The objective of this research is to analyze the microwave power absorption properties of Unsaturated Polyester Resin (UPR) composite reinforced with micro size river-shell with an aim to figure out the new formed composites with the best microwave power absorption scenario. The composites were prepared by using river shell powder in micro-particle size as a filler material with unsaturated polyester composites. Using free-space transmission technique and within the x-band frequency range, the microwave power absorption properties were studied with varied percentages of river shell powder being loaded into the unsaturated polyester composites. River shells were introduced in an 50 microns particle size powder which was mixed in different weight percentages of 5, 10, and 15 % of a 12 cm square shape side length composite sample along with a thickness of 4 mm for each sample. The test specimens were prepared using the pre-mentioned weight amounts after mixing them with the Unsaturated Polyester Resin (UPR) compositions and in accordance with ASTM standard. Number of teste samples are four represented by pure, 5 %, 10 %, and 15 % of river-shell reinforced polyester composites. It has been found that the 5 % is the case when maximum power absorption presents higher levels than other loading percentages. Therefore, such kind of composites can be established under focus in those applications at which their trends is about necessity and importance of microwave power absorption.

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.
