Abstract
Carbon Fibre Reinforced Plastics (CFRP) can offer a great deal of automobile
weight saving. For automotive applications, however, they are not used well due
to their low energy absorption and long production cycle time. Hybrid composite
laminates of Carbon Fibre Reinforced Plastics/Aramid Fibre Reinforced Plastics
(CFRP/AFRP), based on thermosetting resin, have a high strength to weight ratio
and high energy absorption capacity. When CFRP/AFRP hybrid composite
laminates will be used for the mass-produced car, it is necessary to consider the
recycling efficiency and productivity. Therefore, it is preferable to use
thermoplastics resin.
The high-speed compression moulding method using an electromagnetic
induction heating system has a big advantage for the moulding of continuous
fibre reinforced thermoplastic composites, because this thermoforming technique
could reduce the production cycle time drastically. In this study, a Carbon
Fibre/Aramid Fibre Reinforced Thermoplastics hybrid composite (CFRTP/
AFRTP) was manufactured by the high-speed compression moulding method
using an electromagnetic induction heating system, and the optimum moulding
condition and mechanical properties of CFRTP/AFRTP hybrid composites were
investigated.
An optimum moulding condition was sought by using the design of
experiments method. The factors used in this study were moulding pressure,
maximum temperature holding time, materials and stacking sequences. An
optimum moulding condition was determined from the analysis of variance by
mechanical properties. The optimum moulding condition of the CFRTP/AFRTP
