Sandwich composite constructions with superior thermal and acoustic insulation properties are provided. In addition, the sandwich composite constructions are lightweight and have a mechanical integrity that may allow them to withstand an impact force of five pounds per square inch or more. One aspect of the present invention relates to the composition of the sandwich constructions, while another relates to methods of fabricating the sandwich composite constructions. Materials incorporated into the constructions include fibrous material, aerogel, resin, separation material, and insulating material, such as a foam. A vacuum assisted resin transfer method (VARTM) may be used to manufacture the sandwich composites by infusing resin into a composite preform such that the resin is received into at least a portion of the fibrous material pores. Water soluble tooling materials may be used as the substrate for the preform to fabricate sandwich composite panels having either simple or complex geometries.

A design for a high damping composite joint which dissipates vibrations through the use of air gaps and viscoelastic material minimizing the transfer of vibrations to the metallic coupling. Viscoelastic material is used with adhesive to provide for increased energy dissipation by the joint. As the load increases on the joint, the load transfers from adhesive to the viscoelastic. The viscoelastic begins to take the load of the joint at the point where the adhesive becomes plastic. Acoustic vibrations are then dissipated in the viscoelastic and are prevented from being transferred to the metallic coupling by air gaps provided in the joint. The amount of viscoelastic and adhesive used depends on the anticipated load. Finite element analysis is used to calculate optimal amounts of viscoelastic and adhesive.

A process for continuous composite coextrusion comprising: (a) forming first a material-laden composition comprising a thermoplastic polymer and at least about 40 volume % of a ceramic or metallic particulate in a manner such that the composition has a substantially cylindrical geometry and thus can be used as a substantially cylindrical feed rod; (b) forming a hole down the symmetrical axis of the feed rod; (c) inserting the start of a continuous spool of ceramic fiber, metal fiber or carbon fiber through the hole in the feed rod; (d) extruding the feed rod and spool simultaneously to form a continuous filament consisting of a green matrix material completely surrounding a dense fiber reinforcement and said filament having an average diameter that is less than the average diameter of the feed rod; and (e) depositing the continuous filament into a desired architecture which preferably is determined from specific loading conditions of the desired object and CAD design of the object to provide a green fiber reinforced composite object.

Mesh susceptors for use in induction heating and bonding processes are tailored to obtain more uniform heating across the susceptor and hence, the bondline, when bonding composite parts. The susceptors are tailored by cutting and removing segments from the mesh areas where the induced current and hence, heat generation, is highest. An algorithm is employed to predict the induced current patterns throughout the mesh so that areas of high heat generation can be identified and then cut and removed. In this way, essentially uniform temperatures in metal mesh susceptors may be achieved by specifically designed cut patterns within the mesh even though the mesh susceptor is subject to non-uniform magnetic fields.

A method and apparatus for forming laminate composite structures. At least two laminae, each containing electrically conductive reinforcing fibers, are placed upon each other in contacting relationship to form a generally layered structure. The layered structure may be subjected to heat to conductively transfer heat through the layered structure and thereby improve the surface contact between the two laminae. The layered structure is volumetrically heated by inductively transferring energy to the electrically conductive reinforcing fibers. The heated, layered structure is consolidated, such as by applying pressure and reducing the temperature of the layered structure. The consolidated structure is then quenched by rapidly cooling the consolidated structure in a directionally controlled manner about a midplane thereof.

A composite carbon fiber material is formed of one or more layers of carbon fiber material in which the carbon fibers are aligned all in the same direction and a mat of nonwoven, woven, or off-axis unidirectional carbon fibers are laminated together. Layers may be used individually or as a hybrid. The layers can be preimpregnated or impregnated during processing using thermoplastic or thermosetting resins. A layer of thermoplastic resin is applied either over the surface or within the composite structure, and the resin permeates the material so as to provide a more stable mechanical structure once the resin is processed. The material combines good mechanical strength with improved electrical current carrying properties when compared with the aligned carbon fiber layer alone. The layering sequence, layer type, and resin type can be specified to tailor electrical properties, mechanical properties, durability, and wear resistance. The resultant material achieves these results in substantially smaller material thickness than previously available.

The invention is drawn to a nozzle device for gas torches which allows interactive, real-time control of thermoplastic processing and a method of using this device. The device consists of a movable nozzle slide that it attached to the tip of the torch. The nozzle slide can be moved in an upward or downward direction, thereby changing the amount of heat contacting the material.

Multiple resin transfer molding is the simultaneous injection of differing esins in fiber preforms with or without a separation layer. The flow of the resins is controlled by varying the permeabilities of the preforms and the separation layer. The method produces multifunctional hybrid composites made of multilayered preforms and multiple resins. A fundamental advantage of the invention is the simplification of the manufacturing process.
