Undercutting -
a condition that can result in flow lines, side and top cracking, and
entrapment of large bubbles in the centre of a foamed composite.
Underfill -
insufficient pour of a chemical mix resulting in not filling a mould
fully.
V
Velocity balance -
a lead-lag problem under some conditions of metering and
mixing machine operations in which pressures are balanced exactly.
Vertical cutting saws -
special cutting bandsaws in which the blades used for
cutting are in the vertical plane.
Vertical pour -
pour-in-place operations.
Viscous -
a flow condition of any fluid or mix more resistant to flow than water.
W
Water absorption -
degree of water absorption if composites are exposed to the
weather.
Weathering
-
when a material is exposed to the weather.
Y
Yield point -
in compression or tension loading of a composite sample, the point at
which permanent deformation takes place.
Yield strength -
the force required to bring a specified sample of a composite to the
yield point.
Z
Zones
-
in processing machines, there are different zones such as a feed zone and
metering zone.
