Glossary

A

actual difference between the direction of a ply and the delta or deviation angle.

C

core insert enabling to stiffen the part.
core sampling piercing of the part at one point to get the laminate.

D

 
deformation a producibility analysis mode based on the angle between the two vectors of the fiber mesh.
delta angle of deviation computed when performing a producibility analysis, that is angle between the transferred theoretical rosette and the actual fiber direction (along the X axis).
deviation a producibility analysis mode based on the angle between the x axis of the transferred rosette and the x axis of the fiber mesh.
draping direction direction whereby the plies are laid on the mold.


With the draping direction shown, material is applied on the upper/concave side of the surface. If you reverse the draping direction, material will be applied on the lower/convex side of the surface.
Note that the order of pPlies from top to bottom in the stacking corresponds to the draping direction arrow from tail/base to head/tip.

E

EEOP Engineering Edge Of Part: engineering outer boundary of the plies.
EOP Edge Of Part: outer boundary of the plies.
ETBS Edge To Be Staggered: common edge between two adjacent zones.

I

IML Inner Mold Line: top surface of the Composites part.
ITP Imposed Thickness Point: connection point between transition zones, and zones on which the user wants to impose a thickness.

L

laminate number of layers per association material / direction for one zone.

M

MEOP Manufacturing Edge Of Part: manufacturing outer boundary of the plies.

P

ply piece of fabric.
producibility simulation of the fibers behavior to detect manufacturability problems.

R

rosette defines the axis (X, Y, Z) in which the directions are stored.

S

sequence manufacturing notion. Set of plies that the machine puts on the mold in one path.
stack-up file file containing the stacking order of the Composites part.
staggering ply drop-off to avoid ply build-up.
strategy point point used to start the circular propagation of the fibers in the producibility tool.

T

transition zone zone defining the geometric area of the ply drop-off between two zones.

Z

zone conceptual definition of the Composites part. Geometrical area in which the laminate is constant.
