Physical and mechanical properties of coconut shell reinforced unsaturated polyester composites with the presence of Titanium Dioxide as additional filler

Unsaturated polyester (UPE) composites filled with coconut shell (CS) powder was prepared by compression molding technique. To improve the mechanical and physical properties of CS-UPE composites, titanium dioxide (Ti02) filler was added. CS also undergo two types of chemical treatment which were alk...
