrounding the core, at which the plies are bonded together, is provided and includes a body having a surface on which the panel is formable, an assembly to apply bonding pressure to the plies at least at the core and trim areas and a clamping device external to the assembly to apply a clamping force to the vacuum bag and the plies. | 10-11-2012 |
20120276362 | FAY SURFACE SEALANT APPLICATION - A method of sealing between two components includes applying and curing a layer of fay surface sealant to a first component. A layer of liquid shim is applied to one or more of the first component and a second component. The first component is assembled to the second component with the layer of fay surface sealant and the layer of liquid shim therebetween. An assembly of two components includes a first component and a layer of fay surface sealant applied and cured to a first facing surface of the first component. A second component includes a second facing surface, such that the second facing surface and the layer of fay surface sealant define a gap therebetween. A layer of liquid shim is located between the second component and the layer of fay surface sealant thereby substantially filling the gap. | 11-01-2012 |
20150093541 | COMPOSITE STAPLE - A laminate design is provided and includes a substrate formed to define through-holes, an initially uncured pre-preg laminate disposed proximate to the substrate and an initially uncured pre-preg staple. The staple includes a main member and legs extending from the main member and being disposable with the legs extending through the through-holes to pierce the laminate. The staple is co-curable with the laminate. | 04-02-2015 |
20150133016 | IMPACT RESISTANT COMPOSITE PANEL AND METHOD OF FORMING A COMPOSITE PANEL - A composite panel includes a support layer including a first plurality of prepreg plies wrapped around at least one mandrel; a mid-plane impact layer including a second plurality of prepreg plies, the mid-plane impact layer adjacent to the support layer; a upper skin layer including a third plurality of prepreg plies, the upper skin layer adjacent to the mid-place impact layer; and a lower skin layer including a fourth plurality of prepreg plies, the lower skin layer adjacent to the support layer; whereby each of the first, second, third, and fourth plurality of prepreg plies are co-cured to form the composite panel. | 05-14-2015 |
20150136308 | FIELD REPAIR KITS FOR STRUCTURAL PANEL - A kit for repairing an opening formed in a composite panel having a laminate skin arranged on opposing sides of a first core material is provided including a plug and a patch. The plug is formed from a second core material and has a cured filler material arranged within at least a portion of the second core material. The patch is formed from a plurality of cured first plies arranged in a stacked orientation. The plug is configured to be received within the opening of the composite panel and the patch is configured to cover the opening of the composite panel. | 05-21-2015 |
