Abstract
Composite materials are able to improve the system performance by reducing redundancy. Different materials with the best characteristics can be combined to create a new material. In this study, a composite material was manufactured with glass fibre and inorganic mineral additives. It was aimed to produce strong, light-weight and flame retardant cable trays. Within this context, glass fibres were used to strengthen the mineral reinforced cable trays. Mechanical and flame retardant properties of composites were examined according to glass fibre loading and micro-nano size distribution of the mineral. Composite samples were prepared by adding glass fibres and huntite/hydromagnesite minerals with different ratios to poly vinyl chloride (PVC) matrix. Flame retardant property was studied through the limiting oxygen index (LOI) test. Mechanical effects of the glass fibre additives were investigated as a main objective of this work. It was observed that glass fibre additives improved the mechanical properties of the composites. Tensile strength increased from 38.4 to 65.8 MPa by adding 30% glass fibres.
