Abstract

The invention designs a mold for pipy composite materials suitable for resin transfer molding (RTM), which can enable the prepared pipy composite materials to achieve the required standard and the requirements. The invention relates to the mold for the pipy composite materials and belongs to the technical field of design and preparation of the molds of the resin transfer molding (RTM) of the pipy composite materials. The structure of the mold disclosed by the invention is characterized in that a male mold and a female mold are closed for forming a pipy mold cavity, and the outer ring of the mold is provided with a sealing strip for sealing and a fixing screw, so that the overall sealing property of the mold can be well ensured. In addition, the mold adopts the design of a unique annular groove at a resin injection port, on the basis of ensuring the injection stability during the preparation of the pipy composite materials, resin can better and uniformly infiltrate pipy fabric, the production of bubbles can be prevented, and the resin can finally flow out of a resin outlet. Simultaneously, a unique cylindrical male mold inner core of the mold disclosed by the invention can enable the demolding operation to be simple and easy to operate, and the operation is easy.

Description

Technical field [0001] The invention relates to a mold of tubular composite material, which belongs to the technical field of mold structure design of tubular composite material resin transfer molding (RTM). The mold is suitable for the RTM molding process of tubular composite materials. The mold design can well ensure the uniformity of the thermosetting resin infiltration of the tubular reinforcing fabric, and the unique slot design ensures the stability of the injection and ensures the preparation of tubular composite materials. On the basis of the stability of injection, the resin can infiltrate the fabric evenly and stably without air bubbles, and finally the resin flows out from the outlet. The unique cylindrical male mold inner core of the invention makes the demoulding operation simple and easy to operate. [0002] The invention relates to a mold, in particular to a mold suitable for producing tubular composite materials by RTM forming technology. Background techniqu...
