In this study, the effects of incorporating recycled photopolymer-plate residues from a packaging flexography process into polyester-glass fiber composites were examined. Ternary with an unsaturated polyester matrix elastomer particles evaluated using two types glass fibers: in forms fabric bidirectional fibers and blanket multidirectional fibers. The prepared by hand lay-up lamination differen...

Four new unsaturated aliphatic acid amides, named zanthoamides A-D (1-4), and eight known ones-tetrahydrobungeanool (5), ZP-amide A (6), ZP-amide B (7), ZP-amide C (8), ZP-amide D (9), ZP-amide E (10), bugeanumamide A (11), and (2E,7E,9E)-N-(2-hydroxy-2-methylpropyl)-6,11-dioxo-2,7,9-dodecatrienamide (12)-were isolated from the pericarps of Zanthoxylum bungeanum. The structures of these compoun...

Polyester based particle reinforced composites were developed using varying weight fractions (ranging from 0 to 30 wt%, at 5 wt% interval) of microcrystalline wood charcoal powder (75µm). Quantitative, qualitative and functional characterization (WC) particles polyester matrix was carried out successfully energy dispersive x-ray spectrophotometer (EDXRF), Fourier transform infrared spectrometer...

Polymer concrete (PC) is a composite construction material that boasts several advantages, such as lightness, low water permeability, high resistance to corrosive environments, and chemical degradation. Consequently, it has recently attracted interest an alternative the traditional ones for civil applications. In this study, unsaturated polyester resin was considered matrix phase of PC. Aimed p...
