Disclosed are processes for In-Mold coating of a substrate. The processes include: introducing a curable composition to a mixhead at a first elevated pressure, the curable composition comprising a first polymeric component and a second polymeric component, the introducing of the curable composition to the mixhead comprising mixing the first and second polymeric components by impingement to form an intermediate composition; introducing the intermediate composition to a secondary mixer, the introducing of the intermediate composition to the secondary mixer comprising mixing the intermediate composition to form a coating composition; and introducing the coating composition into a mold containing a substrate to form a curable coating on a surface of the substrate.

A method of manufacturing a fiber-reinforced composite material which is molded by impregnating a fiber-reinforced sheet with a resin and curing the resin includes: placing the fiber-reinforced sheet in a cavity of a mold; and molding the fiber-reinforced composite material, the molding including injecting the resin into the cavity of the mold, impregnating the fiber-reinforced sheet with the resin, and curing the resin. In the molding, after fine air bubbles contained in the resin are placed at a predetermined position of the cavity, the resin is cured.

A system is disclosed for additively manufacturing a composite structure. The system may include a head having a matrix reservoir, a nozzle fluidly connected to the matrix reservoir and configured to discharge a composite material into a feature of an existing component. a guide configured to detect a location of the feature, and a cure enhancer configured to expose composite material discharging from the nozzle to a cure energy. The system may also include a support configured to move the head in multiple dimensions, and a controller in communication with the cure enhancer and the support. The controller may be configured to cause the support to move the head during discharge of the composite material into the feature based on the detected location of the feature.

A prepared mold tool having a thermoplastic surface layer polymer coating on the mold surface of the mold tool or prepared prepreg having a thermoplastic surface layer polymer coating on the surface of the thermoplastic fiber reinforced prepreg are described that enhance first ply laydown of thermoplastic fiber reinforced composite prepregs onto mold tools for prepreg forming or in situ tape placement. Resulting thermoplastic fiber reinforced composite parts from a thermoplastic fiber reinforced thermoplastic composite material having structural reinforcement fibers with one or more high performance polymers, and a thermoplastic surface layer polymer coating which forms a polymer blend with the high performance polymers of the thermoplastic fiber reinforced composite material thereby imparting improved properties, and methods for making and using same, are provided herein.

A glove stripping apparatus (15) for fully stripping a partially stripped elastomeric dip-moulded glove (2) from a hand-shaped dip-moulding former (4) comprises a gripping device (25) relatively movable with respect to a downwardly hanging cuff end portion (10), a gripping actuator (32), a stripping actuator (35) and a controller for controlling the operation of the actuators. The relative movement of the gripping device and the downwardly hanging cuff end portion is driven by the stripping actuator. The gripping device has first and second gripping members (24, 26) movable relative to each other by the gripping actuator. The gripping members provide opposed gripping surfaces (34, 36) for gripping the cuff end portion. The first gripping member and the second gripping member initially provide a horizontally extending gap between the gripping surfaces which receives the cuff end portion. The gripping members are moved to reduce the gap (40′) until the cuff end portion is restrained between the gripping surfaces with a beaded cuff end (3) of the glove being below the gap. The gripping members are moved downwardly (46) together towards the beaded cuff end so that the cuff end portion moves upwards relative to the gap until the beaded cuff end (3) is caught by the gap (40′). The downward movement is then continued until the glove is fully stripped from the dip-moulding former.

A system and method for forming 3D printed structures includes printing an outer shell portion and filling an interior of the outer shell portion to form an inner portion. The outer shell portion and inner portion may have differing material properties. The outer shell portion may be anchored to the base component.

Disclosed is a method of producing a pattern for a decorative panel. The method includes applying a clear gel coat on a mold to form a clear layer. The clear layer is cured and then digitally printed with one or more inks so as to produce a pattern on the clear layer. Also disclosed is a decorative panel including a clear layer, an opaque layer and a pattern digitally printed on the clear layer, between the clear and opaque layers, such that the pattern is visible through the clear layer.

Methods for manufacturing a turbomachine composite part, such as a fan blade, are provided. The composite part has a fibrous structure with a three-dimensional fibrous preform coated with a surface fibrous web, and which is embedded in a polymer matrix The methods include: forming the surface web in a cavity of a mold in order to shape it, wetting and forming the preform on the surface web in order to shape it, and closing the mold, drying the fibrous structure, and injecting thermosetting resin into the mold in order to form said polymer matrix. The surface web is wetted before and/or during the forming thereof.

Systems for manufacturing bulked continuous carpet filament from polymer, where the systems are configured for: (1) passing polymer flakes through a crystalliers; (2) melting the polymer to create a first single stream of polymer melt; (3) separating the first single stream of polymer melt into multiple streams of polymer melt; (4) exposing the multiple streams of polymer melt to a pressure of between about 0 millibars and about 25 millibars in a chamber; (5) recombining the multiple streams of polymer melt into a second single stream of polymer melt; and (6) providing the second single stream of polymer melt to one or more spinning machines that are configured to form the second single stream of polymer melt into bulked continuous carpet filament.

The purpose of the present invention is to provide a coating material composition that is suitable for in-mold coating applications, and is capable of forming a coating film particularly having excellent adhesion properties to materials. This thermosetting coating material composition is for a plastic material and contains a urethane (meth)acrylate (A) having 2-4 polymerizable unsaturated groups and an aliphatic structure, a polymerizable unsaturated compound (B) having one polymerizable unsaturated group per molecule, and a polymerization initiator (C), and is characterized in that the polymerizable unsaturated compound (B) contains a polymerizable unsaturated compound (b1) that (i) has a boiling point equal to or higher than the curing temperature thereof, (ii) has a rate of permeation with respect to a plastic material of at least 1 mass %, and (iii) has a coating liquid turbidity of at most 50 degrees when mixed with the urethane (meth)acrylate (A).
