Abstract
Carbon Fibre Reinforced Plastics (CFRP) with thermo-setting resin are usually
used in aerospace applications and racing cars. However, considering moulding
time and recyclability, it is desirable to use thermoplastics resin for the matrix. In
our previous study, Non-woven Stitched Multi-axial Cloth (NSMC) was
developed as moulding semi-product of Carbon Fibre Reinforced Thermoplastics
(CFRTP). In this study, the rapid pipe moulding process of CFRTP components
by means of high-frequency direct resistance heating, in combination with
NSMC, was invented. This method allows heating of the mould surface rapidly
by using high-frequency direct resistance heating. NSMC makes the lamination
process easy, due to the fact that the non-crimp fabric of carbon fibre and the
non-woven fabric of thermoplastics resin are stitched to one sheet, so production
cycle time can be reduced. The invented high-speed moulding technique is
expected to apply to CFRTP pipes. This moulding method can also reduce
production cycle times, and therefore the cost to manufacture composite parts
can also be reduced. CFRTP pipe had been successfully moulded in the size of
300 mm in length, 47 mm in diameter and 3 mm in thickness by this moulding
method.
Keywords: carbon fibres, thermoplastic resin, pipe moulding, non-woven fabric,
non-woven stitched multi-axial cloth (NSMC), high-frequency direct resistance
heating.
