Abstract
Fiber-reinforced composites are highly promising materials widely used in aerospace, marine, medical, and automotive applications for their excellent mechanical and thermal properties, and improved life cycles compared to conventional structural materials. However, the understanding of mechanical behaviour of these materials at elevated temperatures is a crucial investigation in the realm of advanced materials engineering. In this study, fire-retardant fiber reinforced hybrid composite panels were manufactured by using carbon fiber and glass fiber as reinforcement and hand wet lay-up process. The short beam shear (SBS) test was conducted on the developed panels before and after exposure to various high temperatures such as 50, 100, 150, 200, and 250 ? to assess the interlaminar strength of the composites. These tests at the simulated conditions represent the thermal stresses experienced in real world applications, providing comprehensions of the ability of the composites to withstand at elevated temperatures. The composites sample showed a competent resilience to thermal aging until reached above the glass transition (Tg) temperature before experiencing a sharp drop in interlaminar shear stress due to thermal degradation. A set of characterization techniques such as FTIR, SEM, and Water contact angle (WCA) were conducted to understand the impact of thermally activated processes on the physical and chemical properties of these hybrid composites. Discoloration and reduction in wettability properties were observed for the exposed samples when the treatment temperature was gradually increased. SEM analysis revealed interlaminar fiber-matrix cracking. This study paves a new way for assessing the behaviours of fire-retardant fiber reinforced composite materials under thermal stress, particularly in applications requiring resilience against elevated temperatures.
