Coconut Shell Powder (CSP) was derived from industrial Making Anti-Mosquito can potentially be used as filler in materials composite. The investigation on the utilization of CSP as filler in a polyester matrix has been done with the purpose to obtain the best CSP fillers size in Unsaturated Polyester (UPR) composites in producing the best mechanical properties such as tensile strength, impact strength  and water absorption. In this study, UPR was mixed with CSP at the sizes 50 mesh, 70 mesh and 100 mesh with comparison of CSP: Unsaturated Polyester 20:80 (w/w) by using hand lay-up method. The result of mechanical properties showed that, at a ratio of CSP: PE (20:80), the maximum tensile strength obtained is 42.558 MPa with the size of CSP 70 mesh. The test on impact strength was found that the increasing only occured with the size of CSP 100 mesh at 6083.47 J/m2. For absorption test, the highest water absorption occured at the first day,  water absorption increased with increasing the amount of filler and the most CSP  absorbed  water at 70 mesh.

AbstractThis investigation is carried out to understand the effects of water absorption on the mechanical properties of hybrid phenol formaldehyde (PF) composite fabricated with Areca Fine Fibres (AFFs) and Calotropis Gigantea Fibre (CGF). Hybrid CGF/AFF/PF composites were manufactured using the hand layup technique at varying weight percentages of fibre reinforcement (25, 35 and 45%). Hybrid composite having 35 wt.% showed better mechanical properties (tensile strength ca. 59 MPa, flexural strength ca. 73 MPa and impact strength 1.43 kJ/m2) under wet and dry conditions as compared to the other hybrid composites. In general, the inclusion of the fibres enhanced the mechanical properties of neat PF. Increase in the fibre content increased the water absorption, however, after 120 h of immersion, all the composites attained an equilibrium state.

Good Retention

Fine powder produced from coconut shells (CSP) has been found to be excellent functional filler in polypropylene, significantly increasing flexural and tensile moduli, slightly increasing tensile strength, and good retention of Izod impact strength at weight percentages less than 20 %. The research presented in this paper explores the temperature processing window for coconut shell powder filled polypropylene and the change in the rheological behavior of the polypropylene due to the addition of CSP as functional filler in this processing temperature window. The reason for the simultaneous increase in flexural modulus, tensile strength, and good retention of Izod impact behavior is also investigated

This paper concerns developing the mechanical properties of unsaturated polyester. This work involves preparing a composite material and reinforcing it using river shell particles with volume fractures of (5%, 10%, 15%, 20%, 25%). The composite materials undergone mechanical tests with regard to hardness, tensile, and impact strength. The experimental results obtained show that the addition of river shell particles reduce the original tensile strength and impact strength up to 5% wt, while the hardness is increased with increasing addition of river shell particles percent.
