A system for manufacturing a display unit according to an exemplary embodiment of the present invention includes: a carrying unit configured to carry an optical film including a polarizing film and a release film, wherein the polarizing film includes an adhesive layer through which, a release film adheres to and is peeled from the polarizing film; a cutting unit configured to cut the optical film up to a predetermined depth to form a polarizing film sheet piece on the optical film, without cutting the release film; a panel supply unit configured to continuously supply a panel to an attachment position, at which the polarizing film sheet piece is attached to one surface of the panel; an attachment unit configured to peel the polarizing film sheet piece from the release film, and attach the peeled polarizing film sheet piece to the one surface of the panel supplied by the panel supply unit; and a winding unit configured to wind the release film peeled by the attachment unit, wherein the attachment unit includes: an adhering means, which has an adhering property at an external side thereof, and peels the polarizing film sheet piece from the release film by the adhering property, and moves to the attachment position and makes the polarizing film sheet piece face the one surface of the panel in parallel; and an attaching means, which presses the adhering means to attaches the polarizing film sheet piece to the one surface of the panel.

Protective clothing materials and related methods and garments are provided. In some embodiments, a protective clothing material may comprise a fibrous layer that serves as a barrier to certain fluids (e.g., bodily fluids, water) and microbes. The impermeability of the fibrous layer may be due, at least in part, to the structural uniformity and/or relatively small pore size of the fibrous layer. In some embodiments, the fibrous layer may have a relatively high air permeability that imparts beneficial properties (e.g., relatively high air flow, breathability) to the protective clothing material without adversely affecting its protection rating. In certain embodiments, the protective clothing material may also comprise one or more coarse nonwoven webs that impart beneficial properties (e.g., splash resistance) to the protective clothing material. The protective clothing materials, described herein, may be particularly useful for a wide variety of applications, including the formation of AAMI level 4 protective garments.

Disclosed in the present invention is a manufacturing method for a carbon steel and austenitic stainless-steel rolling clad plate, comprising the steps of: (1) obtaining a blank material of a carbon steel layer and a blank material of a stainless-steel layer; (2) assembling blank materials; (3) cladding and rolling; (4) cold rolling; (5) first annealing; and (6) second annealing. The carbon steel and austenitic stainless-steel rolling clad plate has two unique annealing processes, so that the clad plate has the performance advantages of the austenitic stainless-steel and the carbon steel. In addition, further disclosed in the present invention is a carbon steel and austenitic stainless-steel rolling clad plate manufactured by this method.

An aerospace component may comprise a fiber reinforced composite material. The fiber reinforced composite material includes a plurality of fiber layers and a carbon matrix surrounding the plurality of fiber layers. A plurality of ceramic particles is dispersed in the carbon matrix. A first fiber layer of the plurality of fiber layers may include a carbon fiber, and a second fiber layer of the plurality of fiber layers may include a non-carbon fiber. A hardness of the non-carbon fiber is greater than a hardness of carbon fiber.
