Nanocomposites strength

The performed numerical analysis showed that gallery failure is the direct cause of strength reduction of the intercalated nanocomposite. The nanocomposite strength is found to decrease with increasing clay volume fraction. This trend is in qualitative agreement with available experimental results. [Pg.31]

The data provided by Toyota Research Group of Japan on polyamide-MMT nanocomposites indicate tensile strength improvements of approximately 40%-50% at 23°C and modulus improvement of about 70% at the same temperature. Heat distortion temperature has been shown to increase from 65°C for the unmodified polyamide to 152°C for the nanoclay-modified material, all the above having been achieved with just a 5% loading of MMT clay. Similar mechanical property improvements were presented for polymethyl methacrylate-clay hybrids [27]. [Pg.34]

This is the most widely used naturally occurring rubber. The literature search shows that many research groups have prepared nanocomposites based on this rubber [29-32]. Varghese and Karger-Kocsis have prepared natural rubber (NR)-based nanocomposites by melt-intercalation method, which is very useful for practical application. In their study, they have found increase in stiffness, elongation, mechanical strength, and storage modulus. Various minerals like MMT, bentonite, and hectorite have been used. [Pg.34]

Patel et al. [70] in a recent publication have explored the adhesive action of the mbber-siUca hybrid nanocomposites on different substrates. The rubber-silica hybrid nanocomposites are synthesized through in situ silica formation from TEOS in strong acidic pH within acryhc copolymer (EA-BA) and terpolymer (EA-BA-AA) matrices. The transparent nanocomposites have been apphed in between the aluminum (Al), wood (W), and biaxially oriented polypropylene (PP) sheets separately and have been tested for peel strength, lap shear strength, and static holding power of the adhesive joints. [Pg.83]

The copolymer-silica adhesives also follow a similar trend but fail much earlier than the terpolymer-based adhesives. This is because of two factors (1) the increase in the inherent strength of the adhesive due to more favorable terpolymer rubber-silica interaction and (2) chemisorption in much higher magnitude between the polar substrates and the nanocomposites. [Pg.83]

This fantastic property of mechanical strength allows these structures to be used as possible reinforcing materials. Just like current carbon hber technology, this nanotube reinforcement would allow very strong and light materials to be produced. These properties of CNTs attracted the attention of scientists all over the world because of their high capability for absorbing the load which is applied to nanocomposites [23-25]. [Pg.92]

Nylon-6-clay nanocomposites were also prepared by melt intercalation process [49]. Mechanical and thermal testing revealed that the properties of Nylon-6-clay nanocomposites are superior to Nylon. The tensile strength, flexural strength, and notched Izod impact strength are similar for both melt intercalation and in sim polymerization methods. However, the heat distortion temperature is low (112°C) for melt intercalated Nylon-6-nanocomposite, compared to 152°C for nanocomposite prepared via in situ polymerization [33]. [Pg.667]

Silanol-terminated PDMS and hexadecyltrimethylammonium-exchanged clay were used to prepare PDMS-clay nanocomposites via melt intercalation [90]. The melt intercalation nanocomposites did not achieve as high a reinforcement as the aerosilica silicone hybrid, but the nanocomposite formed from solution had a nearly identical reinforcing effect on tensile strength as the aerosilica composite. [Pg.667]

Liu et al., 2005). Chemical functionalization can improve strength, thermal, electronical properties of polymer/CNT composites and will play a key role in future development and applications of CNT-based nanocomposites. [Pg.204]
