July 2014: New Developments in 3D Graphics and FEA/FEM interfaces

Shortly we will be releasing versions of Cadfil with the open for additional 3D graphics based on the OpenGL systems. With OpenGL compliant 3D graphics cards a wider range of animation and dynamic viewing become available. A brief preview can be seen in this link. We also recently did some testing if our FEA output into the ABAQUS systems, this has proved very successful and and overview can be seen in this link. With the FEA interfaces mandrel geometry and multi-layer fibre architecture (thickness/angle/material data) can be rapidly exported to commercial FEA software saving large amounts of time and leading to more rapid product development.

August 2013: New options to aid with the design of Filament Wound Poles and Masts

Poles and masts are an increasingly common application for filament Winding whether they be for lighting, communications , CCTV cameras or other applications of this type. Composite Poles have significant advantages over conventional materials and can have much better full-life cost when installation and maintenance costs are properly considered. For most masts and utility poles one of the key considerations is the bend stiffness under prescribed loads. Design standards such as BS EN40 or AASHTO-LTS5 prescribe maximum deflections under load expressed as a fraction of the pole height. If you need more information then just follow this link.

December 2012: Cadfil launches Options for Stress analysis of filament wound tubes

Cadfil Tube Stress Analysis - Modulus/Winding Angle Output E-Glass/Epoxy
Filament Wound Tube Stress analysis, E-Glass/Epoxy - Modulus V Winding Angle

Many years ago when we started working in the field of filament winding it was apparent that some simple tools for laminate analysis of tubular filament wound components would be highly useful. There are many complex and capable software analysis systems available commercially however for day to day engineering some quick calculations are what is needed during the initial feasibility of a project. The simple questions of what diameter do I need, what wind angle should I use or how thick should it be, are the first questions that need to be answered. We developed such software and have used it for our own calculations for many years. Following frequent requests from customers we have updated the user interface and created user documents to allow this software to be made available as part of the Cadfil filament winding software systems. This is an exciting development and for a short time this options is available as an upgrade for existing Cadfil customers at a special rate,

May 2012: Cadfil in Brazil

We are highly delighted to announce a new partnership with Korthfiber of Sao Paulo, Brazil for sales and technical support of Cadfil software in South America. Korthfiber will be offering the full range of Cadfil products as well as their own Multi-axis filament winding machines. Korthfiber evaluated other filament winding software but found Cadfil to be the most user friendly and accurate, to quote their proprietor "What impressed us with Cadfil was that every trial we did was right first time!" For information on Korthfiber go to www.korthfiber.com

April 2012: Cadfil/Nastran Interface Added

Manually setting up material thickness and angles data for Finite Element Modelling (FEM) for filament wound components is very time consuming so automating the task is a big advantage. The linked PDF presentation shows the process of creating the FEA Model from Cadfil, it is quick and simple. Cadfil outputs shell element model with a full laminate description for each elements. The user is able to adjust the mesh size/density prior to exporting the data from Cadfil. A Nastran Bulk data file is created complete with GRID, CTRIA6/CQUAD4, COORD2R, PCOMP and MAT8 cards to fully describe the shape and laminate structure and orientations. PDF download.

We have been pleased to contribute to COMPOSITE FILAMENT WINDING Edited by S.T. Peters and published by ASM International (ISBN-13: 978-1-61503-722-3). Because of our acknowledged expertise in advanced filament winding software we were invited to provide a chapter entitled "Programming Techniques, Computer-Aided Manufacturing, and Simulation Software".

THIS IS THE FIRST CONTEMPORARY BOOK to treat filament winding with a focus on automation. The purpose of this book is to provide detailed procedures for automated filament winding for complex shapes, to chronicle the progress that has been made in robotic filament winding along with ancillary processes that support the deposition process. It is also to show what has and what can be done to advance the process and science of low-cost composite fabrication by filament winding.

Cadfil wins JEC Asia Innovation Award (external website)

Category: Process

Design and process development of non axi-symmetric four-axis integral filament winding of double-‘D’-shaped, all-composite road tankers.

Award-winning design
The advanced Cadfil Software for Non-Round
Sections played a key role in the development of
these Fully Wrapped Non-Round road tankers.

Road tankers are used all over the world for transportation of water, edible oil, milk, chemicals and petroleum products. Traditionally, road tankers have a steel or aluminium body, with or without rubber lining inside. Metallic tankers are heavier with 12 to 15% of the liquid they carry and the rubber lining requires frequent repair and relining every four years.

Unlike pressure vessels, road tankers for transportation of liquids under gravity are made of double-‘D’-shaped cross-sectional profiles in order to keep the overall centre of gravity low for better stability and vehicle road holding. No winding process for such non axi-symmetric profiles with integral-end dome winding has been developed so far. This innovation is intended for the filament winding of such tankers.

These composite tankers are more resistant to water and many chemicals. Their high strength-to-weight ratio and stiffness-to-weight ratio make them lighter and long lasting. They offer 45% weight saving over a steel tanker. The joint-less winding of shell in an automated machine makes production faster and the product stronger. Two tankers can be made in a day vs. several days for steel. A factor of safety of six or above is guaranteed without any resin leakage.

In September 2008, the AMC approved the launching of the tanker for field application. Negotiations are in process with a major truck manufacturer in India for marketing the product with annual initial sales of 500 tankers. Jump to Road Tanker Winding Video(non-round)
