Truss framework composite material product, and flowing medium forming mould and forming method thereof

Abstract

The invention discloses a truss framework composite material product, and a flowing medium forming mould and a forming method thereof. The truss framework composite material product consists of a framework reinforcing material, a skin material and a filling material, wherein the framework reinforcing material is formed by fixedly connecting rods and has the profile of the product; the skin material is attached to nodes of the framework reinforcing material, which serve as an outer profile; the filling material is embedded between the rods of the framework reinforcing material in the skin material; the flowing medium forming mould of the truss framework composite material product comprises a container, a cavity, a potting device and a flowing medium; and the forming method of the truss framework composite material product comprises the steps of potting the filling material into the cavity and curing the filling material to obtain the product. In the invention, the step of manufacturingthe mould cavity is saved, so that the manufacturing cost can be greatly reduced and the reinforcement function of the framework material can be fully exerted. The size of the product can be very large and is not limited to the conventional machining equipment, the length and the number of the rods of the reinforcing material are changed, and the skin material and the reinforcing material can very easily form the new cavity, so that the upgrading speed of the product is increased.

Description

technical field [0001] The invention relates to a composite material product with a reinforced skeleton and its molding die and molding method, which can be widely used in large-scale composite products such as boats, automobiles, trains, airplanes, rockets, fan blades of wind power generators, urban landscapes or functional buildings, etc. The field of molding and processing of material products, especially the molding and processing occasions where materials are poured into the cavity in fluid form and then chemically reacted or cooled and solidified to obtain products. Background technique [0002] Most of the yacht hulls, marine engineering buildings, high-speed locomotives and aircraft cabins are made of composite materials. In addition to the hand lay-up process that has been used for a long time, the molding and manufacturing technology of such large-scale composite products is increasingly using compression molding and molding methods. The hand lay-up process of com...

Problems solved by technology

[0003] The invention aims to solve the problems of high mold cost of large-scale composite material products, complex molding and processing, and inability to meet the needs of modern manufacturing product modeling individual design and the ever-changing development needs of upgrading. There are traditional mold manufacturing methods such as metal and other solid materials through machining such as engraving and cutting or EDM, and the reinforced skeleton material is designed into architectural structures such as trusses or Fuller structures to directly support the skin material to form the cavity of the mold, so that the reinforcement The material plays a full role in the entire structure, reducing material waste, thereby creating a molding manufacturing method for truss composite products that does not require reprocessing of mold cavities
