Isotropic fiber-reinforced thermoplastic resin sheet, and process for production and molded plate thereof
An isotropic fiber-reinforced thermoplastic resin sheet wherein a chopped strand prepreg comprising a thermoplastic resin and a reinforcing fiber is layered so that the fiber orientation is random, the prepreg having a fiber volume fraction (Vf) of 20% to 50%, a length in the fiber axis direction of 15 to 45 mm, and a thickness of no greater than 0.13 mm, and the layered material is molded into sheet form by heating and pressing, and a molded plate obtained from the isotropic fiber-reinforced thermoplastic resin sheet. Even if the volume fraction of the reinforcing fiber is relatively low, a fiber-reinforced thermoplastic resin sheet and a molded plate that are excellent in terms of mechanical properties and their uniformity can be obtained.

The present invention relates to a sound absorbing and insulating material with improved heat resistance and moldability and a method for manufacturing the same, more particularly to a sound absorbing and insulating material having, as a surface layer, a heat-resistant material prepared by impregnating a binder into a nonwoven fabric formed of a heat-resistant fiber stacked on one side of a base layer formed of a conventional sound absorbing and insulating material, and a method for manufacturing the same.
The sound absorbing and insulating material of the present invention is a conventional sound absorbing and insulating material has improved sound-absorbing property, flame retardancy, heat-insulating property and heat resistance as compared to the conventional sound absorbing and insulating material, is applicable to parts maintained at high temperatures of 200 C. or higher due to the surface layer and is moldable into a desired shape during the curing of the binder impregnated into the surface layer. Therefore, the sound absorbing and insulating material of the present invention can be widely used in industrial fields requiring sound absorbing and insulating materials, including electric appliances such as an air conditioner, a refrigerator, a washing machine, a lawn mower and the like, transportation such as an automobile, a ship, an airplane and the like, construction materials such as a wall material, a flooring material and the like, and so forth.
THERMOCOMPRESSION DEVICE FOR PRODUCING RECYCLABLE HONEYCOMB PLATES AND METHOD IMPLEMENTED USING SAME
The invention relates to a thermocompression device for producing recyclable honeycomb plates with high mechanical strength, which, by means of the proposed configuration, enables high-speed production with an optimised operating width. For this purpose, the device comprises an area for continuously heating and pressing the supplied sheet, a cooling area, a calendering area and a moulding area. Advantageously, the moulding area comprises forming rollers provided with protuberances arranged in continuous rows distributed on the surface of the forming rollers, such that the rows are arranged cross-wise with respect to the sheet supply direction. Recyclable honeycomb plates are thus obtained. The invention also relates to a method implemented using the described thermocompression device.
Method for manufacturing a sandwich panel with improved impact and damping behaviors
A method for manufacturing an aeronautical panel with improved impact and damping behaviors. The method is applicable not only to flat panels but also to curved or highly curved panels, whatever their size and the shape of their core. The manufactured sandwich panels comprise dry fiber mats made from fabric material and/or non-crimp fabric material. In a particular embodiment, the fabric material and/or the non-crimp fabric material comprise dry fibers which are recycled and/or reused fibers.
VEHICLE HEADLINER AND APPARATUS OF MANUFACTURING THE SAME
The present invention relates to a vehicle headliner and an apparatus for manufacturing the same, in which a substrate is pre-molded into a shape of the headliner, and then rigid or semi-rigid polyurethane is partially continuously foam-molded on the entire surface of a molded substrate to match the shape and thickness of the headliner, thereby it is possible to simplify the manufacturing process while reducing unintended buzz, squeak and rattle (BSR) and weight. In this case, a mold used for foam-molding the polyurethane is divided into several split molds and then the split molds are connected in the form of a single chain, and the polyurethane is partially foam-molded as the split molds rotate so that the rigid polyurethane is partially and continuously foam-molded on the surface of the substrate.
Composite products and related methods for manufacturing composite products from recycled composite materials
A method of manufacturing a composite product includes recovering a wet composite waste from at least one of the manufacturing process or an end-of-life product. The wet composite waste includes a first resin and a plurality of first fibers that are bound together with the first resin. The method also includes grinding the wet composite waste after recovering the wet composite waste. The method also includes mixing the wet composite waste with the second resin into a homogeneous mixture and placing the homogeneous mixture into a cavity. The method includes curing the second resin of the homogeneous mixture such that the homogenous mixture hardens to form a composite product that includes the first resin, the second resin, and the plurality of first fibers.
Rapid fabrication and/or repair of fiber reinforced covalent adaptable network composites
A method for rapidly fabricating or repairing a fiber reinforced composite may include the use of a covalent adaptable network polymer (CAN) powder for encapsulating reinforcing fibers or welding to a CAN matrix. The fiber reinforced composite may be formed or repaired by applying CAN powder to reinforcing fibers or to a damaged area of a fiber reinforcing composite and compressing the CAN powder with the reinforcing fibers or the damaged area of the fiber reinforced composite at a relatively low temperature, temperature and processing time to form a CAN matrix. The method may be configured for fabricating a fiber reinforced composite having specific desired material properties by varying the arrangement and materials used.
