Composicad is a new kind of software for filament winding.
Composicad focuses on the whole part, rather than the
individual wound layers. Using Composicad to program can save
significant amounts of time for the most common filament wound
objects - pipes, tanks and figures of revolution.
The Metal version of Composicad has seven individual
- Bronze - for pipes and tubes
- Titanium - for spars
- Iron - for elbows and ducts
- Cobalt - for Tee shapes
- Silver - for tanks and vessels
- Gold - for figures of revolution
- Chromium - for post processing fiber paths
Depending on the license, individual packages may or may not
be installed. Packages may also have one or more options:
- FEA mesh output option for all packages except Cobalt
- Simulation option for all packages
- Script option for all packages
- Database option for all package
- From 1-8 machine setups as well as the No Machine output
- 2,3,4,5,6 axes configurations as well as robotic
- Translation of Menus and dialogs
- Increased number of lamina and/or materials
The title of the main dialog shows the various packages and
options which are installed.

The Composicad Approach
To make a filament wound part using Composicad is straight
- Define the material to wind
- Select the part type - pipe, vessel,
figure of revolution, spar, duct. tee, or post
- Define the original mandrel shape and general part
- Define the laminate sequence to
be wound including transitions
- Select the machine output to
Composicad stores all of the information it is using in a
file called the part (or project) state file. This file is
named ccm_state.prj. It is normally stored in the directory
from where Composicad is being run. See Other Options for more information
about this state file.
As you enter information for your part (project) Composicad
will calculate everything it can based on the information it
has. Thus as you enter the part information, Composicad is
calculating the fiber paths, the machine motions, the new
mandrel shape and many other kinds of data that it needs.
You can save (and load) the program state as a Project file
using the Load and Save Menu Items.
This file contains all of the information associated with the
part. Normally, Composicad only generates a few files - the
state file and Project file, and the required machine control
output files (in the format for the specific machine
controller). Other files may be optionally generated if
The graph above shows the way that data flows through
Composicad. Because Composicad is parametric (all calculations
are based on the previous data calculated), it is very easy to
make changes to the part and then Composicad recalculates all
of the data needed to wind that part.
A key to this process is the new mandrel shape generator. As
a part is being wound, the shape of the part is changing, due
to the thickness of the material being wound onto the part.
Composicad uses a several different algorithms to calculate
each new mandrel shape. The choice of the method is determined
by what data is needed.
