The content of the lecture is mainly divided into six parts:   Part 1, Overview of LCM

Let You Understand Composite Material LRTM Molding Process with Various Process Introductions   The main composite material forming processes include:   Hand lay-up process, RTM process, vacuum bag process, autoclave process, molding process, tube rolling process, pultrusion process, roll forming process, winding process, pressure bag process, etc.   Must-read technology for composite materials: RTM process

RTM Molding Process   RTM Molding Process The basic principle of the RTM process is shown in the figure below. First, the reinforcement material preform, core material and embedded parts are pre-placed in the mold cavity, and then the resin is injected into the closed mold cavity under pressure or vacuum force to wet the

 PP Needled Punched Mat   PP Needled Mat possess not only the advantage of regular needle-spun mat but also the filtering of much better acid & alkaline than polyester，so the polypropylene needled mat generally applied to the occasions that flue gas temperature below 100 ℃ and high acidity and high alkalinity, or the solid-liquid separation

Closed Mold RTM Process Mold Material Selection and Production   RTM (Resin Transfer Molding) is a process method that injects resin into a closed mold to infiltrate the reinforcing material and solidify it. It is suitable for the molding of multi-variety, medium-volume, high-quality advanced composite materials. This advanced process has many advantages. It can use

RTM Mold Graphic Production Tutorial   Dear composite material friends, have you ever thought about the detailed production process of RTM molds? If you are asked to be a technical leader and direct the workers to make RTM molds step by step, can you do it? After reading this article, you can almost do it

  RTM Closed Mold Forming Process and Mold Design and Production Process   The so-called Closed Mold Molding Process is a process method for molding composite material 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

  What is the difference between L-RTM and vacuum infusion VIP process? - Be Sure to Read the Last Paragraph   For many friends who know the two processes, they should know the difference between them. But many friends who have been doing hand lay-up process still have some doubts about the difference between the

Application of Closed Mold Technology in the Shipbuilding Industry   Content Summary The traditional manufacturing process of composite shipbuilding mainly adopts hand lay-up and injection molding, both of which belong to open mold process The closed mold process shipbuilding discussed in this exchange is: Vacuum induction Wet vacuum bag pressing RTM LRTM Why use closed
