Abstract Ceramic polymer materials have great future applications in the field of fireproof materials. However, ceramic polyolefins shortcomings such as few available inorganic fillers, high sintering temperature, and low flexural strength. Therefore, achieving rapid ethylene‐propylene‐diene rubber (EPDM) is an urgent problem that needs to be solved. Herein, we prepared EPDM using pyrophyllite ...
در سه دهه اخیر نانو کامپوزیت های پلیمری به واسطه رفتار و ویژگیهای فیزیکی و مکانیکی خاصشان مورد توجه محققین و دست اندرکاران صنایع مختلف قرار گرفتته شده اند. در این بین، نانو کامپوزیت های بر پایه خاک رس (مونت موریلونیت) از اهمیت بیشتری برخوردار شدند. مقاومت حرارتی بالا، مدول الاستیک زیاد، کاهش قابلیت آتش گیری، کاهش عبور پذیری گازها و جذب مایعات از جمله مهمترین ویژگی های این نوع نانوکامپوزیت ها می...
Otomotiv, beyaz eşya, savunma sanayi, uçak ve uzay sanayinde kullanılan bazı parçaların yüksek mukavemetli olmasının yanında aynı zamanda tok darbe dayanımlı olması da istenir. Bu çalışmada, ana matris malzeme olarak mühendislik polimerleri sınıfında yer alan poliamit 6 (PA6) polimeri kullanılmıştır. Katkısız PA6 ile ağırlık %5 oranında cam bilya (CB) katkılı (PA6-5CB), %15 elyaf (CE) takviyeli...
Ethylene propylene diene elastomers (EPDM) of various side chains and molecular weights were prepared as thin discs and the effects of electric field strength and temperature on the electromechanical properties were investigated. The electrical conductivity, the dielectric constant, the storage and loss moduli (G and G), the storage modulus response ( 1000V mm G ), and the storage modulus ...
Thermal benefits of different green roof samples were analyzed and compared. Experimental data from ongoing green roof projects was used in a theoretical analysis of air-conditioning energy savings with different green roof applications. Thermal data was collected from a typical non-reflective (EPDM) roof membrane and model green roof systems with three types of growth media (lava, arkalyte, an...
in this research work, the effects of natural fibers such as date palm fiber (df) and jute fiber (jf) on bending properties of polypropylene (pp)/ ethylene–propylene–diene–monomer (epdm) thermoplastic elastomers are investigated. for this purpose, the date palm and jute fibers at five levels of fiber weight fractions (0, 5, 10, 20 and 30 wt. %) are utilized during composite fabrication. maleic ...
