A method of preparing a woven fabric material for use in a ceramic matrix composite includes passing a desized woven fabric tape having a first inter-filament spacing through a dispersal module configured to transform the desized woven fabric tape into a dispersed woven fabric tape having a second inter-filament spacing greater than the first inter-filament spacing. The dispersal module includes a first charging element with a charged surface and disposed to apply an electric charge to the desized woven fabric tape. The method further includes applying a polymer binder to the dispersed woven fabric tape to create a stabilized woven fabric tape having the second inter-filament spacing.

A composite scaffold having a highly porous interior with increased surface area and void volume is surrounded by a flexible support structure that substantially maintains its three-dimensional shape under tension and provides mechanical reinforcement during repair or reconstruction of soft tissue while simultaneously facilitating regeneration of functional tissue.

A sleeve for protecting an elongate member, including a bus-bar of a battery pack, and method of construction thereof are provided. The sleeve includes a knit wall having a circumferentially continuous outer surface extending along a longitudinal axis between opposite open ends. The knit wall is formed at least in part by multifilament flame-resistant yarn. The multifilament flame-resistant yarn is knit to form both the knit wall, and also first ribs extending lengthwise along the circumferentially continuous outer surface or second ribs extending annularly about said circumferentially continuous outer surface. An impervious, flame-resistant coating is bonded to an outer surface of the circumferentially continuous knit wall.

A preparation method for producing a light-transparent artificial leather comprises the steps of: mixing, stirring, grinding, filtering and defoaming primary raw materials, including toner with a particle size of 0.5˜10 nm, polymer powder and a plasticizer, to produce a light-transparent pigment; mixing the light-transparent pigment with secondary raw materials, including polymer powder, a plasticizer, a stabilizer and an inorganic additive, and stirring, grinding, filtering and defoaming the mixture to produce a light-transparent epidermal layer material; mixing a base fabric, glue and a support layer material with the epidermal layer material and making the mixture into a semi-finished artificial leather product, which comprises the light-transparent epidermal layer, a support layer, a glue layer and a base fabric; and applying a surface treating agent on to the surface of the light-transparent epidermal layer to produce a light-transparent artificial leather (e.g., for an automobile interior).
