Effect of cogon grass powder (Imperata cylindrica L. Beauv) composition and particle size on physical and mechanical properties of unsaturated polyester resin particle board products

Compression molding has produced quartz-reinforced polyester composites (QPCs) weighing 10 to 40 per cent quartz relative to the weight of unsaturated polyester resin. Synergistic changes were made in the composite properties and were superior to those of the individual components. The composite's physical and mechanical properties such as bulk density, water absorption , tensile strength, flexural strength, hardness have illustrated the competency of the composite being developed. It was found that for the resultant composite examined, the percentage of water absorption is very small. However, when quartz content were increased, water absorption grew very slowly. Enhancement of mechanical properties strongly corresponds to strong adhesion force of quartz with the matrix and it influenced by well-disperse quartz particles on the whole surface of composite. This paper also performed thermal characterization of the composites. Because of these remarkable properties, as prepared composite can find applications in packaging, fuel cell, solar cell, structural materials and households purposes.

There is a lot of glass fiber reinforced plastic (FRP) waste every year. Its low utilization rate and serious secondary pollution cause many problems. In this paper, FRP waste was added to enhance unsaturated polyester resin based artificial marble. The effects of FRP waste content and its particle size on the mechanical properties of artificial marble were discussed. Results show that the FRP waste content and its particle size are closely related to the mechanical properties of artificial marble. The artificial marble with FRP waste particle size of less than 0.075 mm and content of 12.5 wt % got the best mechanical properties, whose flexural strength was 23.72 MPa and compressive strength was 79.13 MPa, increased by 75.8 % and 128.1 %, respectively, compared with the strength of artificial marble with no FRP waste.

Bending Modulus

E-glass fiber mat reinforced Unsaturated Polyester Resin (UPR)-based composites were fabricated by conventional hand lay-up technique. The fiber content was varied from 5 to 50% by weight. Mechanical properties (tensile and bending) of the fabricated composites were investigated. The tensile strength (TS) of the 5% and 50% fiber reinforced composites was 32 MPa and 72 MPa, respectively. Similarly, tensile modulus, bending strength and bending modulus of the composites were increased by the increase of fiber loading. Interfacial properties of the composites were investigated by scanning electron microscopy (SEM) and the results revealed that the interfacial bond between fiber and matrix was excellent.
