摘要： A method for laser-cutting a carbon fiber substrate such as a preform is configured from fabric material comprising at least carbon fibers, characterized by cutting the carbon fiber substrate at initial conditions which have been set so that the state of the substrate that is being cut with a laser can be suppressed with or prevented from deviating from a target state. By the method, it is possible to effectively solve various problems such as dissipation of heat, positional shifting from the focal length range of the laser, and soot, and the carbon fiber substrate can be stably cut at the target desired state.

摘要： An RTM molding method includes disposing a reinforcing fiber substrate in a cavity of a mold consisting of a plurality of dies, clamping the mold, and thereafter injecting resin to complete molding, characterized in that divided areas with respect to the surface direction of the reinforcing fiber substrate are assumed, each divided area is one in which injected resin expands over the entire surface in the area and can be substantially uniformly impregnated in the thickness direction of the substrate, and resin introducing paths are formed for respective assumed divided areas for introducing the injected resin into the respective divided areas; and an RTM molding device. When a relatively large molded product is to be molded, a molding step from resin injection to impregnating/curing can be implemented at high speed without generating a non-resin-flowing area, thereby enabling a high-quality molded product to be produced free from voids, etc., with a molding time shortened and production speed and volume increased.
摘要翻译： RTM成型方法包括将增强纤维基材设置在由多个模具构成的模具的空腔中，夹持模具，然后将树脂注入到完全成型中，其特征在于，相对于增强纤维的表面方向分割区域基板，每个分割区域是其中注入的树脂在该区域的整个表面上膨胀并且可以基本上均匀地浸渍在基板的厚度方向上的区域，并且为各个假定分割区域形成树脂引入路径，以引入注入树脂分成各个分区; 和RTM成型装置。当要成型相对较大的模制产品时，可以高速实现从树脂注入到浸渍/固化的成型步骤，而不产生非树脂流动区域，从而能够生产高质量的模制产品空隙等，成型时间缩短，生产速度和体积增加。
