Fernando et al. [88] studied on the timber laminate reinforced basalt fibre on
tensile loading to improve the behaviour of the timber as a structural material. The

incorporation of BFRP with timber significantly increases the axial stiffness and

strength up to 26 and 65 %, respectively in comparison with pure timber laminate.

2.12 Flexural Properties of Fibre Reinforced Polymer Composites

Lopresto et al. [86] studied on basalt/epoxy on the flexural strength and
modulus in comparison with E-glass/epoxy. Based on fracture surface analysis, E-

glass denoted a compressive failure mode while basalt showed a tensile failure mode

when subjected to bending load. In addition, basalt/epoxy showed superior properties
of flexural strength and modulus in comparison with E-glass composites.

The highest improvement in the flexural strength and modulus were observed
when both layers of glass were replaced with basalt layers. The emergence of basalt

layers contributes to enhance the capability of material in resisting bending condition,

particularly on tensile and compressive loadings. It was found that the glass/basalt
