Abstract

The invention relates to an injection molding method and injection molding equipment for a single polymer composite product, and belongs to the technical field of molding processing of polymer composite materials. The injection molding method comprises the following steps of: plastifying and melting a matrix, preparing a prefabricated piece from a reinforcing material, fixing the prefabricated piece in a die cavity, closing a die, injecting the molten matrix into the die cavity to soak the prefabricated piece, maintaining the pressure and cooling, and thus obtaining the single polymer composite product, wherein the matrix and the reinforcing material are the same polymer. The method has the advantages of high product strength, material recycle, complex product shape, short molding period, batch production, high production efficiency and the like. The injection molding equipment consists of an injection molding machine and the die. By adopting the conventional injection molding machine, the die has the advantage that only one fixed mechanism and one reasonably designed pouring system are required to be added on the molding component compared with the conventional design; and the equipment is simple in structure and easy to operate, and can be used for preparing the single polymer composite product by injection molding.

Description

technical field [0001] The invention relates to an injection molding method and equipment for single-polymer composite material products, and belongs to the technical field of polymer composite material molding processing. Background technique [0002] With the rapid development of modern science and technology, especially cutting-edge technology fields such as aerospace, people have put forward more and more technical requirements for materials, such as improving strength, reducing quality, integrating structure and function, and reducing costs. Traditional metals, Single materials such as polymers or ceramics are far from meeting these requirements. Therefore, the compounding of materials came into being. Composite materials are materials composed of two or more different materials through a composite process. It not only maintains the characteristics of the original component materials, but also obtains new properties that the original components do not have through the ...
