Context:The quality of light curing units can profoundly influence mechanical properties dental composite materials. Aim: To compare effect Woodpecker RTA Mini-S and Elipar Deep Cure-L onmechanical (compressive strength, diametral tensile strength microhardness) Filtek Bulk-Fill. Methods Materials: A total 32 samples Bulk Fill were divided into 2 equal groups (n=16). 12 in each group fabricated...

In order to improve the ablation resistance of C/C composites, an AlSiB alloy (mass ratio Al/Si/B = 2:4:1) was used as a dissipative agent fill pores composites matrix by reactive melt infiltration prepare AlSiB-C/C composites. The microstructure evolution and behavior obtained under oxy-acetylene flame were investigated SEM after ablating for 25 s, 50 100 s 150 s. At beginning process, thermal...

BACKGROUND This study compared the storage modulus (E'), the loss modulus (E'') and the loss tangent (tan δ) of various flowable resin composites. MATERIAL AND METHODS Grandio Flow (GRF), GrandioSo Heavy Flow (GHF), Filtek Supreme XTE (XTE) and Filtek Bulk Fill (BUL) flowable resins and Clinpro Sealant (CLI) ultra-flowable pit and fissure sealant resin were used. 25 samples were tested using ...

In this paper, we model and compute flow-induced mechanical properties of nematic polymer nanocomposites, consisting of transversely isotropic rigid spheroids in an isotropic matrix. Our goal is to fill a gap in the theoretical literature between random and perfectly aligned spheroidal composites (Odegard et al. in Compos. Sci. Technol. 63, 1671–1687, 2003; Gusev et al. in Adv. Eng. Mater. 4(12...
