摘要： A method of making a composite part includes the steps of placing a first section of a fibrous pre-form in a mold and infusing the first section of the fibrous pre-form with a resin so as to produce a resin-infused portion and a non-resin-infused portion. Next, the method includes coupling the non-resin-infused portion to a second section of the fibrous pre-form to create a coupled non-resin-infused portion. Then, the coupled non-resin-infused portion is infused with resin to create a second resin-infused portion and a second non-resin-infused portion. These steps are repeated to separately infuse different sections of the part until the part is complete. The corresponding apparatus preferably employs a rigid mold having a shape defining only a portion of the composite part to be made. And, the method is particularly adapted to making both cored and non-cored structures that are large or unconventionally shaped.
摘要翻译：制造复合部件的方法包括以下步骤：将纤维预成型件的第一部分放置在模具中，并用树脂注入纤维预成型件的第一部分，以便产生树脂注入部分和非 - - 注入部分。接下来，该方法包括将非树脂注入部分连接到纤维预成型件的第二部分以产生耦合的非树脂注入部分。然后，将耦合的非树脂注入部分注入树脂以产生第二树脂注入部分和第二非树脂注入部分。重复这些步骤以分开注入零件的不同部分，直到零件完成。相应的装置优选地采用刚性模具，该刚性模具具有仅形成要制造的复合部件的一部分的形状。而且，该方法特别适用于使大型或非常规成形的核心和非核心结构两者。
