The purpose of the present invention is to further enhance the strength of a manufactured composite structure by further suppressing the occurrence of wrinkling. A method for manufacturing a composite structure, the method comprising: a lamination step for layering a plurality of fiber sheets and molding a plate-form laminate; a forming step for forming a recess formed by a curved surface in a prescribed portion of the laminate; a short-direction deformation step for deforming the laminate in the short direction thereof after the forming step to configure a long-direction cross-section of the laminate in a prescribed shape; and a long-direction deformation step for deforming the laminate in the long direction after the forming step, so that the recess formed in the forming step deforms, to configure a short-direction cross section in a prescribed shape.

The present invention provides methods for preparing the nut waste pot composites from a nut waste component, one or more binders, and an oil using a compounder/extruder.

In one embodiment, the microporous film has a ratio (F.sub.B/F.sub.A) of a dynamic friction coefficient F.sub.B of the surface B to a dynamic friction coefficient F.sub.A of the surface A of 1.2 to 20. In another embodiment, the microporous film is a single layer having a thickness of 3-18 μm, a number N.sub.A of pores on the surface A is 10-100/μm.sup.2, a number N.sub.B of pores on the surface B is 20-200/μm.sup.2, and N.sub.A/N.sub.B is 0.2-0.96. In addition, a total area S.sub.A of pores on the surface A is 0.02-0.5 μm.sup.2/μm.sup.2, a total area S.sub.B of pores on the surface B is 0.01-0.3 μm.sup.2/μm.sup.2, and S.sub.A/S.sub.B is 1.1-10. Furthermore, in another embodiment, a number W.sub.B of protrusion-like bodies on the surface B is 0.2-1000/100 μm.sup.2.

A method for manufacturing a fiber-containing sheet. In extruding resin into sheet form using a T-die, the extrusion from the T-die is performed with a first resin for forming a core layer and a second resin for forming both skin layers on both sides of the core layer laminated together. The first resin contains fiber material and the second resin does not contain fiber material.

A structural insulation sheathing (SIS) comprises: a first upper facial member, a second lower facial member and an insulation member in intimate, planar contact with both the first upper member and second lower members. The first and second facial members are made from the same reinforcing fiber material less than about 3/16 inch thick. The insulation member comprises a foam layer, said structural insulation sheathing having at least 10×, preferably 15 to 20 times greater strength than its individual components.

A method of manufacturing sheeting is provided, the method including the steps of forming multiple recesses in a symmetrical repeat pattern on a sheet of material, extruding a molten material to form an upper outside wall and a lower outside wall, interposing the formed sheet between the upper outside wall and the lower outside wall, and fixing the interposed sheet to the upper outside wall and the lower outside wall. Also provided is sheeting having an upper outside wall and a lower outside wall and an interposed sheet fixed between the outside walls. The interposed sheet includes multiple recesses in a symmetrical repeat pattern, where the upper and lower outside walls are, or the interposed sheet is, manufactured from a material which includes a polymeric material.

An adjustable distributor apparatus (10) for dispensing a foam forming mixture comprising a main body (20) and adjustment plate, the main body featuring at least one inlet, one channel, and one outlet, the inlet, channel and outlet in fluid connection such that a fluid may pass through the inlet into the channel and exit from the channel through the outlet, and the outlet being coupled with at least one adjustment plate (40), the adjustment plate featuring at least a first face, a second face opposing the first face, and an outlet hole, enabling a seal between either the outlet of the main body or the second face of a second adjustment plate, and the outlet hole extending from the first face to the second face by way of a fluid connection through the adjustment plate.

A forming mold for making polyvinyl chloride foamed wood-like slats includes an inlet, an outlet, and two main flow passages symmetrically arranged with respect to a central axis. The main flow passages each have an inlet section respectively connected to the inlet and an outlet section respectively connected to the outlet. The extension direction of the inlet section of each main flow passage respectively defines with the central axis an included angle therebetween. The sum of the angles of the two included angles ranges from 44.2 to 48.8 degrees. The width of the main flow passages gradually increases from the inlet toward the outlets. The height of the main flow passages gradually reduces from the inlet toward the outlets. In this way, the forming mold of the present invention can effectively improve production efficiency and can increase the stability of the product manufacturing process.

The present invention relates to a method for continuously manufacturing UHMWPE products comprising:—providing a counter-rotating twin-screw extruder;—feeding UHMWPE powder into a hopper of said counter-rotating twin-screw extruder;—transporting said UHMWPE powder from said hopper through said counter-rotating twin-screw extruder to an outlet of said counter-rotating twin-screw extruder;—further transporting said UHMWPE powder from said outlet of said counter-rotating twin-screw extruder to an entrance of a heat-controlled tooling system for defining the shape of UHMWPE products;—withdrawing said UHMWPE products from an outlet of said heat-controlled tooling system.
