RTM Combination Fabrics
Resin transfer moulding (RTM) is a versatile and widely used technique to manufacture composite components. RTM Core Mat(Biaxial fiberglass fabric)consists of two or more layers of fiberglass rovings which are stitch-bonded.one layer of rovings consists of parallel aligned roving and different layers of rovings can be oriented differently and have different linear density.
It is mainly used in the RTM process, to manufacture the nacelle, automobile, train parts etc.

The Advantages of RTM process

(1) The required operating space is small, the raw material utilization rate is high, and the basic investment and production cost are low.

(2) Various forms of reinforcing materials, such as non-oriented materials, textile fibers and woven fabrics, can be used, and the fiber content can be as high as 50% to 60% (mass fraction). Suitable for composite molding of thick three-dimensional fabrics as reinforcements.

(3) The degree of freedom in product design is large. From this point of analysis, the RTM process is not only superior to the autoclave forming process, but also superior to the filament winding forming process and the pultrusion forming process.

(4) The curing process is simple and there is no requirement for pressure holding and deflation.

(5) Molds and products can be computer-aided design, greatly reducing the update cycle. The mold can be made from a variety of materials and is easy to manufacture.

(6) The molding process is carried out under closed conditions to reduce the harmful effects of harmful components on the human body and the environme
