Paragraph starter

Research by Wang and Xu (2015) demonstrated that the structural strength of shelters can be significantly enhanced by utilizing glass fiber-reinforced epoxy (GFRP) composites over aluminum. Their finite element analysis indicated that specific fiber orientations, particularly ±45° and 0°, are crucial, with external ±45° layers proving most effective. This approach not only improves structural integrity but also offers substantial weight reduction, providing a strong rationale for adopting advanced composite materials in shelter design.
