Abstract

The invention discloses a method for preparing a three-dimensional thermoplastic composite material based on an improved wrapped yarn structure. A wrapping device adopted by the improved wrapped yarn is characterized in that a gathering device is added on the original wrapping device. The preparation method comprises the following steps of preparation of wrapped yarn, weaving of three-dimensional orthogonal linen woven fabric fabrication and forming of composite materials. The invention provides a process for preparing three-dimensional orthogonal woven fabric enhanced-thermoplastic composite materials based on the improved wrapped yarn structure, and the distribution problem of thermoplastic resin on the fabrication can be effectively improved. The method has the advantages of simple process, low cost, high efficiency, energy saving, environmental protection and wide application.

Description

technical field [0001] The invention belongs to the technical field of preparation of green textile composite materials, and relates to an improved wrapping device, which adopts wrapping yarns and uses a three-dimensional orthogonal woven fabric as a reinforcement structure to produce a thermoplastic composite material with evenly dispersed resin. Background technique [0002] Green composite material is a new type of ecological material. It uses natural plant fibers to reinforce thermoplastic resins with different structures, and is a composite material made by high-temperature extrusion or hot-pressing molding processes. This type of composite material has low density, is easy to process, and can be recycled or degraded. The R&D and marketization of this material reduces the dependence on petroleum resources and alleviates the greenhouse effect caused by the large release of carbon dioxide, thereby implementing the concept of sustainable development. [0003] Today, short...
