New Polymer Science and Technology Findings from Rzeszow University of Technology Reported (Photocured Unsaturated Polyester Composites Reinforced With Glass and Natural Fiber Used In the Pipeline Renovation)

2024 NOV 19 (NewsRx) -- By a News Reporter-Staff News Editor at NewsRx Science Daily -- New research on Science - Polymer Science and Technology

Article Description

The vacuum bag method was used to obtain photocurable polyester resin composites, in which part of the glass fiber (3 wt%) in the glass mat was replaced with natural fiber (sisal, hemp and kenaf). The physicochemical properties of natural fibers (wetting angle, UV/VIS radiation transmittance) were determined. The influence of the hybrid filler on the structure (SEM) and mechanical properties of the composites was investigated in terms of their application in pipeline systems. The introduction of natural fiber reduced the stiffness and tensile strength of the composites. Due to the smallest wetting angle for polar and nonpolar liquids and the total UV/VIS radiation transmittance (425 nm) of sisal fiber, the best processing and mechanical properties were obtained for laminates reinforced with this fiber (tensile strength 257 MPa, flexural modulus 20.5 GPa).
