Influences of Various Thermal Cyclic Behaviours on Thermo Adsorption/Mechanical Characteristics of Epoxy Composite Enriched with Basalt Fiber

Exposure to advanced materials with unique thermomechanical characteristics has fulfilled the requirements of automotive, marine, and structural industries. The current research investigates the thermal adsorption and mechanical properties of epoxy composite enriched by basalt fiber via resin moulding technique with an applied pressure of 2 bar. Hydrophobic and dynamic analyzer tests developed composite’s adsorption storage and loss modulus with 10, 30, 50, 70, 90, and 110 thermal cycles under 18°C to 150°C. ASTM test standards evaluated the effect of the thermal cyclic process on mechanical properties. The composite contained 45 vol% basalt fiber with 90 thermal cycles and found higher adsorption storage modulus, elasticity, tensile strength, and flexural strength of 9200 GPa, 80 GPa, 229 MPa, and 398 MPa, respectively. The thermal adsorption loss modulus was limited by 12% on 90 thermal cycles at 150°C compared to 10 thermal cycles.
