Manufacturing of polymer matrix composites using vacuum assisted resin infusion molding

Purpose: The purpose of the paper is to manufacture the polymer matrix composites using vacuum assisted resin infusion molding. Design/methodology/approach: Electrical heating resistances are used for heating of table. The temperature control is achieved by means of acquiring temperatures using thermocouples located beneath the table surface. VARIM table is divided into eight regions. Each region has an independent closed loop temperature control system. Findings: By using a PLC and a touch screen, the system is capable of adjusting the desired temperatures, up to 200°C, and corresponding time intervals for curing cycles. The main advantage of using a PLC as a control unit for this system is to have a flexible control for changing the cure conditions. Research limitations/implications: The setup is capable of controlling the level of vacuum and the temperature of the heating table, single sided tool. By using the VARIM system, high quality and void-free composite plates are fabricated. Originality/value: The paper is supposed to give significant tips to researchers who intend to setup and utilize VARIM technology in their works.
