20210101735 · 2021-04-08 ·

A method of forming a shipping container includes mixing paper fibers with a binder fiber to form a mixture; disposing the mixture onto a surface to form a layer of the mixture; applying heat to form a paper fiber batt from the mixture having a fixed width and fixed length; and inserting the paper fiber batt within an interior of a corrugated box.

Method of making an insulation material and an insulated mailer

A method and system for producing an insulated mailer and an insulated box having an insulative paper fiber pad substructure with a density of less than about 10 pounds per cubic foot. The insulative paper fiber pad has entangled reinforcement fibers. A method of forming an insulative paper fiber pad using recycling-compatible or water soluble adhesive and paper layers is provided.

FIBER REINFORCED MATERIALS WITH IMPROVED FATIGUE PERFORMANCE
20210069995 · 2021-03-11 ·

A fiber-reinforced fabric, composite materials formed from such fabrics, and methods of making the fiber-reinforced fabric or composite materials, are provided. The fabrics and composite materials demonstrate improved fatigue performance relative to conventional fiber-reinforced fabrics.

Laminate and method of making same

A laminate is made by first non-crimping or low-crimping continuous filaments to form a first spunbond layer and preconsolidating the first spunbond layer with a heated or calendering roller. Then continuous filaments with a greater crimp than the continuous filaments of the first spunbond layer are deposited as a second spunbond layer over the first spunbond layer to create a two-layer structure. Finally, the two-layer structure of the first and second spunbond layers is consolidated such that a total thickness of the laminate is 0.15 to 3 mm, preferably 0.2 mm to 2.5 mm and especially 0.2 mm to 2 mm.

SYSTEM FOR PRODUCING CHOPPED ROVING THERMOPLASTIC COMPOSITE SHEETS
20210001599 · 2021-01-07 ·

A chopped roving thermoplastic composite sheet includes a web or mesh of chopped rovings and a thermoplastic resin that fully saturates the web or mesh of chopped rovings. The web or mesh of chopped rovings is not mechanically bonded and does not include a binder that bonds or adheres the chopped rovings together other than thermoplastic resin. As such, the thermoplastic resin and the web or mesh of chopped rovings are able to flow and conform to a mold or cavity when the chopped roving thermoplastic composite sheet is pressed within the mold or cavity and when the chopped roving thermoplastic composite sheet is heated to above the melting temperature of the thermoplastic resin.

Repulpable container

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

Methods of forming repulpable containers

A method of forming a shipping container includes mixing paper fibers with a binder fiber to form a mixture; disposing the mixture onto a surface to form a layer of the mixture; applying heat to form a paper fiber batt from the mixture having a fixed width and fixed length; and inserting the paper fiber batt within an interior of a corrugated box.

Continuous sheet press and method of operating same

A press for making a continuous sheet from composite material has upper and lower press belts having respective lower and upper reaches that vertically spacedly confront one another across a press gap having an upstream inlet end and a downstream outlet end, and that have transversely spaced outer edges extending in the direction. The belts are advanced direction and thereby draw a mat of the composite material in the inlet end, compress it into the sheet, and expelling the sheet from the downstream end. Two transversely spaced elastic seal strips extend in the direction in the gap and are each engaged between a respective one of the outer edges of the upper belt and the respective outer edge of the lower belt. Each belt has at each of the edges a surface in engagement with the respective edge strip and having an average peak-to-valley height of less than 1 m.

Apparatus for manufacturing fiber reinforced resin material

An apparatus for manufacturing a fiber reinforced resin material, by cutting long fiber bundles into a plurality of pieces having a predetermined length, and impregnating the cut fiber bundles with resin, includes a plurality of cutters each having a predetermined length and configured to cut the long fiber bundles, and a conveyance unit provided below the cutters and configured to continuously convey the fiber bundles cut with the cutters. The cutters are arranged along a conveying direction of the conveyance unit, such that respective longitudinal directions of the cutters form different angles with the conveying direction of the conveyance unit, when viewed from above the cutters.
