Abstract
The invention provides a composite-material flexible hinge and a manufacturing method thereof. The composite-material flexible hinge comprises composite-material joints and a composite-material tubular flexible unit, wherein the two ends of the composite-material tubular flexible unit are assembled with the composite-material joints. The composite-material joints and the composite-material tubular flexible unit are made of a carbon fiber reinforced composite material; the composite-material joints are molded by adopting a compression molding process; and the composite-material tubular flexible unit is molded by adopting a reel pipe molding process. According to the composite-material flexible hinge provided by the invention, a light and high-strength carbon fiber reinforced composite material is adopted to manufacture the flexible hinge, so that weight reducing effect is obvious. The composite-material flexible hinge integrates power and a locking function, has a power providing function and an automatic locking function, does not need to additionally arrange devices such as a heating device or a locking device, is low in structure complexity, is high in expanding reliability, and is easily mounted and maintained.
Description
technical field [0001] The invention relates to aerospace engineering technology, in particular to a composite material flexible hinge and a manufacturing method thereof. Background technique [0002] Due to the limitations of the effective space and carrying capacity of the launch vehicle load compartment, large antennas and solar battery sails are sent into space in a folded and compressed form, and then unfolded into the required geometric configuration. Therefore, the deployable structure is an important part of the spacecraft, which is directly related to the operational performance of the spacecraft and the success or failure of the mission. In addition, considering the characteristics of reusability, convenient transportation and storage, and short construction period, the deployable structure has been widely used in the aerospace field. [0003] Hinges are an important part of deployable structures. Traditional mechanical typical hinges are generally composed of ma...
