METHOD FOR HYBRID PREFORMS
A hybrid preform comprises a bundle of unidirectionally aligned fibers, and at least one partial cut that extends part of the way, but not all of the way, through a transverse cross section of the bundle of fibers at least one location along the length of the bundle.
Material preparation device and related methods
Material preparation devices and related methods include a material or substrate assembly and an application assembly for applying a fiber material.
Forming composite features using steered discontinuous fiber pre-preg
Interlaminar features of a composite structure are laid up by placing and steering individual chopped fiber pre-preg segments onto a substrate.
Tube Sealer
A device for sealing sample tubes comprises a tool assembly configured to interface with a rack holding a plurality of sample storage tubes, the tool assembly holding a plurality of punches and a die plate including a plurality of cutting holes, with each of the plurality of cutting holes accepting one of the plurality of punches. The tool assembly receives a foil sheet between the punches and the die plate. The device includes an actuator enabling linear movement of the tool assembly. Linear movement of the tool assembly towards the rack engages the die plate against the rack and punches the punches through the cutting holes of the die plate to punch a plurality of sealing sections from the foil sheet and to press and seal each of the sealing sections against a top end of each of the plurality of sample storage tubes in the rack.
Textile-like in-mold sheet, production method of the same, preform molded body, textile-like resin molded body, and production method of the same
Disclosed is a textile-like in-mold sheet that is to be integrated with a resin molded body molded by injection of a molten resin by in-molding. The textile-like in-mold sheet includes at least a fiber sheet layer, a first adhesive layer, and a textile material layer, in this order from a surface that will serve as a side to be integrated with the resin molded body. Alternatively, the textile-like in-mold sheet includes at least a textile material layer and a temporary surface protection layer temporarily bonded to the textile material layer, in this order from the surface to be integrated with the resin molded body.
INCISED PREPREG, CROSS-PLY LAMINATE, AND PRODUCTION METHOD FOR INCISED PREPREG
An intermediate base material is provided that is excellent in the conformity to three-dimensional shapes and that, when formed into a fiber reinforced plastic, develops good surface quality and high mechanical properties.
According to one aspect, an incised prepreg is provided that has, in at least a partial region in a prepreg that contains unidirectionally oriented reinforcing fibers and a resin, a plurality of incisions that divide reinforcing fibers, wherein, in the case where a population is made up of the numbers of incisions contained in ten small circular regions of 10 mm in diameter randomly selected in the aforementioned region, a mean value for the population is 10 or greater and a coefficient of variation therefor is within 20%.
Thermoplastic composite components for commercial aircraft seats
Described are thermoplastic composite parts (30, 110) made up of resin-based fiber composites for use in aircraft furnishings. The thermoplastic composite parts (30, 110) can be formed into various shapes including bends so as to be suitable for replacing heavier sheet-metal components (100), particularly in aircraft furnishings.
Apparatus and method for stretching and repitching elastic members
The current invention concerns a method and apparatus for stretching and repitching an elastic member for attachment to a moving substrate, the elastic member being stretchable in at least a longitudinal direction and said elastic member in an essential non-stretched condition comprising an initial length along said longitudinal direction, the method comprising the steps of: (1) providing the elastic member in essentially non-stretched condition to a set of repitching members with an initial supply pitch, said set of repitching members comprising at least a first repitching member and a second repitching member, and optionally one or more repitching members arranged between said first and said second repitching member; (2) receiving said elastic members arranged in non-stretched condition between said set of repitching members, whereby the distance between the first and the second repitching member corresponds to the initial length of the elastic member; (3) moving at least said first and said second repitching members following trajectories diverging from each other, thereby stretching said elastic members arranged between the repitching members to an application length which is longer than the initial length and which corresponds to the length of said elastic member in elastically stretched condition, whereby said repitching members are moved with selectively variable velocity when transferring said elastic members to selectively vary the application pitch of said elastic member in stretched condition on said substrate, the variation of the speed of said repitching members determining the application pitch of said elastic member in stretched condition on said substrate, characterized in that during step (3), said set of elastic members are rotated around a common rotation axis while the elastic member is being stretched from the initial length to the application length. Additionally, the invention concerns a method and apparatus for stretching and repitching an elastic member for attachment to a moving substrate whereby the elastic members are held by repitching members, which are rotated at an essentially constant rotational speed around rotation axes in trajectories, said trajectories being defined by having a different radial distance from the rotation axis to the repitching member rotating around said rotation axis at the application position where the elastic member is attached to the substrate, than at the initial position where the elastic member is received by the repitching members, thereby changing the pitch of the elastic members.
Container manufacturing apparatus
A container manufacturing device for performing manufacture of a pre-form and a container in a single station via one stop is provided. The container manufacturing device includes a pre-form molding module configured to form a shape of a pre-form of a container using a resin material, an injection module connected to the pre-form molding module and configured to supply the resin material to the pre-form molding module, a container molding module configured to inject air to the pre-form to expand the pre-form and to form the shape of the container and including a container mold, and a rotary table with a rib plate suspended thereon while rotating between the pre-form molding module and the container molding module, the pre-form or the container being mounted on the rib plate.
Sleeve applicator system and method
The present invention is related to a sleeve applicator system for applying a heat-shrinkable sleeve to an object that moves in a first direction. The present invention further relates to a corresponding method. According to the invention, a second mandrel is mounted in a flexible manner to a first mandrel. A second drive system is used for moving the heat-shrinkable sleeve from the first mandrel over the second mandrel towards the object. The second drive system is further configured to push the second mandrel such that the second mandrel moves along with the moving object during the application of the sleeve.
