The present invention relates to a photovoltaic module backsheet, comprising photovoltaic module backsheet comprising, in order: a functional layer; a connecting layer; and a weather-resistant layer, wherein each layer of the backsheet comprises at least 50 wt. % polyolefin and the backsheet is free of fluorinated polymers, characterized in that: i) the functional layer comprises a blend of polyethylene and a polyethylene copolymer; and ii) the weather-resistant layer comprises polypropylene; a UV stabilizer; a primary antioxidant, which primary antioxidant is a phenolic antioxidant or an aromatic amine antioxidant; and secondary antioxidant, which secondary antioxidant is a trivalent phosphorus containing antioxidant or a thioether containing antioxidant. The present invention also relates to a process for producing the backsheet and a photovoltaic module comprising the backsheet according to the present invention.

One aspect of the present invention provides a composite sheet which comprises a nitride sintered body having a porous structure and a semi-cured product of a thermosetting resin composition impregnated into the nitride sintered body, the line roughness Rz specified by JIS B 0601:2013 of at least one main surface being 10 μm or less.

The present disclosure relates to a prepreg, a preparation method thereof and a fiber-reinforced composite material prepared therefrom. The preparation method of a prepreg may include an aramid fiber base material with improved wettability to resin, can increase a thickness reduction rate during molding of the prepreg, has an appropriate resin content, and can provide a prepreg suitable for molding by an out-of-autoclave process. In addition, the prepreg may provide a fiber-reinforced composite material that exhibits a thin thickness and a high resin content even by an out-of-autoclave process, and shows high strength and low moisture absorption

A fiber-reinforced polymer composite assembly, that includes a plurality of sheets, each formed from a composite mixture including a fibrous material and a resin, wherein each of the first plurality of sheets are cut to one or more predetermined dimensions. The plurality of sheets are configured to form a stack, and wherein the stack is shaped by positioning the stack on a mold and pressing and consolidating/curing the stack to form a doubly-curved geometric shape. An insert may be positioned between the plurality of sheets, prior to the pressing and consolidating/curing, wherein the fibrous material may in include paper, and wherein the resin includes one of a thermoset resin or a thermoplastic resin.

An engineered wood based siding, cladding or panel with a pre-consolidated fines layer (PCF) applied to the top of the main strand matrix layers to minimize telegraphing and provide an improved surface appearance. The PCF is consolidated prior to application to the surface of the strand matrix or mat, and takes the place of a loose fines layer. The PCF prevents the loss of fines into the strand matrix, effectively keeping the fines at the surface so they can effectively and efficiently function to prevent or eliminate strand telegraphing, and provide a smooth finished surface for the product.

The present disclosure relates to a multilayer composite that may include a first barrier layer and a first foam layer. The first foam layer may include a polyurethane-based matrix component, and a flame retardant filler component. The multilayer component may also have a HBF flammability rating as measured according to ASTM D4986.

A multi-layer ballistic woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The multi-layer ballistic woven fabric also includes a lower woven layer having lower warp yarns and lower weft yarns that are interwoven together, and a plurality of securing yarns, each securing yarn interwoven with at least some of the upper yarns and some of the lower yarns so as to secure the upper and lower woven layers together. At least one of the securing yarns is woven underneath a first lower weft yarn, then above a second upper weft yarn adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. The multi-layer ballistic woven fabric is formed by interweaving the securing yarns with the warp yarns and weft yarns as the upper woven layer and lower woven layer are made.

The present application discloses improved lignocellulosic composite materials comprising a lignocellulosic component, a bis-electrophile, and a polynucleophile. Exemplary embodiments comprise a dianhydride and a polyol.
