Assignee:

Toyota Motor Sales, U.S.A., Inc. - Torrance CA

International Classification:

B29C 70/48
B32B 3/12

US Classification:

264511, 264257, 264258, 264259, 264263, 264313, 264314, 264317, 264324, 264571, 156245, 156286, 1563071, 1563077

Abstract:

A method for molding composite structures whereby a material stack including a core having first and second opposing sides is prepared. The preparing of the material stack includes applying a fibrous support layer on at least one of the first side and the second side of the core section, applying an adhesive layer on the support layer, and applying a thermoplastic barrier layer on the adhesive layer. The method also includes preparing a resin and a mold; placing the material stack in the mold; sealing the core; infusing the mold and material stack with resin; curing the structure; and removing the structure from the mold. In one embodiment, the method creates a composite aircraft wing panel.

Inventors:

Michael K. Maxwell - Long Beach CA, US
Richard J. Gardiner - Murray UT, US

International Classification:

B32B 3/14

US Classification:

156382

Abstract:

A system for manufacturing a molded composite structure is disclosed. In one embodiment, the system includes a first preparing component configured to prepare a material stack, wherein the material stack comprises a core section having first and second opposing sides, and wherein the first preparing component further comprises: a first applying component configured to apply first and second substantially fibrous support layers on the first side and second opposing side of the core section wherein the substantially fibrous support layers provide a vacuum path for evacuation of the core section; a second applying component configured to apply an adhesive layer on the first and second support layers and on any other surface of the core not covered by the first and second support layers; and a third applying component configured to apply a thermoplastic barrier layer on the adhesive layers covering all surfaces of the core; a second preparing component configured to prepare a resin; a third preparing component configured to prepare a mold; a placing component configured to place the material stack in the mold; an evacuating component configured to evacuate air from the core section of the material stack through the vacuum path provided by the substantially fibrous support layers; a sealing component configured to seal the evacuated core section, wherein the sealing component further comprises a first curing component configured to cure the adhesive layer to adhere the support layers and thermoplastic barrier layer to the core sections such that after sealing, the thermoplastic barrier layer prevents air from entering the core section, thereby forming an evacuated material stack; an infusing component configured to infuse the mold and the evacuated material stack with the resin to form the structure; a second curing component configured to cure the structure; and a removing component configured to remove the structure from the mold.

US Classification:

89 3602, 264 296

Abstract:

A device and process of forming a defensive, ceramic based, applique armor for covering and protecting a substrate which may be exposed to attack by projectiles, the applique armor having a flat or curved armor plate formed of ceramic material and having a first surface and a second surface; wherein the ceramic material being formed of silicon carbide with carbon fibers (C/SiC) and the ceramic material has a plurality of holes on at least one of the surfaces; the holes having a diameter smaller than an anticipated bullet or ammunition projectile and the holes being set obliquely relative to at least one surface, whereby the device and process provide holes formed by press molding, boring, drilling, or combinations thereof.
