A corner trim material that is made of a material that will bond with current industry mastics such as all purpose joint compounds, resists impact, resists abrasion, and readily accepts common coatings such as drywall mud, texture and paints. The surface of this material generally does not need to be covered by any secondary fiber based material such as paper to improve bonding or coating on the inside or outside. The material generally consists of a polymer mixed with a fibrous material like pulp or glass fiber. A corner trim piece can be directly extruded from the mix. The corner trim piece can have a center hinge, can be bullnose, and the flanges can optionally have holes or optionally be coated with adhesive.

A method for manufacturing a ballistic resistance package which includes providing a molecularly oriented tape material having a front face and back face with a minimum of two sets of parallel side faces; wrapping molecularly oriented fabric material around the front and back faces and a set of the parallel side faces of the molecularly oriented tape material, yielding a wrapped core structure; and finalizing the wrapped core structure to yield the ballistic resistance package. A multifunction ballistic resistance system for resisting projectiles and/or mitigating blast effects of explosions. The multifunction ballistic resistance system may include: at least one cellular frame defining cells therein, and a plurality of molecularly oriented tape material core structures wrapped in molecularly oriented fabric material and finalized, and attached to at least one cellular frame.

Superhydrophobic films from plastic waste and a fabrication method thereof are provided. Superhydrophobic films with variable thickness, comprising a base and top layer, can be created using semi-crystalline polymers, including virgin, recycled, or waste forms. The fabrication process utilizes 60% of total plastic waste, resulting in films with contact angles between 120? to 160?, tensile strength ranging from 1 MPa to about 70 MPa, and thickness ranging from 20 ?m to about 5 mm. Superhydrophobic films may impart protective water-repellent properties against the elements.

Superhydrophobic films can be prepared from a stream of plastic waste (i.e., derived from post-consumer and/or industrial waste) by a method comprising: dissolving first semi-crystalline polymers in a solvent to form solution1; pre-heating a solid substrate to below a boiling point of the solvent; applying solution1 onto the substrate using spin-casting to obtain a porous blended-polymer layer with fragile structure; annealing the porous blended-polymer layer to above the melting point of the first semi-crystalline polymers to strengthen the porous blended-polymer layer's internal structure by closing pores and decreasing surface roughness, thereby obtaining a strong non-porous base support layer; and dissolving second semi-crystalline polymer in a solvent to form solution2; pre-heating the non-porous base layer to a temperature below a boiling point of the solvent; applying solution2 onto the non-porous base layer to obtain a top porous layer crosslinked with the non-porous base layer; and peeling off the freestanding superhydrophobic film.

A method for manufacturing a plastic fuel tank including: a) inserting a plastic parison including two distinct parts into an open two-cavity mold; b) inserting a core, bearing at least part of a reinforcing element configured to create a link between the two parison parts, inside the parison; c) pressing the parison firmly against the mold cavities, for example by blowing through the core and/or creating suction behind the cavities; d) fixing the part of the reinforcing element to at least one of the parison parts using the core; e) withdrawing the core; f) closing the mold, bringing its two cavities together to grip the two parison parts around their periphery to weld them together; g) injecting a pressurized fluid into the mold and/or creating a vacuum behind the mold cavities to press the parison firmly against the mold cavities; and h) opening the mold and extracting the tank.
