摘要:
Novel absorbable polymer blends are disclosed. The blends are useful for manufacturing medical devices having engineered degradation and breaking strength retention in vivo. The blends consist of a first absorbable polymeric component and a second absorbable polymeric component. The weight average molecular weight of the first polymeric component is higher than the weight average molecular weight of the second polymeric component. At least at least one of said components is at least partially end-capped by a carboxylic acid group. Further aspects are medical devices made therefrom.
摘要:
Multi-functional and high-performing fabric comprising a first layer of yarns woven to form the fabric wherein the yarns comprise at least one unitary graphene-based continuous graphitic fiber comprising at least 90% by weight of graphene planes that are chemically bonded with one another having an inter-planar spacing d002 from 0.3354 nm to 0.4 nm as determined by X-ray diffraction and an oxygen content less than 5% by weight. A majority of the graphene planes in such a continuous graphitic fiber are parallel to one another and parallel to a fiber axis direction. The graphitic fiber contains no core-shell structure, has no helically arranged graphene domains or domain boundaries, and has a porosity level less than 5% by volume, more typically less than 2%, and most typically less than 1% (practically pore-free).

摘要:
The present disclosure is directed to a woven fabric comprising filament yarns. The filament yarns may be comprised of a polyetherimide polymer. The woven fabric may provide flame resistance as well as static/anti-static control. The woven fabric can be employed to provide garments, such as protective garments for a cleanroom.
摘要:
A separating film with an anti-adhesion layer for preventing an adhesive connection between a thermally curable levelling compound, applied in the region of a joining zone of a first component, and a joining zone of a second component to be joined to the first component. The anti-adhesion layer is provided, at least in parts, with a heating layer. As a result of the actively electrically heatable heating layer of the separating film, which is an integral part of the separating film, the processing time for joining two components, which are subject to tolerances, using a thermally curable levelling compound (known as liquid shimming), can be reduced by at least 40% compared with the conventional process.
摘要:
A stabilizable preform precursor for composites is provided. The preform precursor has at least one layer of a structural fabric comprised of reinforcing fibers where at least one of the layer(s) of structural fabric has integrated therein one or more stabilizing fiber(s) that dissolves at a dissolution temperature in a resin for infusing into the structural fabric to make the composite. The stabilizing fiber stabilizes the stabilizable preform precursor when the stabilizable preform precursor is subjected to an elevated temperature.

摘要:
A flame protective fabric structure (1) comprises a fabric (10) being formed with multiple yarns (20), each yarn (20) made of a fiber blend of at least a first fiber component and a second fiber component. The first fiber component comprises flame resistant viscose fibers (22) in an amount of at least 50% of the fiber blend weight and the second fiber component comprises meltable fibers (24) in an amount of at least 10% of the fiber blend weight. The fabric (10) is formed as a woven fabric with a total fractional cover factor of greater than 60% having a capability to withstand a horizontal flame exposure of 10 seconds without hole formation according to ISO 15025/14116_Index III.
