RTM resin transfer mat is a special material used in the composite material RTM (Resin Transfer Molding) molding process. It is usually made of high-strength fiberglass or carbon fiber fabric and a special resin flow layer(PP mat)

It is a material used in the composite material RTM (Resin Transfer Molding) molding process. RTM molding is a common composite manufacturing process that creates products with high strength and lightweight by mixing pre-prepared fiber reinforcements with resins and injecting them into molds for curing.

The flow mat is a special fiber-reinforced material, which has excellent permeability and high strength and is an indispensable part in the manufacture of composite materials.  

The followings are some main product features and analyses of RTM resin flow mat:

Excellent permeability: The mat has excellent permeability, which can quickly and evenly penetrate into the fiber fabric, so as to effectively fill the void and manufacture high-quality composite products

High strength and rigidity: Since the RTM resin flow mat is usually made of high-strength glass fiber or carbon fiber fabric, it has excellent strength and rigidity, which can provide stable support and protection for composite products.

Good chemical resistance: The mat usually has good chemical resistance, which can resist the erosion and corrosion of many chemicals, thus prolonging the service life and reliability of the product.

Easy processing and installation: The softness and plasticity of the mat make it easy to process and install. It can be cut, compressed and formed into products of various shapes and sizes and can be combined with other composite or metallic materials.

Lightweight: The mat is made of fiber-reinforced material, which is light in weight and can improve the lightweight effect of composite products.

Wide adaptability: Suitable for different fields, such as aerospace, automobile, shipbuilding, construction, etc., and provides high-performance composite material products for these fields.

Material preparation: It is usually composed of fiber reinforcement and resin coating. The fiber-reinforced material can be glass fiber, carbon fiber, etc. Resin coating can choose epoxy resin, phenolic resin, polyester resin, epoxy acrylate, and other materials.

Manufacturing process: It is often used in conjunction with the composite RTM molding process. The specific process is as follows:

In general, RTM resin flow felt is a high-performance, multi-functional composite material product that can be applied in various fields, such as automotive, aerospace, marine and construction, etc. It can provide products with excellent strength, stiffness and durability, and can improve manufacturing efficiency and cost-effectiveness.

Application：
