Abstract: A degradable cleaning assembly (300) which is formed from a plurality of substantially identical layers (10) of a food starch, wherein the layers (10) are coupled together. Particularly, the coupled layers (10) cooperatively form an assembly (100) which is then permitted to soak in a glycerin and soap additive material (250), removed from the material (250), and allowed to solidify, thereby forming the degradable cleaning assembly (300) which selectively degrades or dissolves when exposed to water for a certain amount of time.

Abstract: A method 10 to selectively produce an article of manufacture 20 having desirable properties and which may replace many “ceramic based” articles. Particularly, the article of manufacture 20 is made by selectively combining an epoxy structural foam material 110 with a catalyst 111 and a drying agent 200. The mixed material is then selectively dispensed within a mold 16 and allowed to harden in order to form the article of manufacture 20. Alternate formulations may be utilized. Other various non-limiting embodiment of the invention are also disclosed.

Abstract: A member (10), a support insert (126, 216), a method for forming member (10), and a method for stiffening a member (10) by use of support insert (126, 216). Member (10) includes a foam material (16) which is attached to the member (10) by the use of a layer of polyurea material. These layers cooperate to rigidize the member (10) and reduce the noise generation and transmission attributes of the member (10).

Abstract: An assembly 10 and a method 200 which utilizes the assembly 10 to selectively and structurally strengthen and rigidize and/or stiffen a member 150 which is operatively disposed within an article of manufacture, such as an without limitation, a vehicle. Particularly, the assembly 10 includes a selectively expandable portion 18 which is stretched along an inflation wand 12 and is then inserted into the member 150 via a relatively small aperture 155 formed within the member 150. Selectively expandable portion 18 is then inflated with a material 52 to support the member 150.

Abstract: A two-part for reinforcing a hollow strucutral members and its method of use are provided. A method of reinforcing a structural member having a hollow cavity comprises the steps of preparing a first dough which includes a thermal setting resin, a first filler and unexpanded, thermally-expandable microspheres. A further step includes preparing a second dough which includes a curing agent, a colorant and a second filler. The curing agent is compatible with the thermosetting resin to promoter cross-linking of the thermosetting resin upon contact with the curing agent. The hollow structural member may be preheated to enhance the rate at whcih the thermosetting resin cross-links. The two dough are blended together until a reactive third dough of substantially uniform mixture is formed. The uniformity of the blending is confirmed when the reactive third dough attains a uniform color intermediate the color between the colors of the first and second doughs.

Abstract: A two-part system for reinforcing a hollow structural member and its method of use are provided. Part A of the two-part system is formed by adding a filler and unexpanded, thermally-expandable microspheres to a liquid thermosetting resin, such as an epoxy resin, in a quantity sufficient to produce a dough-like mass which can be readily kneaded. Part B is formed by adding a filler and a colorant, such as carbon black, to a liquid curing agent, again forming a dough-like mass. The curing agent is compatible with the thermosetting resin to promote cross-linking of the thermosetting resin upon contact with the curing agent.A hollow structural member is cleared of debris of the like and may be preheated to enhance the rate at which the thermosetting resin cross-links. The two parts are blended together until a reactive third dough of substantially uniform mixture is formed.

Abstract: A lightweight, composite beam for reinforcing a vehicle door is provided. The reinforcing beam comprises an open channel-shaped metal member having a longitudinal cavity which is filled with a reinforcing polymeric material which in one aspect is a thermoset or thermoplastic resin-based material. The composite beam includes end pieces which are adapted to be mounted to a vehicle door panel in a door cavity by spot-welds or the like. The horizontally mounted beam provides substantially increased resistance to side impacts to the vehicle door in the event of a collision. In one embodiment, the beam is mounted between the window glass space and the inner door panel for flush-glass vehicle doors. In another configuration, one surface of the beam is sculptured to mate with a concise outer door panel.

Abstract: A hollow torsion bar reinforced by a mixture of resin and filler and method of making such a torsion bar. The torsion bar is formed from mild or medium grade steel seamless or welded tubing. The tubing is cut to length and charged preferably with a mixture of substantially uncured thermoset resin and plastic or glass hollow microspheres and/or metal pellets. The mixture may be charged into the tube by injection as a paste or by placing inside the tube a B-staged form insert having preferably between about 10 and 50 percent elongation tensile strength. After the tube has been charged with the reinforcing mixture, the tube is bent to form a torsion bar having a radius arm and a spring portion. In areas that the torsion bar is bent, the reinforcing mixture is provided to act as an internal mandrel preventing collapse of the tube walls. The mixture is then cured and bonded in place by chemical reaction of the resin or by thermally curing the resin mixture within the tube.

Abstract: The method of the present invention includes mixing a low viscosity thermoset resin and microspheres together without melting the thermoset resin and extruding the mixture to form a continuous strand of paste-like uncured material. The continuous strand is gelled on a conveyor which preferably includes a radiant heater or other means for accelerating the gelling of the continuous strands into solid form. The strands are then cut or chopped into pellet form and may be coated with an adhesive or B-staged material in preparation for forming into structural reinforcements. The pellets are filled with microspheres in the amount of 20 to 35% of resin weight. The pellets may include unexpanded thermally expandable microspheres which permit expansion of the pellets when exposed to heat to provide a pellet having a bulk density as low as 9 pounds per cubic foot.
