 Reinforcement of polymers with particles to enhance their mechanical properties for various applications cannot be over emphasized. Hence, the microstructure and mechanical behaviour of polyester resin matrix composites reinforced with pineapple leaf particles was studied in order to develop an engineering material for industrial applications. Pineapple leaf particles treated and untreated with NaOH were separately blended with unsaturated polyester resin. 1 g of catalyst and 0.5 g of accelerator were added to the mixture to achieve a homogeneous interfacial interaction. The composites were made by mould casting and their microstructure and mechanical properties were evaluated. The NaOH treated pineapple leaf particles reinforced composite exhibited the highest tensile strength of 98.73 MPa at 15 wt. % and impact energy of 20.73 J at 20 wt. %. Microstructure showed a fairly uniform distribution of the pineapple leaf particles in the polyester resin matrix coupled with the strong interfacial bonding of the filler and matrix as the major factors responsible for the enhancement of the tensile strength and impact energy of the composites.

Composites have become the chosen material for new engineering materials specially in the areas of aerospace applications, military weapon and automotive components, due to its unique mechanical properties, like: high strength weigh ratio, extreme thermal shock resistance, low coefficient of thermal expansion, oxidation and wear resistance Polyester resin matrix composites reinforced with coconut fibers are being utilized as replacement synthetic fiber in fiberglass products. The high price of synthetic fiber, which is use as fiber reinforcement on fiberglass products, makes its products price become expensive. One alternative to reduce its prices is by replace fiber synthetic with other fiber, which have similar mechanical properties but cheaper and still not abandon regional potency. Coconut fiber are regional potency that still not used optimally, moreover they often considered as waste that doesn’t have economic values. These research use experimental methods with control variables are percentage of coconut fiber and polyester resin by Planar and Random orientation fiber. Specimen testing makes by hand lay up fabrication. The research result shows that the optimum composition is on 40% fiber: 60% polyester resin, with value of tensile strength is 20.75 N/mm2 and value of strain is 0,7 % by planar orientation fibers, while optimum composition on random orientation is on 30% fiber: 70% polyester resin, with value of tensile strength is 30.73 N/mm2 and value of strain is 1.4%.

 The efficacy of reinforcement of polyester resin matrix composites with agro waste particles to effect improvement on the disadvantage of low mechanical properties for optimal performance was studied. 5-25 wt. % of coconut shell, periwinkle shell, and cow bone particles were applied in reinforcing unsaturated polyester resin matrix by mould casting and the microstructural and mechanical characteristics of the composites were evaluated. There was uniform distribution of the agro waste particles in the polymer composites matrix from the scanning electron microscopy (SEM) result. The hybrid composite at 15 wt. % reinforcement demonstrated the highest mechanical properties in terms of ultimate tensile strength (66.73 MPa), flexural strength (76.76 MPa), hardness (87.76 BHN), and impact energy (23.16 J). This shows the efficacy of hybridisation and the high potential of the composite for wider applications.

Reinforcing Filler

An experimental study on the manufacture of polyester resin matrix composites using basalt powder as a reinforcing filler has been carried out. Basalt is a volcanic igneous rock often found in East Lampung and has not been utilised. Basalt is chosen as a reinforcing filler because basalt has advantages such as wear resistance, corrosion resistance, resistance to chemical reactions, and high hardness. The research parameters used were variations in the size of the basalt powder, the composition of the polyester resin matrix to the basalt powder, and the percentage of the catalyst. All parameters were mixed according to the research procedure, and all samples were formed under pressure 20 kN. Tensile test results showed the highest value of 0.961 kgf/mm2 from 60 mesh-25% polyester-1/30 catalyst variation parameter. The highest compressive strength value of 28.331 kgf/mm2 was obtained from the various parameters of 270 mesh-20% polyester-1/20 catalyst and 270 mesh-25% polyester-1/30 catalyst. The results were not much different from those, which is 27.787 kgf/mm2. The use of 1/30 hardener catalyst to the amount of polymer by 25 %wt gives optimal results on the characterisation material testing. However, the effect of the filler grain size gave different results for each test carried out. Therefore, to obtain the desired mechanical properties when using basalt rock powder as a filler, it is necessary to pay attention to the correct grain size.
