| dc.description.abstract | Composite materials are widely replacing previous traditional materials such as metals, woods and polymeric materials. The phenolic matrix can be modified by adding materials in order to improve the mechanical properties especially thermal resistance and abrasion. In this study, Carbon Nanotube(CNT) is used as a reinforcement particle to the phenolic resin for the purpose of improving ablative characteristics. Composite containing CNT shows advanced ablation characteristics in comparison with neat phenolic resin. CNT affects degree of crystallization of specimen with functioning as a crystalline nucleus in abrasion process. X-ray Diffraction(XRD) and SEM were carried out to confirm changing degree of crystallization of CNT-reinforced phenolic composites. | - |
