    Abstract

    The main objective of the research is to create artificial wood whose have standard artificial wood quality that made by mixing portland cement-CaCl 2fluor arengata solid waste and reinforced by cantula fiber. The composite used short Arengata fiber as matrix filler and weaved long cantula fiber as reinforced. The focusing of the research at second years was characterizing the properties of composites that consist of : a. Investigation of the influenced of cantula fiber weaving space in the composite at 1 cm, 1,5 cm, 2 cm and 2,5 cm, which mixed by matrix that consist of arengata powder (80 mesh sized) - portland cement -CaCl2,- water (15 : 47,2 : 18,9 : 18,9 in composition) and pressed at 88 kg/cm 2 . the investigation has been done to get the physical properties (density, wate absorption, thermal conductivity and surface cracking) and mechanical properties (tensile sterngth, poisson ratio, bending strength, nail tensile strength, hardness and pressed strength). b. Investigation of the influenced of cantula fiber weaving angle in the composite at 0 0 , 15 0 , 30 0 and 45 0 , which mixed by matrix that consist of arengata powder (80 mesh sized) - portland cement - CaCl2,- water (15 : 47,2 : 18,9 : 18,9 in composition) and pressed at 88 kg/cm 2 . the investigation has been done to get the physical properties (density, water absorption and surface cracking) and mechanical properties (tensile sterngth, bending strength, nail tensile strength, hardness and pressed strength). c. Creating the simulation of composite strength distribution when made into a simple chair and burdened with a load of 100 kg by using the program ANSYS. The simulations was made by using the data of Poisson ratio, tensile strength and modulus of elasticity of woven composites with 1 cm spacing at the angle of 0 0 and 15 0 . The simulation was made by using the composite board which have width 10 cm and thickness variation of material from 1.5 cm, 2 cm and 3 cm All of the standard test in this research, both the shape and dimensions used ASTM standards as a reference. And the second year research has produced some of the data as follows: a. The character of cement -aren-matting cantula composite with the wide variation from 1 cm - 2.5 cm have some mechanical properties that vary as following : tensile strength ranged from 3.35 to 2.06 MPa in, modulus of elasticity ranged from 292.98 to 400.39 MPa in, Poisson ratio ranged from 0,2 to 0, 48, bending strength ranged from 15.76 to 10.22 MPa, tensile strength of nails ranged from 241.8 to 152 N, hardness ranged from 13.921 to 13,355 HB, compressive strength ranged from 43,78-69.03 Mpa. The physical properties of composite were as follows water absorption (2 hour immersion) ranged from 19.3% to 10.8%, water absorption (24 hour immersion) ranged 20.7% to 14.54%, mechanical power (depth 15 mm) ranged from 1.69 to 1.648 KW, density ranged from 1.29 to 1.47 gr/cm 3 , thermal conductivity ranged from 0.0119 to 0.0118 W/m 0 C and fracture surface showed a good interfacial bonding. b. The character of cement - aren-matting cantula composite with the angle weaving variation from 0 0 to 45 0 have some mechanical properties that vary as follows : tensile strength ranged from 3.35 to 1.98MPa, modulus of elasticity ranged from 292.98 to 507,91 MPa in, bending strength ranged from 15.76 to 9,23 MPa, tensile strength of nails ranged from 241.8 to 241,88 N, hardness ranged from 13.921 to 13,674 HB, compressive strength ranged from 43,78-44,232 Mpa. The physical properties of composite were as follows water absorption (2 hour immersion) ranged from 19.3% to20.2%, water absorption (24 hour immersion) ranged 20.7% to 20.3%, mechanical power (depth 15 mm) ranged from 1.69 to 1.698 KW, density ranged from 1.29 to 1.155 gr/cm 3 , and fracture surface showed a good interfacial bonding. c. The results of simulation generated the recommendations for a composite material using. The best recommendation orientation for a simple seat is a composite with 0 0 fiber orientation angle. Because the materials used less dimension of material many and lighter than the other angle orientation.
