Abstract:
The panel member molded from a fiber reinforced plastic material includes the waved plate section. In the waved plate section, lateral wall portions are connected to upright wall portions through bent portions. Each lateral wall portion includes a general portion extending along the wavelength direction of the waved plate section. A plate thickness of the general portions of the lateral wall portions is set thinner than a plate thickness of the upright wall portions. The general portion at least does not include bubbles with a larger diameter than reinforcing fibers. An array direction of the reinforcing fibers disposed in the general portion of the lateral wall portion is set in a direction running along the wavelength direction of the waved plate section.

Abstract:
This invention relates to a use of a non-woven thermoplastic resin in combination with a curable moulding material comprising a fibrous reinforcement material and a thermoset resin material by bringing the thermoplastic resin in contact with the curable moulding material during or following assembly of the moulding material. The thermoplastic resin has a melting point below the gel temperature of the thermoset resin material to reduce the void fraction and increase the ILSS of a cured moulding manufactured from said moulding material forming a laminate structure in comparison to a cured moulding manufactured from said moulding material in which the fabric is absent forming the laminate structure.
Abstract:
Provided herein is an apparatus of manufacturing a molding material for use in a method of manufacturing a molding material that can prevent a crack from occurring in the molding material. A cylindrical die (3) is slid downward along an upper hollow compression mold (4) and a lower hollow compression mold (2) with a molding material (35) held between the upper hollow compression mold (4) and the lower hollow compression mold (2). After that, the upper hollow compression mold (4) is moved upward to relatively move the upper hollow compression mold (4) and the lower hollow compression mold (2) away from each other. After a slurry diffusion member (7) is removed, the molding material (35) is taken out.
Abstract:
Methods of making a fiber-reinforced composite article are described. The methods may include providing fibers to an article template, where the fibers have been treated with a coupling-initiator compound. They may further include providing a pre-polymerized mixture that includes a monomer and a catalyst to the article template. The combination of the fibers and the pre-polymerized mixture may be heated to a polymerization temperature where the monomers polymerize around the fibers and form at least a portion of the composite article. The article may then be removed from the article template. Examples of the fiber-reinforced composite articles may include wind turbine blades for electric power generation.
Abstract:
At the time of molding, in the stator, the resin material flows inside the vent channels that are formed on the terminal block. At this time, as the resin reservoirs which are formed by expanding cross-sections of the vent channels are provided on the mounting surface of the terminal block, the resin material can be retained in the resin reservoirs. This consequently prevents the resin material from flowing through the vent channels to the outside of the terminal block. When the resin leaked part, which is the resin material that has leaked from the vent channels to the outside and been hardened, falls while using the motor, there is an adverse effect on another piece of equipment. Thus, the resin reservoirs that are formed in the vent channels act effectively in terms of preventing the resin material from flowing to the outside.
