Limitations
The model proposed in its current state doesn’t provide
any means to check the fiber orientation which
drastically affects composite material property
Resin application is to be done manually
The holding mechanism proposed is slow due to use of
threads but can be easily changed to other linear
actuators

Future Developments
Incorporate a sensory system to check fiber orientation
as it directly affects the composite strength and sorting
out incorrect pieces
Device the mechanism which would allow differently
oriented fibers to be processed serially so that mixed
type composites can be produced

Conclusion
The mechanism operates slowly but satisfactorily.
It was found that individually the components performed as
required but in integrated form synchronization difficulties exist
The methodology can be easily adopted is simple and adaptive
for manufacturing
