Jet molding device and method for resin based composite antenna housing

Abstract

The invention discloses a jet molding device for a resin based composite antenna housing. The jet molding device comprises a male mold, a reinforced fiber fabric, a rotating turntable, a jet device, atwo-dimensional moving device and a resin generation device, wherein the male mold is sleeved with the reinforced fiber fabric; the rotating turntable is arranged below the male mold and used for driving the male mold and the reinforced fiber fabric to rotate around respective vertical axes; the jet device is used for atomizing resin and jetting the resin into the reinforced fiber fabric; the two-dimensional moving device is connected with the jet device and used for driving the jet device to conduct two-dimensional movement along the offset curve of the outline of the male mold; and the resin generation device is connected with the jet device and used for heating the resin and conveying the resin to the jet device. The resin is jet to the reinforced fiber fabric through high-pressure airflow, the resin more easily permeates into the fabric, and the material uniformity is better. The jet molding process can be directly monitored through naked eyes and other means, defects existing inthe molding process can be treated in real time, and thus the molding quality and the percent of pass are improved.

Description

technical field [0001] The invention relates to the technical field of resin-based composite material radome preparation, in particular to a resin-based composite material radome forming device and method. Background technique [0002] The radome is an important part to protect the internal antenna from the external environment. In addition to meeting the requirements of strength, heat resistance, and rain erosion resistance, the radome is also a key window for the antenna to receive and transmit signals, and must have good wave transmission performance. With the advancement of my country's aerospace, meteorological and military technology and the development of the military situation, the research and manufacture of high-precision radars such as long-range precision tracking and measurement radars and high-gain antennas has become an urgent task. The development of high-performance radome needs It is also becoming more and more urgent. [0003] Resin-based wave-transparent ...

Problems solved by technology

Injection molding technology is also used in resin-based composite materials, but the traditional method is to mix short fibers with resin and spray them into the mold through a nozzle, such as the document "FRP Injection Molding Technology" (The Sixteenth National FRP / Composite Material Academic of FRP Society Proceedings of the Annual Conference, 2006, 153-155) introduced the injection molding method of FRP products, the composite material made by this method has large inhomogeneity, and cannot be applied to the field of radomes with high performance requirements
