High-Tech Textiles
1. Smart flame-resistant textile
1) 배경
IED(Improvised Explosive Deviced:급조폭발물)로 인한 사상자발생으로
화염방지의 필요성을 절감하였다.
2) Nomex®
듀퐁사에서 1960년대 초반에 개발한 Aromatic polyamid(aramid) fiber로 1967년부터 상업적으로 생산되기 시작. 지금은 화염방지 소재에 있어 하나의 명
instrument composition
-Electric furnace
Temperature range:
25°C~1500°C
Heat speed :
Maximum 200°C/min
*Separate Electric furnace and other system like Electronic scale
-Because Electric furnace temperature is very high
so we need to protect other system.

composite Vf = Volume fraction of fiber
σf : Strength of fiber Vf +Vm =1
σm : Strength of matrix MMC : Boron fiber/Al (2024) alloy
300M :
Raw material of the MMC
- Boron cost : 5000$/Kg
- Al (2024) alloy : 6000 won/Kg
300M(AMS 6417) : 168$
Produced in single-filament reactors by CVD, boron fiber exhibits a unique combination of High Strength High Modulus and Lar
high-quality ingredients, like DiGiorno Ultimate pizza, Cote d’Or chocolate, Oscar Mayer center cut bacon and Tassimo hot beverage system.
- Market Performance and Financial Performance
With revenues of $37billion, Kraft Foods Inc. is one of the world’s largest food and beverage companies. Moreover, its products are present in more than 99% of U.S. households. Kraft markets many of t
Reinforced Concrete) structure is as following.
1) high economic performance
2) because resources expense is inexpensive than steel-frame structure) corrosion resistance that prevent corrosion of interior reinforcing rod because is alkalinity is security
3) have excellent modeling.
4) ability that have high hardness and stand in shock of pedestrian or machine operation etc. is big.
