Light Resin Transfer Molding (L-RTM) for Close Mold Process   Introduction to L-RTM process   The traditional RTM process, because it is a closed-mold process, has the advantages of reducing volatile organic compounds (VOC) emissions (up to SPPm or less), expanding the range of available raw materials, reducing labor, being environmentally friendly, and producing products

What is the RTM Composite Closed Molding Process?   The so-called closed mold molding process is a process method for molding composite components when the female and male molds are closed. SMC, BMC molding, injection molding, RTM, VEC and other technologies are all closed mold molding processes. Due to the formulation of environmental laws and

  Introduction to HP-RTM and Wet Compression Molding of Composite Materials   This article mainly introduces two composite material molding processes, namely HP-RTM and wet compression molding process.   HP-RTM is the abbreviation of High Pressure Resin Transfer Molding in English. The full name is High Pressure Resin Transfer Molding, referred to as HP-RTM molding

  T-RTM Thermoplastic Resin Transfer Molding   Thermoplastics, with all their advantages, are difficult to use as matrices for high-performance composites, as their high viscosity complicates the impregnation process. Overcoming the high viscosity can be reactive thermoplastics, such as PA-6, which is synthesized from ε-caprolactam (ε-CL) monomers by anionic ring opening polymerization (AROP). The synthesis

Thinking and Practice of Composite Rapid Prototyping Technology (I): Problems of HP-RTM   Composite materials, especially carbon fiber composite materials, have low molding efficiency and high production and processing costs, which have always been the core issues restricting their large-scale use. Taking carbon fiber as an example, in 2021, the domestic carbon fiber production

Understanding The RTM Process   RTM (Resin Transfer Molding) Process is a resin transfer molding process, a new type of compression molding method. It is a low-cost manufacturing technology for advanced composite materials in aerospace. It has the advantages of low cost, short cycle, low labor cost, less environmental pollution, precise manufacturing dimensions, smooth

  Creating Perfect Products, Sharing Experience of Zero Mistakes in RTM (liquid) Molding Process!   The 29th training - RTM (liquid) molding process training has ended. During the few days of service, I listened to the theoretical courses of teacher Zhang Yanfei almost throughout the whole process, and also followed the industry colleagues in the

  RTM Process to Reduce Costs   Airbus Bremen aims to replace dozens of prepreg parts and assembly operations with a single-piece, multi-spar composite flap.     Reducing manufacturing costs through RTM: The Composite Multi-Flap (CMF) project at Airbus Bremen simplifies the production of 7.4-meter-long outboard flaps for narrow-body aircraft by integrating 26 individual carbon

  RTM Molding Process and Classification Introduction   RTM Molding Process and Classification RTM refers to a process technology in which low-viscosity resin flows in a closed mold, infiltrates reinforcing materials and solidifies into shape. It belongs to the category of liquid forming or structural liquid forming technology of composite materials. The specific method is
