This course will cover all of the options found in the Composites Design and Composite Grid Design workbenches. The first portion of the book will focus on the design options available within the Composite Design workbench. The second portion of the book will delve into the manufacturing side of composite parts and how they will be created. Finally, the grid method will be discussed in the Composite Grid Design workbench. In order to have access to the Composites workbenches, you will need to turn on the CPE and CPM licenses under Tools, Options, General, Licensing.

Introduction, Page 2©Wichita State UniversityCATIA Composites CATIA® V5R19 Ply Creation

This section will discuss creating and modifying plies both automatically and manually. The plies created here will represent the actual plies that will be necessary in order to build the composite part.

Importing a Laminate

When a zone is defined, the laminate can be specified by manually entering the number of plies in each direction. Rather than entering each laminate definition manually, the definitions may be imported from an excel spreadsheet.

Open the Importing a Laminate model. The zones have already been defined on this model. It should appear as shown.

Ply Creation, Page 33© Wichita State University

Double select on Zone.1 in the specification tree. The Zone Definition window appears. Switch to the Laminate tab. Notice nothing has been defined.

Select Cancel. The second zone laminate definition is not specified either.

Open the Import Laminate Definition document. This is a predefined excel spreadsheet containing the laminate definition. It should appear as shown.

The material, directions and plies can all be modified for each zone within the excel spreadsheet. Keep in mind, the composite parameters defined in the part, must match the spreadsheet. If you have directions of 0, 45, -45 and 90 in the spreadsheet, you must have those same directions in the composite parameters.

Close the spreadsheet.

Select the Import Laminate icon. The Import Laminate Definition window appears.

Select the Browse icon. This will allow you to define the correct spreadsheet to use to define the laminate.

Browse to the models directory and select the Import Laminate Definition document and select Open.

Select OK.

Double select Zone.1 in the specification tree and switch to the Laminate tab again. Notice the laminate definition is defined.

Select OK.

The other zone is also defined. If you decided to make a change to the laminate definition at this point, you could either do it manually or you could change the spreadsheet and then import the laminate again.Stack Up File From Zones

This option allows you to create a stack up file based on predefined zones. The file will contain the stacking order of the plies within the composite part. This provides a way to look at the way the plies will be created before actually creating them.

Select the Stack Up from Zones icon. The Stack-up file from zones window appears.

Zones to be taken...Specifies the zones that will be referenced in the stack up

Browse button Specifies where the file will be saved

Open stack-up file...Specifies that the newly generated file will automatically be

opened upon creation

Zone Connections Includes the zone connection sizes in the file

Select the Browse icon and go to a location in your area. Name the file Stack Up From Zones and select Open. This specifies where the file will be stored.Turn on the Open stack-up file after creation option and select OK. The stack up file is created and should be opened automatically.

The spreadsheet shows all of the plies that would be created based off of the defined zones at this point.

Save and close both documents.Stack Up File From Core Samples

This option allows you to create a stack up file and core sampling based on predefined zones and existing plies. The file will contain the stacking order of the plies within the composite part. The core sampling file displays the location of the core sampling itself for each zone.

Open the Stack Up File From Core Sampling document. The plies have already been generated for this file.

Select the Stack Up File from Core Sampling icon. The Stacking from core sampling information window appears.

Core samples file Specifies where the core samples file will be stored

Stack up file Specifies where the stack up file will be stored

Core samples prefix Defines a prefix for the core samples that will be created in

the model

Select the Browse icon for the Core samples file and go to a location in your area. Name the file Core Sample and select Open. This specifies where the file will be stored.

Select the Browse icon for the Stack up file and go to a location in your area. Name the file Stack Up and select Open. This specifies where the file will be stored.

Key in CS for the Core samples prefix and select OK. The files are generated along with core samples in the model. The locations of the core samples are shown in the display.

The core samples should appear as shown in the specification tree as well. These will be discussed in more detail later on.

Go to your area and open both the Core Sample file and the Stack Up file. The Core Sample file should appear as shown.

The Stack Up file should appear as shown.

Save and close the documents.

Plies Creation From Zones

This option automatically generates plies based on predefined zones.

Open the Plies Creation document. All of the preliminary design has already been done on this model.

Expand the Composites PD branch and hide the Connection generator branch in the tree. This will make it easier to select the wireframe elements later on in this exercise. Select the Plies Creation from Zones icon. The Plies Creation window appears.

plies

Create plies in new group Specifies a the plies will automatically be created in a new

group

Create plies from Zones...Specifies that taper will be used in the creation of the plies

within the transition zones

Create full plies and...Specifies that the plies will be created with the corresponding

edges to be staggered. The ETBS can be used to define limit

contours for modifying the plies later on.

Staggering Data When using the Create full plies and ETBS option,

you may choose to generate a staggering data file

containing all of the edges to be staggered

Turn on the Create plies in new group option and be sure the Create plies from Zones with Taper option is active and select OK. The plies are generated. Two new branches appear in the specification tree.

The Stacking branch contains the new group and all of the plies. The geometrical set contains datum curves that represent the outside edges of the plies.

Expand the Stacking branch. It should appear as shown. Notice the plies are contained within a plies group. The order of the plies under the Stacking branch determines the order that they will stacked on the definition surface.

Ply Creation, Page 41© Wichita State UniversityThe staggering locations are displayed on the surface as well.

Select Ply.1 in the specification tree. Notice the ply highlights in the display.

Each ply is represented in the specification tree and its outline will highlight in the display if you select it from the tree. By default, the plies are created from smallest to largest. This is typically not how you will want them to be ordered. Later, you will actually explode the plies so you can see them as well as reorder them.
