چکیده :

High strength and high impact resistant polymeric nanocomposites are one of the most potent materials for numerous applications such as aerospace, automotive, marine, military, industry, and sporting goods. Ultra high molecular weight polyethylene (UHMWPE) fiber can be considered as one of the potent fibers due to its unique characteristics such as high tenacity and modulus. The use of carbon nanotube (CNT) as a filler with high specific surface area that maximizes the fractional interface area is particularly desirable in the design of composites. In this research, ultra high molecular weight polyethylene (UHMWPE) fiber/carbon nanotubes composite was fabricated with high temperature-high pressure sintering/compaction method. The influence of the temperature of fabrication method on the impact resistant of the composite was investigated by drop weight test. The results showed that in pressure 4 MPa and in 20 min time, impact energy absorption is up to the highest value when the sintering/compaction temperature is about 120. The study results would be valuable for the proper preparation of high impact resistant composites.
