Composites of commercial unsaturated polyester resins containing nanofillers Nanobent. Part II. Nanocomposites with domestic nanofillers applied in Vacuum Casting technology

Abstract

Zbadano mo¿liwooeci wykorzystania nanokompozytów na osnowie nienasyconych ¿ywic poliestrowych (UP) (Polimal ® 103 i Polimal ® 109) z dodatkiem nanonape³niaczy Nanobent ® (ZR1 i ZR2) w technologii Vacuum Casting (VC). Oceniono reaktywnooeae (czas ¿elowania i maksymaln¹ temperaturê utwardzania) kompozycji odlewniczych oraz ich w³aoeciwooeci tiksotropowe, wp³ywaj¹ce w istotny sposób na przebieg procesu technologicznego wytwarzania prototypów kó³ zêbatych w matrycach silikonowych. Za pomoc¹ systemu optycznego ATOS II Triple Scan Blue Light firmy GOM oznaczono zale¿nooeae dok³adnooeci wymiarów geometrycznych otrzymanych modeli kó³ zêbatych od rodzaju nanonape³niacza i jego zawartooeci w kompozycie.

Mechanical enhancement of ripples and dimples in CaCO3/low-density unsaturated polyester resin composites

“…Figure 2(a) indicates that the temperature range of the maximum thermal decomposition rate of the NH 4 HCO 3 was from 70°C to 86°C, for three different particle sizes of CaCO 3 . The gel time of resin glue in the preparation of CaCO 3 /LDUPR should be controlled in the range of 25.0 min to 35.0 min [17][18][19], where, the gel time of resin glue lasted 4.0 min [20,21]. Figure 2(b) shows that the bleed time of NH 4 HCO 3 was 39.3-28.9 min in the temperature range of 72.0-80.0°C.…”

Vibration Analysis of a Low-Power Reduction Gear

“…The transverse vibrations of tooth gears with complex geometry and critical rotational speeds of rotating systems are further discussed [13]. Tooth gears made of nanocomposites are investigated in [14]. In [15], the problem for the transverse vibrations of circular plates with complex geometry is solved with the modified boundary element method.…”
