Thermoplastic composite materials for portable information handling system enclosures

Enclosure parts for portable information handling systems may be made by heat pressing material layers together. The material layers may include outer fiber-reinforced thermoplastic layers and a core thermoplastic layer comprising a plurality of thermoplastic film layers. The core thermoplastic layer may be die cut to create voids that reduce weight of the enclosure part. A finishing layer may be added, along with attachment features.

11590682 · 2023-02-28 · ·

The present invention relates to a molded product manufactured from a high heat resistant bio-based polycarbonate ester. More specifically, the molded product has excellent heat resistance, and thus can be applied to various fields such as those of automobiles, electrical electronics, displays, aviation, machines, lighting, medicine or food.

Thermoplastic carbon fiber laminate with a randomly oriented fiber core layer

In one or more embodiments, one or more systems, methods, and/or processes may place a first outer layer, a core layer, and a second outer layer in a mold; and may heat the mold to at least thirty degrees Celsius above a glass transition temperature (Tg) for a period of time. In one or more embodiments, the polycarbonate fibers may be between eight and ten deniers per filament. In one or more embodiments, the Tg may be no more than 105 degrees Celsius. In one or more embodiments, the one or more systems, methods, and/or processes may further allow the first outer layer, the core layer, and the second outer layer to cool below the Tg, after the period of time. For example, after the layers cool, a shear modulus of the core layer may be in a range of 0.9868 megapounds per square inch (msi) to 2.2730 msi.

Polymeric material comprising modified lignin

A polymeric material comprising a first polymer and a second polymer where the first polymer is a natural or a synthetic polymer and the second polymer is modified lignin. The modified lignin is modified with an alkyl containing group via linker wherein the linker is an ether group and wherein the alkyl containing group is derived from fatty acid methyl ester.

Monofilament-reinforced hollow fiber membrane with scalloped lumen

A hollow fiber membrane is formed by embedding a braid having a spiral open weave of monofilaments only, to avoid a whiskering problem. The open weave is characterized by contiguous, circumferential, rhomboid-shaped areas of polymer film separated by monofilaments. When the braid is supported on a plasticized PVA cable having a scalloped periphery, the braid can be infiltrated with membrane polymer which, when coagulated, embeds the braid positioning it around the lumen. The embedded spiral weave, free of any circumferentially constricting monofilament, allows the membrane to be biaxially distensible. The membrane has give not only in the axial or longitudinal direction but also in the radial direction. Give in the radial direction permits soiled membranes to be backwashed under higher pressure than in a comparable braid which is not radially distensible.
