عملية RTM ألياف الكربون

Detailed explanation of carbon fiber RTM process

عملية صب ألياف الكربون RTM (صب نقل الراتنج) هي عبارة عن تقنية تصنيع مواد مركبة ذات قوالب مغلقة، والتي تقوم بحقن الراتنج في قوالب ألياف الكربون المشكلة مسبقًا وتستخدم القالب للضغط لإتمام المعالجة والقولبة. تُستخدم هذه العملية على نطاق واسع في صناعة الطيران وصناعة السيارات وغيرها من المجالات نظرًا لدقتها العالية وجودة سطحها الممتازة.

1、 Overview of Carbon Fiber RTM Process

The RTM process involves pre setting dry carbon fiber fabrics or preforms in a closed mold, and then injecting liquid resin into the mold through vacuum or mechanical pressure to solidify and form high-performance composite components. This method combines the advantages of manual pre molding and automated resin injection, making it particularly suitable for producing components with complex geometric shapes.

خصائص العملية

High surface quality: The surface of the component is smooth and can be directly used for appearance parts..

Complex structure adaptation: Suitable for manufacturing components with reinforcing ribs or curved surfaces..

Low volatility: Closed mold environment reduces harmful gas emissions.

Precision Control: Mold design ensures precise dimensions..

2、 Carbon fiber RTM process flow

تتضمن العملية بشكل أساسي الخطوات التالية:

1. Preparation of prefabricated parts

According to the design requirements, dry carbon fiber fabric or cloth is cut and manually or mechanically laid in a mold to produce a preform.

2. Mold sealing and vacuuming

Close the upper and lower molds, ensure airtightness with sealing strips, and extract air through a vacuum pump to reduce bubbles and assist resin flow.

3. Resin injection

Inject liquid resin into the mold through the resin feed port using vacuum or pressure to infiltrate the preform. The resin flow rate and pressure need to be precisely controlled.

4. Curing and demolding

After injection, heat the mold (usually 100 ° C to 160 ° C) to cure the resin. After solidification, open the mold, take out the molded parts and perform post-processing.
