“…The use of pristine dolomite was proved to not significantly improve the performance of polymer composites, particularly mechanical performance. Therefore, there are researchers who used a physical approach to modify the physical aspect of dolomite, such as reducing its particle size and agglomeration through the application of mechanical energy (milling), ultrasonic force, and shear energy [9,11,12,[69][70][71]. This modification was proved to assist in the better dispersion of dolomite in the polymer composite, promoting better interaction and adhesion of dolomite and polymer.…”

“…Research findings indicate that the polymer composite will show optimum performance when the dolomite loading is below 30 wt%. This is due to the agglomeration of dolomite particles in the matrix phase when the filler is added at high loading [13,69,70]. For instance, Syed Bakar et al have observed clear agglomeration of dolomite particles in the SEM morphology image of the tensile fractured surface of their composite sample with 50 wt% dolomite [71].…”

Polymers are being used in many applications all around the world. However, there are some drawbacks in the properties of polymers that could hamper their usage in certain applications. Therefore, a new material polymer composite was introduced. A polymer composite is a polymer-based material with the addition of a filler. Many researchers have reported the improvement in the properties of a polymer when a filler was introduced. This helps minimize the disadvantages of using a polymer. As a result, polymer composite products can be used in many industries, such as automobile, aerospace, biomedical, and packaging. Fillers derived from natural minerals, such as dolomite, are among the best reinforcement materials for polymeric materials because they are plentiful and low cost, have high rigidity and hardness, and even have tailorable surface chemistry. The use of dolomite as a filler in a polymer composite system has gained increasing attention in recent years after researchers successfully proved that it is capable of improving the mechanical, physical, and thermal properties of various polymeric materials. However, chemical or physical treatment/modification of raw dolomite is needed in order to prepare it as an efficient reinforcing filler. This procedure helps to improve the performance of the resultant polymer composites. This article reviews the usage of dolomite as a filler in a variety of polymeric materials and how it improved the performance of the polymer composite materials. It also highlights several methods that have been used for the purpose dolomite’s treatment/modification. Furthermore, the role of dolomite as a co-filler or a hybrid filler in a polymer composite system is also discussed, revealing the great potential and prospect of this mineral filler in the field of polymer composites for advanced applications.

The natural and synthetic fibers are combined in a single composite to achieve a balance between the desired strength and cost considerations. In this study, the vacuum resin transfer moulding process was used to prepare an epoxy‐based composite. The composite consisted of grewia optiva as the natural fiber and glass fiber as the synthetic fiber, both with a fixed weightage of 10 %. Dolomite was used as a filler with varying content (0 %, 5 %, 10 %, and 15 weight %). The physical, mechanical, erosion wear and morphological behavior of the epoxy‐based composite were investigated. The inclusion of dolomite filler significantly increased the composite hardness and impact strength but reduced its tensile and flexural strength. At a dolomite filler content of 10 weight %, the erosive wear was reduced, while it increased at higher dolomite filler contents. The composite was examined using the L16 array, and the minimum wear rate was observed at an impingement angle of 30°, a velocity of 10 m/s, and an erodent size of 150 μm. Morphological studies were conducted to explore the possible mechanism for the variation in erosive wear at different dolomite contents in the hybrid composites.

Dolomite has great potential to be employed as filler or nanofiller in polymer composite/nanocomposite system. However, the research on dolomite as filler or nanofiller in polymer composite is still immature, requiring further investigations on how to optimize the dispersion of the dolomite in the polymer matrix, thus improving its properties. Particle size reduction of dolomite can be an efficient approach to increase its surface area and facilitate its dispersion and distribution within polymer matrix in order to develop homogeneous composite/nanocomposite system. In this study, the dolomite in pulverized form was obtained from Perlis Dolomite Industry, Malaysia with the average particle size of 150μm. In order to reduce the size of this dolomite, we have initially employed the planetary ball milling method. Results indicate that the particle size of dolomite has been reduced from 150μm to 2μm after subjected to ball milling process. This shows that upon ball milling procedure, the size of dolomite particle is still in micronmeter. Next, the ball milled dolomite was subjected to tip-sonication process to obtain dolomite in nanosize range. Several tip-sonication parameters, which were; amplitude and number of sonication repetition were applied in order to select the best parameters that can produce the finest dolomite powder. SEM and TEM were used to characterize the microstructure of the raw dolomite and the size reduced dolomite. Our results show that when the ball milled dolomite was tip-sonicated, much smaller particle size was obtained. Dolomite with the smallest particle size (~200nm) was obtained when the tip-ultrasonication was performed 3 times at amplitude of 50. These findings indicate that the combination of ball milling and tip-sonication is an efficient method to produce very fine dolomite particles, up to nanosize range. Furthermore, it is a clean, simple method and not involved any toxic and harmful chemicals.
