The present disclosure generally relates to carbon fiber reinforced polyolefin compositions, which may have a relatively low density. The compositions may include a thermoplastic olefin, a filler component, a compatibilizer, and/or an additive package. In some embodiments, the filler component includes a plurality of carbon fibers. In addition, articles of manufacture and methods of making a carbon fiber reinforced polyolefin composition are provided.

Carbon fiber reinforced polyolefin compositions and methods

Low density polyolefin compositions with improved stiffness, impact balance, and high dimensional stability are described. These compositions are useful for making automotive components, such as injection molded parts, as well as other articles of manufacture. The compositions comprise (a) a polyolefin comprising polypropylene, a propylene-ethylene block copolymer, or combinations thereof, wherein the polyolefin blend is present in an amount ranging from about 55 wt. % to about 72 wt. %; (b) a first elastomer and a second elastomer that are not the same, wherein the combined weight percent of components (b) ranges from about 18 wt. % to about 33 wt. %; (c) a filler present in an amount ranging from about 6 wt. % to about 12 wt. %; and (d) an additive package present in an amount ranging from about 0.5 wt. % to about 5 wt. %, all wt. % are based on the total weight of the composition.

Low density polyolefin resins with stiffness, impact balance, and high dimensional stability

The present invention is directed towards an article suitable for attachment to facial skin or other surfaces, which comprises microfibrils and continuous microribbons. The article provides good sealing when used on a regular skin, and on a challenge skin surface with facial hair, sweat and acnes. The article also provides good adhesion and sealing on any other rough surfaces, and can be used repeatedly against different surfaces. These dry adhesives can be used for improving sealing of mask respirators, swimming goggles, or for other applications such as medical bandage, working gloves, and protective clothing seal.

Micropatterned structures for forming a seal with the face skin and other surfaces and method of make

Methods involve a combination of polyelectrolyte multilayer (PEM) coating or silane self assembly on a substrate; microcontact printing; and conductive graphite particles, especially size controlled highly conductive exfoliated graphite nanoplatelets. The conductive graphite particles are coated with a charged polymer such as sulfonated polystyrene. The graphite particles are patterned using microcontact printing and intact pattern transfer on a substrate that has an oppositely-charged surface. The method allows for conductive organic patterning on both flat and curved surfaces and can be used in microelectronic device fabrication.

Micropatterning of conductive graphite particles using microcontact printing

The present invented mechanism comprises more than two (legs) with phase difference (like polygon-shape, ellipse-shape, and etc) between their rotation angles to produce pre-loading for improved adhesion. Two rigid plates covered with adhesives are attached to each phase difference wheel. Each plate connects to the wheels via a hinge embodying a torsional spring, which forces the plate back to its original position after each contact with surface. The phase difference wheels are made of elastic materials for application of controlled pre-loads at contact surfaces during locomotion. The difference between height and width of each wheel as well as the elastic properties of the materials determine the pre-load pressure applied during locomotion. The pre-load pressure is not strongly dependent on the orientation of locomotion. This enables locomotion in vertical, inclined and even upside-down orientation and also in the non-gravity environment.

Self-loading locomotion mechanism and application thereof

The present invention describes a process for saccharification of lignocelluloses to sugars using whole microbial cells, which are enriched from cultures inoculated with paper mill waste water, wood processing waste and soil. A three-member bacterial consortium is selected as a potent microbial inocula and immobilized on inedible plant fibers for biomass saccharification. The present invention further relates the design of a dual bioreactor system, with various biocarriers for enzyme immobilization and repeated use. Sugars are continuously removed eliminating end-product inhibition and consumption by cell.
