RTM-Worx

Resin Transfer Moulding Flow Simulation Software

Resin Transfer Moulding Resin Injection is a cost-effecive technology to make high quality composite parts, for large series.. Developing a new product can be a lengthy and costly process. With RTM-Worx you can do a lot of trial injections in a short time without wasting any material. Optimise the process and reduce your risks in the design phase: Optimise part injection: location of runners,

injection and venting ports. Eliminate dry spots, calculate and reduce injection time.

Assess the impact of variations in resin and fabric properties, the effect of easy flow paths and establish your process window.

Gather much more feeling for the product by simulation of a large number of different cases in combination with only a few experiments.

Use the simulation in combination with a simple strip injection experiment to measure permeability of the reinforcement lay-up in your product.

RTM-Worx RTM-Worx is a very easy to use simulation code that uses the Finite Element and Control Volume methods to solve the physical equations that govern flow of a resin through a porous medium. Full support for anisotropic fabrics. Runners to model the resin delivery and easy

flow paths. Integrated pre- and postprocessing. Imports 3D models from STL, DXF and

PATRAN files. Interface with MSC/Patran Laminate Modeller

to take draping into account. Non-isothermal reactive extension available. Reliable, accurate and fast calculations. Built-in hierarchical archiving system. Supports SI, Metric and English units. Any combination of vector (velocity,

permeability), shaded and line contour plots (flow fronts, pressure, properties etc.). Very short learning time: be productive in one

day! You can quickly and easily add or remove runners, change the location of injection and venting ports without making any changes to the geometry of the part. This makes it possible to try out everything you can think of in a short time. You will be familiar with the product and the process before the mould has even been made!

Applications RTM-Worx has been successfully applied in RTM and Vacuum Infusion. Examples of some products for which our RTM simulation software has been succesfully aplied are: aircraft spoiler and stiffeners, and much more applications in aerospace, marine, automotive industries and building/construction. RTM-Worx has also been succesfully applied in Vacuum Infusion: yacht hulls and decks (up to 24 meter), windmill rotor blades and more.

Equipment To use RTM-Worx you will need a Pentium II 450 MHz PC with 128 MB RAM, running Windows XP, 2000 or NT4, a graphics card with 8 MB RAM, capable of displaying 1024x768 16-bit colour and a 17” monitor. A 3D accelerated graphics card (with 32 MB RAM) and a 16-bit soundcard are highly recommended.

Necessary skills and learning time Anyone who has experience with a graphical environment like Windows will be able to use RTM-Worx within one day: build a model, run the calculation, view and interpret the results. Some knowledge of the Finite Element Method and experience with CAD and/or FEM applications is useful but not required. You will benefit the most from knowledge of and hands-on experience with the process.

Polyworx We are a company dedicated to the development and support of software tools for the plastics processing industry. With more than 12 years of experience in the application of numerical modelling technology in Resin Injection, reactive transfer moulding, thermoplastic injection moulding, extrusion, die design and diffusion we build the tools that allow you to get ahead of the competition. We participate in international projects to develop and validate new applications. You can acquire a license for RTM-Worx from us, or we can carry out the calculations for you and advise you on the implementation and optimisation of your process.
