Abstract: In the manufacture of lightweight structural profile including a resin-bonded core of closely compacted particulate filler, loose filler is packed into a shaping die by means of applied vacuum. The filler is packing within a sheath of glass rovings which is used to draw the packed filler through the die. As the sheath and packed filler are progressed through the die, a liquid bonding resin is introduced to permeate and bond together the packed filler and the sheath. The filler includes layer mineral foam in a coarse particulate form and a free-flowing relatively fine material (such as hollow silicate microspheres) as an additional filler, the additional filler being vacuumed in to occupy the interstices of previously packed foam filler.

Abstract: A cylinder, for example a lickerin, and feed mechanism create a supply of individual fibers, for example pulp, which follow the rotation of the lickerin. These fibers are deflected from the lickerin in the form of a stream by means of a plate arranged parallel to the lickerin. A conveying screens intercepts the stream of fibers and accumulates them into a web without the use of a high pressure stream of air to doff the fibers from the lickerin or to capture fibers on the conveyor. Further, the housing for the apparatus is opened so that there are no seals to compress the web after it is produced. A feed tray located next to the lickerin can be used to include other particulate materials (fiber or granules) in the main fiber stream and a tapering of the deflector plate can separate the component of the blended fiber-particulate material stream into layers in the resulting web distinguished by particle weight.

Abstract: An apparatus for consolidating sheets (13) of continuous graphite fiber in a thermoplastic matrix resin uses a roller (10) in conjunction with a heating surface (16) and a vacuum bag (12). A tack-welded stack of composite sheets (13) or prepreg is assembled onto a frame support structure (27) and placed into the vacuum bag (12) as an assembly (28) which is placed on a heated surface (16) whereby its temperature is elevated above the melting point of the matrix resin in the composite sheets (13).

Abstract: Sailboards having a tucked rail are made from a flexible, resilient mold so that the seam of the board is along its bottom edge instead of at its point of greatest breadth. A flexible mold part having the contour of the sailboard to be produced has an opening smaller than the greatest breadth of the board.

Secondly, the blank is inserted into the flexed mold, and thirdly, the mold is released and its resiliency returns it to its original shape. A conventional rigid mold part closes the open end, and a vacuum is applied to form the final product. The flexible mold part is flexed a second time to remove the product.

Abstract: The vessel portion of a gas-tight container suitable for packaging fresh foods is produced as a composite of paperboard and polymer film. A pair of folded paperboard blanks, pre-cut and pre-formed, are inserted into the opposite halves of split mold elements to a blow molding machine. Vacuum orifices in each mold half unit temporarily secure the position of a respective paperboard blank. The paperboard lined mold halves are closed upon a hot, extruded parison of malleable polymer leaving an end portion of the parison tube projecting from the closed mold unit. A fluid conducting needle penetrates this projected end portion to inflate the parison with an appropriate blowing gas. Such inflation expands the malleable polymer, seamlessly and creaselessly, into the internal corners and crevices of the folded paperboard blanks. Following chilling, the mold unit is opened and the pair of paperboard flanks are ejected as a singular unit, joined by a molded flange portion of the continuous polymer film.

Abstract: An apparatus is disclosed for the shaping of a sheet of preform material. A flat planar (heated) sheet of preform material is held tightly between two elastomeric sheets of the apparatus, the sheets and preform material forming a laminate assembly.

Wrinkles are eliminated in the final shape of the preform material, and fiber distortion or tears or rips in the material are minimized due to the fluid lubrication between the mold surface and the laminate assembly.

Abstract: A vacuum bag autoclave type procedure for curing layers of phenolic resin pregnated fibrous material to form a composite structural part. A straight up heat rise cure cycle is employed in conjunction with a layup and bagging procedure that ensures a relatively free bleed of excess resin during cure and a high-capacity vacuum system for removal of volatiles generated during cure. This method of fabrication releases the majority of volatiles prior to gelation and produces a part having a pore structure that provides an escape path for gases generated during cure and postcure to prevent delamination.
