Patent number: 5352529Abstract: A thrust vectoring panel which is a hybrid ceramic/ceramic composite consisting of three layers of lightweight materials, the anisotropic properties of which are manipulated such that the properties of the materials, i.e., the coefficient of thermal expansion, the strain energy release rate, and the tensile and flexure modules, either match or gradually transition from material to material. The three layers include a face layer which is of a high temperature capable material that can withstand temperatures within a range of 2300.degree.-25000.degree. F. for an extended period of time and a temperature as high as 28000.degree. F. for a short period of time. The middle layer simply is an insulating layer for providing adequate thermal insulation for the activator mechanism for the thrust panel. The third layer is a skeletal structure or layer which is of a lightweight material having sufficient strength to support all the integral interfaces, such as the activator mounts and the like.Type: GrantFiled: March 3, 1993Date of Patent: October 4, 1994Assignee: Auto-Air Composites, Inc.Inventors: John F. Scanlon, Gary Wigell

Patent number: 5252160Abstract: A hybrid metal/composite spinner cone used in aircraft applications and a method of manufacturing the same. The spinner cone has a metal outer shell which is bonded during the molding process to an inner structural member of thermoplastic composite. The metal shell imparts several desirable characteristics to the spinner cone such as impact resistance, erosion resistance, appearance, and supplying a lightning strike material to protect the composite structure. The thermoplastic composite has significant property advantages over metal or thermoset systems. The hybrid metal/composite spinner cone is manufactured using a ceramic mold which is less expensive and more readily available than a steel mold. The metal shell provides a barrier between the thermoplastic composite and the ceramic mold and allows the finished spinner cone to be easily released from the mold.Type: GrantFiled: November 15, 1990Date of Patent: October 12, 1993Assignee: Auto Air Composites, Inc.Inventors: John F.

Patent number: 5049342Abstract: A method of fabricating a composite structure having at least one skin molecularly bonded to a core. A skin is provided of reinforcing fibrous material and a thermoplastic matrix. The skin is thermoformed to the general exterior shape of the composite structure. A core having a thermoplastic matrix complementary to the matrix of the skin is molded into the general shape of the composite structure. The skin and the core are placed in juxtaposition in a final forming mold. A thermoplastic material is injected into the final forming mold under isostatic conditions. The thermoplastic material is complementary to the thermoplastic matrices of the skin and the core.Type: GrantFiled: May 9, 1990Date of Patent: September 17, 1991Assignee: Sundstrand CorporationInventors: John F.

Patent number: 4834616Abstract: A self-locking retention system is provided for a composite rotor blade supported on a rotor hub. A radially extending, stud-like retention member is provided on the rotor hub. A composite thickness projects radially inwardly from the rotor blade and substantially surrounds the retention member. The composite thickness is woven in a pattern which grips the retention member in response to outward forces applied to the rotor blade and the woven composite thickness.Type: GrantFiled: May 30, 1986Date of Patent: May 30, 1989Assignee: Sundstrand CorporationInventors: James L.
