추진기관용 노즐에 사용하는 대표적인 소재로는 흑연소재와 탄소/탄소 복합재료를 들 수 있다. 흑연 소재는 열충격 저항성이 취약하여 사용 중 파손의 발생가능성이 높아 현재는 열축격 저항성이 우수한 탄소/탄소 복합재료를 주로 사용하고 있다. 본 연구를 통하여 수입에 의존하였던 Quasi-3D 구조의 니들펀치(Needle Punch) 프리폼을 국산화 개발하였다. 본 연구에서는 니들펀치 프리폼의 제조 공정 및 밀도화 공정을 다루고자 한다.

As devices have evolved, traditional flip chip bonding and recently commercialized thermocompression bonding techniques have been limited. Laser-assisted bonding is attracting attention as a technology that satisfies both the requirements of mass production and the yield enhancement of advanced packaging interconnections, which are weak points of these bonding technologies. The laser-assisted bonding technique can be applied not only to a two-dimensional bonding but also to a three-dimensional stacked structure, and can be applied to various types of device bonding such as electronic devices; display devices, e.g., LEDs; and sensors.

This paper reviews the potentials of a rotary chemical vapor deposition (RCVD) process for nanomaterial synthesis and coating on powder-based materials. The rotary reactor offers a significant improvement over traditional CVD methods having horizontal and fixed reaction chambers. The RCVD system yields enhanced productivity and surface coating uniformity of nanoparticles applied in various purposes, such as efficient heat dissipation, surface hardness enhancement, and enhanced energy storage performances. The effectiveness of the RCVD system would open up new possibilities in various applications because uniform coating on powder-based materials with massive productivity is inevitable to develop multi-functional materials with high reliability.
