Embodiment Construction

[0024] The present invention is described in detail below in conjunction with accompanying drawing:

[0025] A kind of preparation method that is used for composite material Z-pin strengthened stiffened plate forming equalizing plate, the technology of this preparation method is as follows:

[0026] 1) According to the size and shape of the longitudinal ribs and skin of the Z-pin reinforced wall plate, order a set of metal master molds; then order another set of master molds according to the size of the transverse ribs; use the above two sets of master molds The mold was cleaned with acetone;

[0027] 2) Configure the glue solution according to the ratio requirements to prepare the prepreg;

[0028] 3) Pave and paste longitudinal ribs and skin conjoined equalizer plates and transverse rib equalizer plates on the corresponding molds, and calculate the number of paving layers according to the thickness of the reinforced wall plates;

[0029] 4) After curing at room temperature...

Abstract

The invention relates to a preparation method for a pressure equalizing plate used for forming of a composite Z-pin reinforced stiffened plate, and belongs to the field of manufacturing of composites. The method is simple in low-pressure epoxy glass steel plate manufacturing process, low in cost, easy in machining, suitable for stiffened plates in different sizes, accurate in positioning and capable of well controlling the web thickness and surface quality of the stiffened plate, solving the problems of Z-pin pinpoint embedding and deformation of the pressure equalizing plate and guaranteeing the product quality, has high market application value, and is worth applying and popularizing in the industry.

Description

technical field [0001] The invention relates to a method for preparing a composite material Z-pin reinforced plate to form an equalizing plate, which belongs to the field of composite material manufacturing. Background technique [0002] In recent years, high-performance and low-cost composite material technology has been gradually applied in aviation and aerospace composite material structures, and Z-pin technology is one of the advanced manufacturing technologies, which is to preform the pre-prepared Z-direction fiber The body is embedded in a prepreg or uncured composite material in a certain way, and a three-dimensionally reinforced composite material structure is formed after curing. The structure can improve the bonding ability between the sub-layers of the laminated board, thereby solving the problems of poor toughness, easy delamination, and poor impact capacity between the laminated boards of composite materials, and can also play a role in improving the strength of...
