A thermoset polyurethane resin matrix has an elongation similar to that of the reinforcing fibers so the load on the entire reinforcement is evenly distributed. It can be desirable to select the dimensions and cross-sectional profile of overlying filament subunits to prevent or minimize the potential for an overlying filament to slip past into or past an underlying filament subunit or section of a filament subunit during compression molding. Pultrusion is generally defined as a continuous process of manufacturing of composite materials with constant cross-section whereby reinforced fibers are pulled through a resin, possibly followed by a separate pre-forming system, and into a heated die, where the resin undergoes polymerization and where the reinforced plastic is shaped and the resin is cured. The shaped filament subunits can also be designed to minimize the number of piece parts and thereby facilitate assembly efficiency.

"You can achieve structural parts that are repeatable and affordable, with any fiber type. A continuous and aligned fiber-reinforced composite is to be produced by many. The idea of taking continuous carbon tows and breaking them into short "staple" fibers and then aligning and recombining them into yarns first appeared in the mid-to-late 1980s in products from Courtaulds' Heltra Division, ICI Fiberite (Tempe, Ariz. ), and DuPont (Wilmington, Del. A section of a part may be formed from one or more filament subunits or portions of one or more filament subunits.
The process according to claim 1, wherein the fibers are partially cured at the curing station, and further comprising the step of directing the partially cured composite strength member into an embossing roll for implanting a surface texture onto at least one side of said composite. Some difficulties with the current art have been identified. The fiber-reinforced composite part of any one of aspects 1 to 11, wherein, each of the compositions independently comprises a matrix material; and the matrix material of each of the two or more aligned fiber portions is continuous with the matrix material of each of the other two or more aligned fiber portions. No surface preparation of the FRP composite is necessary to ensure proper bonding of the adhesive because a thermoset polyurethane resin matrix is being utilized as the matrix of the FRP. A fiber-reinforced part can have a tensile strength from 100 MPa to 600 MPa, from 100 MPa to 400 MPa, from 150 MPa to 350 MPa, or from 200 MPa to 300 MPa.
If fibers are all bunched in one area, they may require more force to move through the die, and this force could cause fiber failure. A fiber filament includes a straight section of filament and a shaped filament subunit. The dimensions of the heating block can be selected based on the dimensions of the filament and the glass transition temperature of the thermoplastic. The tensile strength of the panels resulted in values of 146. Composite strength member 140 is then directed into a post cure chamber 136. The advantage of doing so, the method for attachment, and conventional methods for making the structural members are also established in the art.
