Sifat Kelenturan Komposit Hibrid Serat Gelas – Coremat Dengan Matrik Poliester 157 BQTN - EX.

Abstract

The making of hybrid composite has done for glass fiber – coremat by use of polyester 157 BQTN – ex as matric using press mold method. Flexural property test hybrid composit done for different composition layers are sample I: Sgwr – Fc – Fc – Sgwr, sample II: Fc - Sgwr – Sgwr – Fc, sample III: Sgcsm – Fc – Fc Sgcsm and sample IV Fc – Sgcsm – Sgcsm – Fc. Flexural properties test hybrid composite were done interlaminar shear strength test (ILSS), impact strength test (Is) and ultimate flexural strength test (UFS). From on the average result of interlaminar shear strength test obtained for smple I = 5, 87 MPa sample II = 6,66 MPa, sample III = 6,27 MPa and sample IV = 5,39 MPa. For Impact strength test obtained sample I = 64,22 kJ/ m2, sample II = 39,46 kJ/ m2, sample III= 42, 42 kJ/ m2, and sample IV = 68,20 kJ/ m2. And ultimate flexural strength test obtained sample I = 159,69 MPa, sampel II= 40,09 MPa, sample III = 186,13 MPa and sample IV 45, 02 MPa. By way of permute hybrid composite layer will then be change the value of mechanical properties.
