Method for producing a composite molded body and corresponding composite molded body

An apparatus and method for producing a composite molded body in which several layers of prepregs are laid over one another, adhesively bonded to each other and cured under pressure and/or vacuum, wherein the prepreg layers laid over one another are introduced into an airtight shell, the interior of the shell is connected to a vacuum source and evacuated and the molded body is cured together with the shell in a furnace. In order to develop a corresponding method and a composite molded body which can be produced with it, which does not have at least some of the above disadvantages, an antifriction agent is introduced into the interior of the shell before the evacuation of the shell.

Article of footwear formed from two preforms and method and mold for manufacturing same

A method of manufacturing a midsole includes placing first and second preforms into a midsole recess of a mold, with first and second portions of the mold defining a first overflow chamber connected to the first recess; closing the mold by positioning the first and second portions in contact with one another; heating the mold for a predetermined period of time at a predetermined temperature such that the first and second preforms melt and bond together to form a midsole, with a portion of each of the first and second preforms flowing into the first overflow chamber to form a first overflow portion; removing the midsole from the mold; allowing the midsole to expand; and cutting away the first overflow portion.

Methods and systems from recycling carpet and carpets manufactured from recycled material

The present invention pertains to carpet and methods of making and recycling carpet. In one aspect, the carpet includes: a primary backing which has a face and a back surface; a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing; an adhesive composition backing; and an optional secondary backing adjacent to the adhesive backing. The method of making carpet includes extrusion coating the adhesive composition onto the back surface of a primary backing to form the adhesive composition backing. The method of recycling carpet can recover one or more polymeric carpet components.

Process for recycling detergent pouches

A process for recycling a multi-compartment water-soluble pouch including a phosphate-free bleach-containing cleaning composition and an enveloping material. The pouch includes at least two compartments. A first compartment includes a solid composition and a second compartment includes a liquid composition. The process includes the steps of: a) releasing the compositions from their respective compartments by preferably cutting open the enveloping material; b) mixing the compositions; c) adding a moisture sink to the mixture; and d) optionally drying the mixture.

METHOD OF MAKING RADIOCHROMIC DOSIMETER USING CALCEIN DYE

Calcein-PVA film and Calcein solution dosimeters is made for high dose applications. Systematic evaluation of dosimetric properties for the films is being conducted and was found useful for routine dosimeter in industrial radiation processing. The color bleaching of CA-PVA film and CA solution increases gradually with increasing absorbed dose in the dose range of 5-30 kGy for film, and 0.25-1 kGy for solution. The dose sensitivity increases significantly with increase of concentration of CA dye. The response of the CA-PVA films was slightly affected by relative humidity and temperature. The stability of film dosimeters and solutions after irradiation was very high and were stable for up to 30 days.

Laser beam welding method and molded components fabricated thereby

The invention relates to a method for laser welding two plastic components A, B brought into contact at least in the joining area, wherein component B facing away from the laser radiation consists of a plastic matrix with a white pigmentation of 1.5 5-20 wt.-%, and component A facing the laser radiation, through which the laser beam passes in the welding process, exhibits a plastic matrix. For a given laser wavelength the travel distance of the laser beam through the component A measures at most 10 mm, and given a white pigmentation of the component A in wt.-%, the product of the travel distance of the laser 10 beam through the component A in mm and white pigmentation in wt.-% is less than 1.25, and the travel distance of the laser beam through the component A measures at most 1 mm.
