Abstract

The invention provides a vacuum assisted resin infusion fabric compacting characteristic and permeability performance integrated testing device. The invention for the first time provides a fabric compacting characteristic and permeability performance integrated testing idea in vacuum assisted resin infusion, the device is capable of performing integrated experiment test of fabric compacting characteristic and permeability performance, and is capable of accurately researching the influence factors such as compacting strength, compacting time and cycle loading, fabric layers and fabric braiding methods on the compacting characteristic under a dry state and a moisture state of the fabric, and is capable of testing permeability of the fabric in plane and thickness direction. The device can realize the test for the fabric performance under same condition of the vacuum assisted resin infusion, employs a self-designed negative pressure controller, a pressure tester and an eddy current displacement sensor can realize automatic control of various influence factors, and can obviously increase the experiment efficiency of the fabric compacting characteristic and permeability performance test and can optimize the test cost.

Description

technical field [0001] The invention relates to an integrated testing device for the compaction characteristics and permeability performance of fiber fabrics in a vacuum-assisted forming process, in particular to a manufacturing method for vacuum-assisted forming process of resin-based composite materials by optical fiber grating testing and pressure control technology In the process, the compaction characteristics and permeability performance of the fiber preform were tested. Specifically, it relates to a device for integrated testing of the compaction characteristics of fiber fabrics under dry and wet conditions and the permeability properties in the plane and in the thickness direction. Background technique [0002] The vacuum-assisted forming process of carbon fiber reinforced resin matrix composites has been widely used in the fields of aerospace, automobile industry and shipbuilding due to its low cost and easy manufacture of large-scale components. The compaction cha...
