Coated composite component
A coated composite component includes, in this order, a composite component, a fluorine-containing film and/or a fluorine-containing woven fabric, knitted fabric or crocheted fabric, and a tear-off fabric. A method for producing a coated composite component including, in this order, a composite component, a fluorine-containing film and/or a fluorine-containing woven fabric, knitted fabric or crocheted fabric, and a tear-off fabric.
Light engines for photo-curing of liquid polymers to form three-dimensional objects
Three-dimensional objects are formed by photo-curing a liquid polymer by exposure to a radiation, which radiation (e.g., at 410 nm) is provided by a collimated light source composed of an array of light emitting diode (LED) sources, an array of baffles, and an array of lenses. The baffles limit beam widths of each individual LED source in the array of LED sources, and the array of lenses is located one focal length from said array of LED sources.
RELEASE MATERIAL
Provided is a method of manufacturing a circuit board including preparing a board structural body (11) and covering a conductor circuit element (13) on an outermost layer of the board structural body (11) with a cover film (14), wherein a heat treatment is performed while having a release material (15) interposed between the cover film (14) and a heat-processing device. The release material (15) is a laminate at least including, sequentially from the cover film toward the heat-processing device, a low friction film (16) selected from an ultrahigh-molecular-weight polyethylene film and a polytetrafluoroethylene film, a first aluminum foil (17), a first high-density polyethylene film (18a), a second high-density polyethylene film (18b), and a second aluminum foil (19). The first high-density polyethylene film (18a) and the second high-density polyethylene film (18b) are positioned such that respective MD directions are perpendicular to each other.
SYSTEMS AND METHODS FOR MANUFACTURING PREPREG TAPES
Systems and methods for manufacturing unidirectional fiber prepreg tapes for CMC articles are provided. In one exemplary aspect, the method includes casting a matrix material on a carrier film to form a matrix film. The matrix material of the matrix film is then allowed to dry for a predetermined time. The matrix film is then wrapped on a drum and the matrix material is wet to a predetermined viscosity with a solvent. Thereafter, a fiber tow that includes of a plurality of fibers is wound about the drum so that the fiber tow penetrates into the matrix material and the matrix material impregnates the fiber tow to form the prepreg tape.
Method for pre-preg manufacturing
A method of making a composite part comprises covering a mold tool for a composite part with a parting film, the parting film comprising a polymer sheet and a pressure sensitive adhesive. The parting film is positioned so that the polymer sheet is between the mold tool and the pressure sensitive adhesive. At least one layer of pre-preg is layed up on the parting film covering the mold tool to form a layed-up composite part. The pre-preg comprises an adhesive. The layed-up composite part is removed from the parting film.
USE OF POLYMETHYLPENTENE FILM AS RELEASE FILM IN A METHOD FOR SHAPING COMPOSITE MATERIAL
The present invention relates to the use of a single layer polymethylpentene film as release film in a method for shaping a composite material.
THREE-DIMENSIONAL FABRICATING SYSTEMS FOR RAPIDLY PRODUCING OBJECTS
This invention relates to rapid prototyping systems, specifically, a composition for a release film comprising one or more base materials selected from the group consisting of silicone, polycarbonate, polyethylene, and polypropylene; and one or more free-radical inhibitors.
SYSTEM AND PROCESS FOR VACUUM MOLDING
A system is for making a molded article made of foamed material, including a die (1) composed of an upper section (11) and a lower section (12), separable and coupled to define a recess. A first suction (20) creates a vacuum to allow shaping a plastic film on the wall of a portion of the recess of the sections (11) and (12). A tensioner and lock (30) of the plastic film allow positioning and fastening the plastic film outside the recess.
Multi-Stage Debulk and Compaction of Thick Composite Repair Laminates
A method for fabricating a repair laminate for a composite part having an exposed surface includes applying a release film to the exposed surface and forming an uncured ply stack assembly on the release film. The uncured ply stack assembly is formed by forming and compacting a series of uncured ply stacks. The release film and ply stack assembly is then removed from the exposed surface. A bonding material is then applied to the exposed surface, and the uncured ply stack assembly is applied to the bonding material. The ply stack assembly and bonding material are then cured.
Assembly with temporary protective film
The invention relates to a composite comprising (i) a plastics component or (ii) a semifinished plastics product with a protective layer system, where the protective layer system comprises a plastics film and an organosilicon plasma polymer layer, the organosilicon plasma polymer layer is arranged between the (i) plastics component or the (ii) semifinished plastics product and the plastics film and, after the hardening of the (i) plastics component or of the (ii) semifinished plastics product, the organosilicon plasma polymer layer adheres more securely to the plastics film than to the (i) plastics component or the (ii) semifinished plastics product.
