内部具有空腔，纤维增强塑料结构，它特别适用于例如增强的车辆用车轮（10）的塑料的纤维的成形方法。 首先，以适应主要由多个刚性的颗粒（图6a）至所述袋的颗粒（6），以形成多个芯的（至4H 4A）。 增强纤维基材如预浸料或织物分发，从而相邻的多个芯部之间夹。 例如，为了使通过在芯（通过4H 4a）的成型原料包裹所述预浸料坯（3）中，通过组合多个所述多个原料模制模具内的布置，所述模具 压缩成型YoHara材料。 在压缩成型中，所述通过施加局部每个芯的加压（通过4H 4a）中，通过变形以增加芯的内压，在芯和预浸料坯，或预浸料坯之间的外表面的一部分 消除，该模具的成型表面之间存在的间隙中。

Inside with a cavity, fiber reinforced plastic structure, it is particularly applicable to for example method of molding a fiber reinforced plastic of the vehicle wheel (10). First, to accommodate particles consisting mainly of a plurality of rigid particles (6a) to the bag (6) to form a plurality of core (4a to 4h). The reinforcing fiber substrate, such as a prepreg or fabric to distribution so as to be interposed between a plurality of adjacent core. For example, create a wrapped by molding raw material in the core (4a to 4h) said prepreg (3), arranged by combining a plurality of the plurality of molding raw material inside the mold, said forming compression molding YoHara material. During compression molding, said part of the outer surface pressed locally pressurizing of each core (4a to 4h), by deforming to increase the internal pressure of the core, between the core and the prepreg, or the prepreg eliminating the gap that exists between the molding surface of the mold.
