A new consolidation method for the laser-assisted filament winding of thermoplastic prepregs is discussed: for the first time a diode laser is used, as well as long glass fiber reinforced polypropylene prepregs. A consolidation apparatus was built by means of a CNC motion table, a stepper motor and a simple tensioner. Preliminary tests were performed in a hoop winding configuration: only the wi...

In this paper, the buckling behavior of a composite lattice cylindrical shell is studied and effects of rib defects on the distribution of stress field and buckling response of the shell is investigated. A three dimensional finite element buckling analysis of the lattice shell is carried out using ANSYS suit of program. Geometrical data and material properties of the shell are obtained from the...

Filament winding is a process in which tensioned resin-impregnated continuous fibers are placed on a specified path on a mandrel. Automated systems have been adopted to deliver the fiber with a fixed level of accuracy. Process simulation is a very important question in automated applications. Moreover, the necessity to process complex shape objects leads to consider different alternatives to de...

Filament winding reinforcement is often applied to fulfill high-pressure resistance and lightweight for gas cylinder productions. This article analyzes the pattern corresponding characteristics filament cylinders based on resulting thickness strength such that can be made as light possible. In order prevent sliding between material surface during process, a range of angles do not exceed maximum...

This paper mainly presents the simulation and design of adaptive control scheme for filament winding automatic control system. According to the model reference adaptive control principle, an algorithm of fuzzy immune PID is adopted, which is suitable for the velocity and position servo system control. The simulation results show the controller design is practical, and not only has achieved fine...

This paper presents an integrated real-time control system for a Robotic Filament Winding manufacturing cell. The architecture is based on a multiprocessor system employing four processor boards. The system incorporates a hierarchical control layout with the task specification at the highest level and the robot and winder set point tracking at the lowest. Eventual design goals include a PC fron...

Simultaneous process of filament winding and curing a reinforced polymer is widely used in composite industries. This process is normally used for manufacturing cylindrical structures of the composite materials, which have been used in many fields including aerospace and chemical industries, sports and military. The process consists in winding fibres passing through a resin bath on a mandrel at...
