  • In this paper, the silicon rubber insulator for transmission line was experimented for 1,000 hours aging test in salt-fog condition. To evaluate and examine the aging properties of silicon rubber insulator for test, the leakage current of surface was measured. Also hydrophobicity and scanning electron microscopy were compared with initial and aged sample respectively Above results, we can confirm that the surface properties of silicon rubber insulator easily aged by salt-fog condition.

  • Cases involving bite marks have increased considerably since first reports of bite wound for the individual identification in Korea 1969. This is probably due to fact that investigating officers are now more aware of the value of bite mark evidence and are always alter to the possibility of sign of bite mark. Authors recently had an experience in the identification of a criminal by tracing marks made on silicon rubber impression from corp genital organ.

  • A piezoresistive pressure sensor using a silicone rubber membrane has been fabricated on the selectively diffused (100)-oriented n/n+/n silicon substrates by a unique silicon micromachining technique using porous silicon ething. The width, length and thickness of the beam were 120${\mu}m$, 600${\mu}m$ and 7${\mu}m$, respectively and the thickness of the silicone rubber membrane was 40${\mu}m$. By the fusion of silicon beam and silicone rubber membrane, the mechanical strength of the pressure sensor could be highly improved due to smaller shear stress. The effectiveness of the sensor was confirmed through an experiment and FEM simulation in which the pressure sensor was characterized.

  • Copper electroforming process has been applied to duplicate Koryo Tripitaka (Taejang'kyong), wooden printing block. Thin copper replica printing plates of 1 mm thickness was successfully manufactured from the printing face (54.5${\times}$25.5 cm) of wooden printing plate. Major processes are (1) silicon rubber replication of the master (2) silvering on silicon rubber (3) copper electroforming (4) separation of copper from the silicon mandrel (5) final coloring by brass plating and trimming. This process has various Potential applications in making thin metallic objects such as plaques, statues, bust and hollow metal objects for jewelry.

  • 실리콘 고무 멤브레인(membrane)에 실리콘 빔(beam)들이 삽입된 형태의 저차압센서를 개발하였다. 제작된 저차압센서는 실리콘 고무(silicone rubber)를 멤브레인으로 사용함으로써 열악한 환경에서도 다양한 응용분야에 적용 가능하도록 하였다. 실리론 고무 멤브레인을 사용한 압저항형 저차압센서는 선택적으로 도핑(doping)된 (100) n/n+/n 웨이퍼 상에 다공질 마이크로머시넝(micro-machining) 기술을 이용하여 제작되었다. 제조된 센서의 감도(sensitivity)는 $0.66{\mu}V/mmHg$이고, 0.1% 이하의 비선형성(non-linearity)을 보였다.

  • In this paper, the deformed shape, the contact forces and the load-displacement curves of the real hollow gasket made of silicon rubber are analyzed using a commercial finite element program MARC. In the numerical analysis, the silicon rubber is assumed to have the properties of the geometric and material nonlinearity and the incompressibility, and the hyperelastic constitutive relations of that material are represented by the generalized Mooney-Rivlin and Ogden models. The outer frictional contact between the hollow gasket and the groove of rigid container and the inner self-contact of the hollow gasket are taken into account in the course of numerical computation. Experiments are also performed to obtain the material data for numerical computation and to show the validity of the mechanical deformation of the hollow gasket, resulting in good agreements between them.

  • This paper, the hardness of the silicone rubber wire for 50, 60 degrees, 70 degrees High Temperature Vulcanizing (HTV) method using specimens were fabricated. In this paper, in order to investigate the dielectric properties of silicone rubber for wire specimens, the temperature range of $30^{\circ}C{\sim}170^{\circ}C$, the frequency range from 100Hz~4.5MHz report surveyed about the frequency and temperature dependent properties.
