Abstract: A method produces thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle obtained by impregnating reinforcing fibers made from continuous fibers with a thermoplastic resin, said method including: an application step in which a sheet-shaped reinforcing fiber bundle obtained by arranging reinforcing fibers made from continuous fibers in one direction is passed through an application section which retains thermoplastic resin, and the thermoplastic resin is applied to the sheet-shaped reinforcing fiber bundle to constitute a thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle; a further impregnation step in which the applied thermoplastic resin is further impregnated into the inside of the thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle; and a shaping step in which the thermoplastic resin-impregnated sheet-shaped reinforcing fiber bundle is shaped and solidified by cooling.

Abstract: A method for producing a three-dimensional preform from an intermediate preform blank (30, 70), which contain undulations (31) in a portion thereof. The preform blank (30, 79) may be formed on a tool surface (60) containing undulations (61) using an automated placement method such as Automated Tape Laying (ATL) or Automated Fiber Placement (AFP), in which narrow-width strips of material are dispensed side-by-side. Various preform blanks (30, 70) and molding tools (10, 50, 80) have been designed to produce shaped preforms having generally C-shape and Z-shape cross-sections.

Abstract: A process is provided for thermal molding an article with at least one layer of thermoplastic fibers that are non-woven and uni-directionally oriented in combination with at least one layer of reinforcing fibers. The reinforcing fibers including glass, carbon, nature based, and combinations thereof; alone or mixed with chopped thermoplastic fibers. Upon subjecting the layers to sufficient heat to thermally bond in the presence of non-oriented filler fibers, thermoplastic fiber fusion encapsulates the filler fibers. The filler fibers impart physical properties to the resulting article and the residual unidirectional orientation of the thermoplastic melt imparts physical properties in the fiber direction to the article. By combining layers with varying orientations of uni-directional fibers relative to one another, the physical properties of the resulting article may be controlled and extended relative to conventional thermoplastic moldings. The uni-directional fibers may have discontinuities along the length of individual fibers.

Abstract: A composite charge used to compression form a stringer comprises multiple plies of unidirectional, prepreg having various fiber orientations. Certain of the plies have a pattern of angled cuts allowing the plies to stretch both longitudinally and transversely during forming, thereby reducing ply wrinkling in contoured areas of the stringer.

Abstract: The invention aims to provide a tape-shaped prepreg including unidirectionally oriented reinforcing fibers and a thermoplastic resin composition and being high in handleability during molding and high in adhesiveness to other members. The tape-shaped prepreg includes unidirectionally oriented reinforcing fibers and a thermoplastic resin composition and has an arithmetic average roughness (Ra) of 0.1 to 10 μm in a direction perpendicular to the orientation direction of the reinforcing fibers, as measured according to JIS B 0601: 2013, and a warpage rate of 5% or less as determined by the procedure specified in (i) to (iii) below: (i) place a test piece of the above tape-shaped prepreg having a length of 100 mm in the fiber orientation direction on a plane in such manner that the end portions curl upward, (ii) measure the vertical distance from the highest position at the right end of the curled tape to the plane, which is denoted by a, and the vertical distance from the highest position at the left end to the plane, which is denoted by b, and calculate the arithmetic average of a and b, which is defined as the warpage distance, and (iii) calculate the warpage rate by the following equation: warpage rate (%)=warpage distance (mm)/100 (mm)×100.

Abstract: A method for creating a fan cowl with a hollow hat stiffener includes pressing a resin film between a non-crimp fabric (NCF) and a release poly-film to create a resin-fabric sheet. The method further includes cutting the resin-fabric sheet to a pre-determined shape to create at least one of a first resin-fabric preform, a second resin-fabric preform, and a third resin-fabric preform, draping at least the first resin-fabric preform over a tool to create an outer layer of the fan cowl, setting a mandrel over the outer layer, and draping the second resin-fabric preform over at least a portion of the mandrel and at least a portion of the first resin-fabric preform to form the hollow hat stiffener having a geometry similar to a shape of the mandrel.

Abstract: A fiber composite body, in particular a structure stiffening element, has a number of struts which are formed by reinforcing fibers which are embedded in a polymer matrix and which in a region of the respective strut run substantially parallel to one another. The struts are arranged in a truss-like profiled structure which is produced by winding or intertwining the reinforcing fibers.

Abstract: Non-standard, resin-infused fiber bundle includes localized regions of fibers having a sub-nominal amount of polymer resin positioned along its length. These regions function as “bending regions,” where the non-standard resin-infused fiber bundle can be readily deformed by virtue of the reduced amount of resin. The bending regions segregate the non-standard resin-infused fiber bundle into what is, effectively, discrete (smaller) segments of (standard) resin-infused fiber bundle. The ability to easily manipulate the non-standard, resin-infused fiber bundle via the bending regions is useful for creating fiber-bundle-based preforms, and preform charges (assemblages of fiber-bundle-based preforms).
