This version is fast, up to 10 times faster! This is the result of a new flow front tracking algorithm, which is not only very clever, but also very robust and accurate. There are also several other enhancements, like more possibilities to add sensors, custom material models and boundary conditions. We also made some improvements to the graphics and SALT language and libraries.

29 March 2021: RTM-Worx 3.10 released!

With improved 3D rendering, more options for shaded & contour plots, the possibility to add custom viscosity models and boundary conditions in SALT, better error reporting and several other enhancements, version 3.10 is the best RTM-Worx ever!

8 July 2019: RTM-Worx 3.9 released!

The most important changes and additions were made to the interactive environment: new commands in geometry (keypoint, curve, surface and region) editors, hit testing & selection of regions by the mouse, and rotate and zoom now anchor at the point under the mouse cursor. There have also been some enhancements to SALT, primarily to support programming larger applications.

JEC World 2019, 12-14 March, booth 5E80

Polyworx is exhibiting in the Holland High Tech pavillion, Hall 5 - Booth E80. Together with Inholland University for Applied Sciences and Twenco, we will demonstrate the application of augmented reality with model-based process monitoring.

METS 2010, Amsterdam RAI, 16-17-18 November, 2010

Polyworx will exhibit in booth nr. 11.539 , in cooperation with Brands Structural Products. RMK in Tuzla, Istanbul, Turkey established a world record in April this year: infusion of 6.3 tonnes of vinylester resin in a single shot for the Oyster 125' hull and we developed the technology to make it work! First time right and due to the experience that RMK built up with infusions for the Oyster 100', it was not only the largest, but also simply the best infusion they have done. We have also infused two North-Line 42' hulls for Jachtbouw Zevenhuizen, not just a sandwich, but with all the stiffeners included in a single shot, saving two weeks time in the mould. Pay us a visit if you want to be at the leading edge of infusion technology as well and are interested in doing so with our support to eliminate your risks, either by licensing our flow simulation software (with proven accuracy, so it can replace all your in-mould trials by injections on screen) or using our consultancy services. If you still need to decide whether infusion is a feasible technology for your project, or if you are building a large yacht and have to choose between aluminium or composite, we can offer you a free cost estimate that includes labour and materials. Or if you are just curious what is going on: we are in booth nr. 11.539 and will be happy to tell you all about it!

JEC Composites Show 2010, Paris Expo, 13-15 April, 2010

Polyworx will exhibit at the JEC Composites Show, booth nr. N82. We finished the core of our new SALT platform for high level scripting in RTM-Worx! In addition, we have been quite busy redefining the meaning of 'large infusions', with the Oyster 100' and 125' projects (check out the Oyster 100' infusion pictures ) and developed a technology to infuse structures of more than 6 meters high in multiple shots without removing the bag! Want to know more? Pay us a visit in booth N82.

METS 2009, Amsterdam RAI, 17-18-19 November, 2009

Polyworx will exhibit in booth nr. 01.404, in cooperation with Brands Structural Products. Come to our stand and see how the largest parts ever infused worldwide have been done! We also can show pictures now from the infusion of the Oyster 100' hull (3600 kg) and deck (1250 kg), a project we are doing for RMK in Tuzla, Turkey. Not only large boats, but also smaller boats can be done economically with infusion. We developed a calculation method that allows us to make close estimates of the material cost and manhours for an infusion project. If you want to be up to date with state of the art in infusion technology, make sure you pay us a visit!

• Trailing arm by the Dutch Aerospace Laboratories (NLR) in cooperation with SP Aerospace and Vehicle systems, Eurocarbon and MSC;
• Infusion of a windturbine rotorblade by LM Glasfiber A/S - state of the art Vacuum Infusion technology and a very nice example what can be done with the combination of RTM-Worx and the MSC Laminate Modeler;
• Infusion of several yacht hulls and decks: Standfast 43' (carbon/epoxy), Prinz 40' fly (glass/polyester sandwich), Classicon Yachts 20 meter powerboat hull (glass/epoxy) and more!

More about those projects will be added to the website in the near future. In the meantime, check out our posters/handouts for some illustrations:

Prediction of Product Properties

At the JEC Composites Show in Paris, April 2003, MSC Software and Polyworx have presented a new software solution that allows you to decrease costs and increase the accuracy of your parts!

• Import the model created in MSC Laminate Modeler in RTM-Worx to save lots of time and take the fabric deformation into account (as it will change fabric porosity and permeability);
• Export results from the RTM-Worx temperature & curing analysis to MSC Nastran for accurate prediction of deformation due to thermal stresses! This very powerful capability does not just give you the ability to predict springback, but also to study the effect of process parameters and increase the accuracy of your parts!

Anaglyph has launched the new Laminate Tools (LT) 2.0. Using LT in combination with RTM-Worx greatly enhances the communication with other engineering software packages.

Black Metal or Black Art? 2003

A Review of Virtual Product Development Techniques for Composite Materials & Components
Wednesday, March 12, 2003
Williams F1 Conference Centre, Grove, Oxon, UK

Hosted by MSC.Software, "Black Metal or Black Art? 2003" is a free technology seminar designed to provide a state of the art review of virtual product development techniques for composite materials and components. Polyworx will contribute with a presentation of the advanced process simulation that is possible with the combination of the MSC Laminate Modeler and the Polyworx RTM-Worx software, which will be illustrated with applications in boatbuilding (the Maxi Jena 80' carbon/epoxy racer) and vacuum infusion of wind turbine rotorblades by LM Flasfiber A/S, Denmark.

Controlled Vacuum Infusion Technology

Because we provide software tools for new technologies, it is very important that we have knowledge of the injection process itself: it is the most important component of our support. From there, it is a very small step to actually implement the technology for our customers. This is exactly what recently happened with the Controlled Vacuum Infusion technology. Right now, we are doing several projects, which range from extended support in combination with a (temporary) license to the implementation of the technology to produce large composite parts (epoxy, polyester, vinylester resins and glass, carbon and kevlar reinforcement) - which includes knowledge transfer, testing of materials, measuring the permeability of the reinforcement, assistance with acquisition of equipment and materials, developing the infusion strategy and coordination of the first infusion(s).
