摘要： A manufacturing method of composite material member includes a step of shaping a laminate including laminated prepreg sheets along a mold. The laminate includes a first layer in which fibers are oriented in single direction. In the first layer, a first surface crossing the single direction and a second surface crossing the single direction are confronted each other such that the first surface and the second surface face each other. Since the fibers are discontinuous between the first surface and the second surface, the laminate is easily shaped and wrinkles are hard to be generated in a composite material member to be manufactured from the laminate.
摘要翻译：复合材料构件的制造方法包括沿着模具成型包括层压预浸料片的层压体的步骤。层压体包括纤维沿单向定向的第一层。在第一层中，与单一方向交叉的第一表面和与单个方向交叉的第二表面相互面对，使得第一表面和第二表面彼此面对。由于纤维在第一表面和第二表面之间是不连续的，所以层压体容易成形，并且难以在由层压体制造的复合材料构件中产生皱纹。

摘要： The present invention relates to a method of molding a composite material structural member used mainly within structural members such as channel materials or angle materials, and also to a composite material structural member. An object of the invention is to provide a method of molding a composite material structural member that is capable of suppressing fiber creasing even for very long shapes having non-developable surfaces, and also to provide a composite material structural member.When pressing a prepreg laminate against a molding die, the method comprises a preparation step of preparing a prepreg laminate for molding by laminating a plurality of prepregs with different fiber orientations into a flat plate shape, and a pressure application step of pressing the prepreg laminate for molding prepared in the preparation step against the molding die, and in the preparation step, a specified prepreg having a fiber orientation that coincides with, or is close to, the direction of creasing occurrence is split, either within the region of creasing occurrence or in the vicinity thereof, along a direction that is effective in inhibiting creasing occurrence, and the split prepreg is then used in preparing the prepreg laminate.

摘要： Outer diameters of upper and lower flanges of a reel are formed equal to each other irrespective of a diameter of a hub, and a cylindrical wall having the same inner diameter as the hub of the reel having the small diameter hub is provided in the reel having the large diameter hub. Thereby, there is provided a low-capacity type recording tape cartridge, in which other parts can be used both as the reel having the small diameter hub and the reel having the large diameter hub only by changing the reels and a displaced angle of a recording tape does not vary with respect to a case sidewall of a leader member.

摘要： Textile structures for producing structural members such as reinforced spars of composite material and a method for producing the textile structures. In the textile structure at least two textile planar members, or plates, are integrally joined together by textile filaments such that the planes of the members intersect each other, at least one member being formed of layers of textile filaments which extend obliquely in at least two directions in a brace fashion with respect to the longitudinal and transverse directions of the member while the remaining members are each formed of layers of textile filaments extending along the longitudinal, transverse and vertical directions of the member.The textile structures are made by disposing filament guide members of required length in a vertical direction according to a desired configuration and design density of the structures and laying out textile filaments among said filament guide members so that they move longitudinally, transversely or orthogonally to form a plurality of textile planar members. The members are joined together by extracting the filament guide members and inserting filaments in the spaces vacated by the filament guide members.
