Example calculation of hybrid composite (sample B15/G15).

Weight Percentage (wt%)
Glass Fiber (wt%)	= 15 wt%
Basalt Fiber (wt%)	= 15 wt%
Unsaturated Polyester Resin (wt%)	= 70 wt%
MEKP (wt%) to UP resin	= 0.5% to UP resin
Density
Glass Fiber	= 2.2 kg/L
Basalt Fiber	= 2.65 kg/L
Unsaturated Polyester Resin	= 1.87 kg/L
MEKP	= 1.152 kg/L
Volume
Steel Mould	= 300 × 300 × 5 mm3 = 0.45 L
Glass Fiber	= 15% × 0.45 L = 0.0675 L
Basalt Fiber	= 15% × 0.45 L = 0.0675 L
Unsaturated Polyester Resin	= 70% × 0.45 L = 0.315 L
MEKP	= 0.5% × 0.315 L = 0.001575 L
Weight
Glass Fiber	= 0.00675 L × 2.2 kg/L = 0.01485 kg = 148.5 g
Basalt Fiber	= 0.00675 L × 2.65 kg/L = 0.01788 kg = 178.8 g
Unsaturated Polyester Resin	= 0.315 L × 1.87 kg/L = 0.589 kg = 589 g
MEKP	= 0.001575 L × 1.152 kg/L = 0.0018144 kg = 1.8144 g
