Flexible, fibrous energy managing composite panels

A flexible, fibrous energy managing composite panel includes multiple flocked energy absorbing material (FEAM) layers separated by dividers. The FEAM layers can be single side or double side and can be fabricated from monofilament fibers having different properties (e.g., length and denier) flocked onto various substrates. The dividers can include sheets, fabrics, films, foam, spacer fabrics to separate the flock fibers in adjacent layers. The composite panels can be processed for breathability and flexibility. Other embodiments include piezoelectric FEAM layers and dividers for electronic sensing applications, and application of composite panels to body armor and the outer shells of helmets.

Process and system for making an erosion control mat
11198231 · 2021-12-14 · ·

A process for making an erosion control mat includes rotating a cylindrical drum having a plurality of mold cavities; depositing a paste into the mold cavities; selecting the sheet of mesh material to have sufficient tensile strength to join the blocks of hardened paste together without tearing or separating from the blocks of hardened paste, and to have sufficient density to retain the paste within the mold cavities as the drum rotates; covering an outer surface of the cylindrical drum and outer surfaces of the paste with the sheet of mesh material; continuing to rotate the cylindrical drum as the paste hardens into dimensionally stable blocks, and holding the sheet against the outer surface such that the sheet retains the paste within the mold cavities and the sheet becomes embedded in the paste; and separating the dimensionally stable blocks from the mold cavities.

A METHOD TO MAKE BICOMPONENT FIBERS AND ARTICLES COMPRISING THE SAME
20230257909 · 2023-08-17 ·

The disclosure generally relates to bicomponent fibers, and more particularly, methods to make bicomponent fibers and articles comprising them, wherein a first extruded component has a moisture level less than a second extruded component. The bicomponent fibers may comprise polyesters and are useful in articles such as carpets and fabrics.

Composite sheet material
11167524 · 2021-11-09 ·

A method of forming a composite sheet material, the method comprises energising a pair of electrodes to apply an electrostatic charge to a bed of fibres located therebetween thereby orienting at least some of the fibres to be substantially orthogonal to the electrodes and sandwiching at least some of the oriented fibres between a first sheet and a second sheet. The first sheet may be subsequently removed. A third sheet may be used to sandwich the fibres between the second sheet and the third sheet. Apparatus (100) is disclosed for carrying out the method.
