A process for making a fibrous panel member and a flooring structure is disclosed. The flooring structure has a subfloor, a surface layer, and an insulative pad disposed between the subfloor and the surface layer. The insulative pad has an MDI binder and reinforcement fibers distributed uniformly and randomly within a first plane. The process includes mixing a porous fiber material with a MDI adhesive. The fiber batt is compressed between a pair of porous belts. Steam and heat are applied to the compressed batt to form a bound flexible batting material.

A method of manufacturing a polarizing plate according to an embodiment of the present invention includes: stretching and dyeing a laminate including a resin substrate having a long shape and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate, to thereby produce a polarizing film on the resin substrate; laminating an optically functional film on a side of the polarizing film of the laminate, to thereby produce an optically functional film laminate; and cutting widthwise direction end portions of the optically functional film laminate. The cut portions include the resin substrate, the polarizing film, and the optically functional film.

A bamboo composite material for structural applications and method of fabricating the same are provided. The method can comprise the steps of providing a bamboo culm; separating a slice or sheet from the bamboo culm such that the slice or sheet has a longitudinal axis along a fiber direction of the bamboo culm; at least partially detaching individual fiber bundles of the slice or sheet from each other along the longitudinal axis of the slice or sheet; applying a glue to the slice or sheet; and curing the glued slice or sheet.

A method of manufacturing curved composite structural elements can include fabricating a web ply in a flat curve over a removable substrate and laying up the ply on a curved web surface of a manufacturing tool. The method also can include laying up a diagonal ply with fibers oriented at +/45 from the centerline of the web surface. The method further can include cutting a unidirectional composite tape into segments and laying up the tape segments to form a cross ply with a fiber orientation normal to the centerline of the web surface. One or both edges of the diagonal and cross plies may be folded over one or two sides of the manufacturing tool to form one or two flange surfaces. Additionally, a cap ply can be laid up on one or both flange surfaces using composite tape. The structural element layup can then be inspected and any excess composite material can be trimmed away.
