Abstract

Composite is a material that is formed from a combination of 2 or more materials. The orientation of the inclination angle of the webbing on the composite affects the tensile strength value. This research was conducted to determine the effect of variations in the angle of inclination of the webbing and the phenomenon of delamination on the value of tensile strength. The process of making fiberglass woven fiber composites and a mixture of resin and catalyst uses the vacuum bagging method. The variations used in this study are the angle of inclination of the webbing 0°, 15°, 30° and 45°. Tensile test specimens using the ASTM D638 standard. The specimens that have been cut will then be perforated with a diameter of 4 mm using a milling machine. Tensile testing was carried out using a Universal Testing Machine. The highest tensile strength value is at an angle of 0° with a value of 189.30 MPa and the lowest tensile strength is at an angle of 45° with a value of 34.25 MPa and for the value of the delamination factor has little effect on the value of tensile strength.

Abstract

Curing is a method used to enhance the performance of composite materials by heating them in an electric oven for a specific duration and at a controlled temperature. This study aims to examine the effect of curing time variations on the failure analysis of carbon fiber sandwich composites with a PVC foam core under bending tests. The materials used in this research include polyester resin, 240 gsm carbon twill fiber, and a 5 mm thick PVC foam core. The manufacturing method applied was vacuum bagging, followed by a curing process with time variations of 30 minutes, 60 minutes, 90 minutes, and 120 minutes at a constant holding temperature of 80°C. Bending tests were carried out according to ASTM C393 standards. The highest bending strength of the sandwich composite was achieved with a curing time of 120 minutes, reaching 45.55 MPa, while the lowest strength was observed in the specimen without curing, at 25.76 MPa. The failures observed after bending tests included core failures such as core crush, indentation, and delamination, as well as skin failures like micro buckling.
