- •
The (BH)max and DOA are increased by 32.2% and 61.3% at the space rate of 25%.
- •
The problem of mould damage is solved and the mould life is improved greatly.
- •
The preform density is selected above 3.60 g/cm3 to ensure the integrity of preform.
- •
25% is the best space rate to reach maximum (BH)max, DOA and density at 3.98 g/cm3.
