Tensile Damage Assessment on Carbon Fiber Reinforced Laminate For 45 ° and 90 ° Layout Orientation

Damage assessment is an important criteria to determine properties and characteristic for any material. The diversity of fiber orientation and production method are among the source of uncertainty in the behavior of carbon fiber composite product. The effort to study the effect of carbon fiber layout orientation on layout orientation of 45 ° and 90 ° to the tensional force was investigated in this study. The specimen was fabricated using single vacuum bagging method from the carbon fiber reinforced prepreg to produce carbon fiber reinforcement laminate (CFRL). The damage assessment was executed using tensile testing by following the ASTM D3039 with sample dimension of (320 × 250 × 2.5) mm. Morphology assessment using scanning electron microscope (SEM) was included to investigate closely the fiber and matrix fracture after breakage. Tensile results showed significant different behavior on both orientations where 45 ° layout orientation exhibit ductile behavior meanwhile 90 ° layout orientation tended to have clear brittle behavior.
