Abstract

Pre-preg material is widely used to produce a composite material in the composite industry. The aim of this project is to conceptually design a lab-scale pre-pregger machine for in house production of pre-preg material. The main idea is to decrease the size of the existing machine and reduce the cost to fabricate it. The proposed conceptual design of the machine is limited to a pre-pregging process for a unidirectional pre-preg tape. This project is divided into two junctures: conceptual design and control strategies. The conceptual design of the pre-pregger machine is drawn using AutoCAD software and SolidWork 2014 is used for simulation purpose. At this stage, the design focuses on four major components: drum, resin bath, guider and fiber spindle. The pre-pregger machine is designed with a flexible drum which can be installed and removed easily from the drum holder. The drum is designed with two sizes :300 mm and 600 mm in diameter. The different size in diameter will make the machine become more flexible. In another juncture, Programmable Logic Controller (PLC) was chosen to control the pre-pregger machine. The CX-ONE OMRON PLC was used to design the ladder diagram of the controller. In order to simulate and test the correctness of the controller, a simple electrical setup has been made. The setup consists of three motors, sensors and push button. The simulated setup proved that the proposed conceptual design of the pre-pregger machine is workable. In a nutshell, the aim of the project has been successfully achieved. It is hoped that the development of the lab-scale pre-pregger machine can be made in the near future.
