Embodiment Construction

[0046] This embodiment is a device for measuring the sliding force between layers of carbon fiber prepreg, including a bracket 1, a load frame 2, a carbon fiber prepreg fixing seat and a carbon fiber prepreg sliding mechanism. Wherein, the bracket 1 is the carrier of this embodiment, and the bearing frame 2 is installed on the bracket panel 9 of the bracket. The carbon fiber prepreg fixing seat is located in the bearing frame 2, and the carbon fiber prepreg fixing seat includes two bases 6 with the same structure, one of which is an upper base and the other is a lower base. The upper base is fixed on the lower surface of the top plate 16 of the bearing frame, the lower base is fixed on the upper surface of the bracket panel 9, and the carbon fiber prepreg fixing surfaces of the two bases 6 correspond to each other and have a spacing, which is equal to the backing plate The sum of the thickness of the carbon fiber prepreg and the thickness of the four layers of carbon fiber pre...

Abstract

The invention discloses a carbon fiber prepreg interlayer slip force measurement device and method. A bearing rack is arranged on a bracket panel of a bracket; two bases for fixing carbon fiber prepreg are positioned in the bearing rack; a base plate of a carbon fiber prepreg slip mechanism is positioned between the two bases and is fixedly connected with a pulley steel wire rope in the carbon fiber prepreg slip mechanism; a pulley is fixed on a connecting plate; the connecting plate is fixed on a machine tool table-board, and the carbon fiber prepreg slip mechanism is driven to move through a machine tool, so that a relative motion is generated between the slipping carbon fiber prepreg and the fixed carbon fiber prepreg. The slip force of the slipping carbon fiber prepreg coated on the base plate is measured through a force sensor of an electronic universal testing machine. The force application is uniform, the heating temperature is easily controlled, the obtained measured data is reliable, and the measurement device is simple in operation, convenient, practical and high in applicability and can be popularized to a slip force measurement experiment of other types of prepreg.

Description

technical field [0001] The invention relates to the technical field of molding, in particular to a method and device capable of measuring interlayer slip force during the molding process of carbon fiber prepreg. Background technique [0002] In the process of making composite material preforms by thermal diaphragm forming process, in order to avoid the wrinkling and breaking of fibers, these fiber layers must be relatively slipped, and the slip between layers is beneficial to the forming process. The edge quality of the preform is mainly related to the interlayer slip effect of the composite material stack. The effect of the stress, strain and displacement of each layer of the composite material is almost consistent and the good edge forming quality proves that the interlayer slip effect is obvious. The change of curvature produces uniform interlayer slippage between layers, which ensures the quality of the molding and avoids separation between layers, corner wrinkles and un...
