Introduction

Continuous fiber composite material is a composite material composed of continuous fibers and a resin matrix. It has the advantages of high strength, lightweight, corrosion resistance, etc., and is widely used in aerospace, automobile manufacturing, shipbuilding engineering, sports Equipment and other fields.

However, traditional preparation methods often face many challenges. First of all, traditional preparation methods usually require multiple tedious steps such as fabric cutting, stacking, and preforming, resulting in long preparation cycles and low production efficiency. Secondly, traditional preparation methods require a lot of labor and equipment investment and are costly, which restricts the large-scale application of continuous fiber composites. In addition, traditional preparation methods are often limited by the preparation process and cannot meet the diverse needs of composite structures, resulting in product design restrictions and affecting product performance and market competitiveness.

Therefore, in order to solve the challenges of traditional preparation methods and improve the preparation efficiency and product quality of continuous fiber composite materials, an efficient preparation technology is urgently needed, that is, the application of rapid prototyping technology has become particularly important. Rapid prototyping technology, with its high efficiency, flexibility and accuracy, can realize the rapid preparation of continuous fiber composite materials and meet the needs of the composite materials market. It has important significance and application prospects. Next, this article will explore the application and development of rapid prototyping technology in the preparation of continuous fiber composite materials.

Traditional preparation method of continuous fiber composite materials

Preparation:

The preparation process of continuous fiber composites usually involves multiple steps such as fabric cutting, stacking, and preforming. The complexity and tediousness of these steps lead to problems such as long preparation cycles and low production efficiency.

• First, in the preparation process of traditional continuous fiber composite materials, the fiber fabric needs to be cut according to the design requirements to obtain the required shape and size. This step requires professional cutting equipment and skilled operating techniques, and often requires a lot of time and human resources.

• Next, the cut fiber fabrics need to be stacked, that is, multiple layers of fibers are stacked together to form the structure of the composite material. This process requires a high degree of precision and attention to ensure that the orientation and position of the fibers in each layer match the design requirements, while also taking into account the arrangement of the fibers and the uniformity of the resin impregnation.

• Finally, after the stacking is completed, a pre-forming process is required, that is, the stacked fibers are added to the mold, and then pressure and temperature are applied to solidify the resin. This process also requires strict control of conditions and timing to ensure the quality and performance of the final product.

Limitations and Disadvantages:

• The traditional preforming process often requires a lot of time and human resources, has a long preparation cycle, and has low production efficiency. This not only increases production costs, but also limits the large-scale application of composite materials.

• The traditional preforming process is limited by the preparation process and cannot meet the diverse needs of composite material structures. For example, traditional preforming processes are often difficult to prepare products with complex shapes and rich details, resulting in product design restrictions and affecting product performance and market competitiveness.

• The traditional preforming process also has quality problems such as uneven resin infiltration and easy generation of bubbles and defects, which affects the quality and reliability of the final product.

Therefore, in order to solve the various limitations and shortcomings of traditional preforming processes and improve the preparation efficiency and product quality of continuous fiber composite materials, an efficient, accurate and flexible preparation technology is urgently needed, that is, the application of rapid prototyping technology has become particularly important. . Next, this article will deeply explore the application and development of rapid prototyping technology in the preparation of continuous fiber composite materials.
