Filament winding technique is a relative cost-effective manufacturing process compared to other composite fabrication processes, which has more potential market prospect. Filament winding technique fabrication capability mainly depends on filament winding machine configuration and software development. Based on market research survey, available filament winding machines have the desktop structure, complex control system and heavy weight characteristics, which show technique obstacles in current stage. Several small-size filament winding machines aimed to research development and education purposes such as X-Winder LCC and Pultrex suppliers, which limited technique application. In order to break through machine structure and software limitation, it is necessary to design a portable small-size filament winding machine using open-source control software. Therefore, the objective of study is to design and fabricate a prototype of laboratory scale 3-axis filament winding machine, and evaluate and verify the machine design performance through validation tools. In order to evaluate filament winding machine performance capability, winding circular and speed tests are performed. Filament wound carbon/epoxy cylinders are evaluated according to winding angle precision test, burn-out test and quasi-static axial compression test. The laboratory scale 3-axis filament winding machine has been successfully designed and fabricated, which consists of a rotation unit, a carriage unit and a ring pay-out eye unit. The open-source control system is divided into hardware and software sections. I-Winder software is also designed using Bluetooth connection, which adopts wireless connection technology. Meanwhile, filament wound carbon/epoxy cylinders with ±45°, ±60° and ±75° winding angles are successfully fabricated using the lab-scale filament winding machine. The resulted machine performance are discussed as follows; machine has 0.83-1.13 mm and winding circular repeatability, the carriage unit speed ranges from 0 to 2000 mm/min, and the rotation unit speed ranges from 0 to 150 rpm. Winding angle precision test of specimen obtains +1° winding angle deviation value. Fibre weight fraction of specimens ranges from 39.93 % to 46.77 %. In addition, the effect of winding angle on compressive properties is studied according to quasi-static axial compression test. With the winding angle increases the compressive strength generally exhibits the increasing trend from ±45° to ±60° winding angle, and decreasing trend from ±60° to ±75° winding angle. Furthermore, the compressive modulus linearly decreases with increasing the winding angle. With the winding angle increase, energy absorption and specific energy absorption generally exhibits the increasing trend. This lab-scale structure design is significant to produce filament wound composite tubes at different winding angles using dry and wet winding methods, which aims to composite fabrication industries and academic research purpose. The remote control system is also designed and highlighted, which provides advanced control system in filament winding machine development history.
