Maximum mechanical properties of hybrid BGRP composites from previous studies.

No.	Resin	Hybrid	Fabrication Method	Tensile Strength (MPa)	Flexural Strength (MPa)	Impact Strength (kJ/m2)	Remark	Ref.
1	PP	Filler	Extrusion	31	-	-	Increasing basalt content led to a decrease in tensile strength.	[20]
2	Epoxy	Filler	Hand layup	273	497	426	The addition of a large amount of basalt reduced the impact strength.	[21]
3	Polyester	Laminate	Hand layup	78	175	-	Mechanical properties of BGRP composite are lower than BCRP laminates.	[22]
4	Epoxy	Laminate	Vacuum begging	448	-	-	The tensile strength of BGRP composite was lower than GFRP laminates.	[24]
5	Polyester	Laminate	Hand layup	293	302	192	The stacking sequence of BGRP improved mechanical properties.	[23]
6	Epoxy	Laminate	Vacuum begging	225	195	212	Increased glass fiber increased the tensile strength (BGRP < GFRP composite).	[25]
7	Epoxy	Laminate	Vacuum begging	-	-	4	Hybrid BGRP had a lower impact strength than the BFRP composite.	[26]
8	Polyester	Laminate	Hand layup	270	-	946	Hybrid BGRP offered the highest value of mechanical properties compared to GFRP and BFRP laminates.	[28]
9	Polyester	Laminate	Hand layup	246	-	204	Hybrid BGRP laminate had the highest tensile strength.	[29]
