Abstract

Stone wool is one of the examples of mineral fibre. It is an inorganic fibrous substance produced by steam blasting, and followed by cooling. Amphibolite is the main component of stone wool. Besides, stone wool is also an insulating material. The feature of all insulating materials share is their low thermal conductivity factor λ, usually lower than 0.1 W/Mk. Meanwhile, polyethylene (PE) is a thermoplastic polymer consisting of long chains of the monomer ethylene. PE is classified into low density polyethylene (LDPE) and high density polyethylene (HDPE). Review passed work by other researchers, it is found that only few researchers do research on the stone wool as reinforced fibres, and none of them used stone wool as reinforcement for polymer matrix composite (PMC) and analyze its mechanical properties. Thus, my study is aiming to characterize the mechanical properties of stone wool reinforced HDPE with various stone wool weight ratio, which is between 0 – 40 wt%. Mechanical tests such as tensile test, flexural test, and shore hardness test are used to characterize the mechanical properties of the stone wool reinforced HDPE, while scanning electron microscope (SEM) is used to study the microstructure. Software CES EduPack is used to propose products for stone wool reinforced HDPE composite according to its mechanical properties. From the results, the 20 wt% stone wool loaded specimen has the best performance in tensile test, while the 40 wt% has the best performance in both flexural test and shore hardness test.
