20180104863 · 2018-04-19 ·

A tooling system for fabricating a composite structure comprising a printed thermoplastic material tooling component having a non-tooling surface and a tooling surface, wherein the tooling surface defines a predetermined shape for the composite structure. The tooling system may further comprise a printed thermoplastic material tooling base structure having a plurality of non-tooling surfaces to support the printed thermoplastic material tooling component during layup or cure. The printed thermoplastic material tooling base structure may employ a support structure, such as a honeycomb support structure or a filler material.

Mold for manufacturing a component

A mold for manufacturing a component is provided. A mold has a mold surface representing a negative image of the component. The mold has openings in the mold surface. Flow channels extending from the openings in the mold surface and are connectable to a suction device. Further, the mold has a periphery delimiting the mold surface. A bag is fixed to the periphery of the mold. The bag is inflated to a pressure level above ambient pressure. The pressure is released from the bag while sucking the bag to the mold surface using the suction device. Fabrics are layered onto the bag while the bag is kept sucked to the mold surface. Resin is introduced into the fabrics and then the resin is cured.

Method for producing molded body

The present invention provides a method for producing a molded body, having the step 1 of applying a composition containing an alicyclic urethane (meth)acrylate to a thermoplastic resin substrate to obtain a coated material, the step 2 of irradiating the obtained coated material with an active energy ray to cure the composition, obtaining a laminated material having a cured product layer obtained from the cured composition, and the step 3 of subjecting the obtained laminated material to bending processing to obtain a molded body, wherein the alicyclic urethane (meth)acrylate has a structure having an alicyclic structure represented by the formula (A), and a group having two or more (meth)acryloyl groups represented by the formula (B), and further has a polymerizable double bond equivalent of 100 to 1,000 g/mol.

Methods and systems for using actuated surface-attached posts for assessing biofluid rheology

Methods, systems, and computer readable media for using actuated surface-attached posts for assessing biofluid rheology are disclosed. According to one aspect, a method for testing properties of a biofluid specimen includes placing the specimen onto a micropost array having a plurality of microposts extending outwards from a substrate, wherein each micropost includes a proximal end attached to the substrate and a distal end opposite the proximal end, and generating an actuation force in proximity to the micropost array to actuate the microposts, thereby compelling at least some of the microposts to exhibit motion. The method further includes measuring the motion of at least one of the microposts in response to the actuation force and determining a property of the specimen based on the measured motion of the at least one micropost.

Monofilament-reinforced hollow fiber membrane

A hollow fiber membrane is formed by embedding a braid having a spiral open weave of monofilaments only, to avoid a whiskering problem common in prior art multifilament braid-supported tubular membranes. 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 it can be infiltrated with membrane polymer which, when coagulated embeds the braid positioning it around the lumen. The spiral weave, free of any circumferentially constricting monofilament, when embedded in film, allows the membrane to be biaxially distensible. In other words, 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.
