Abaca fibres, both uncoated (UF) and coated (CF) with Polyethylene (PE) and Vinyl Trimethoxy Silane (VTMS) copolymers (PEV), were included into High-Density Polypropylene (HDPP) composites for this investigation. Coated fibres CFa and CFb were created by coating the abaca fibre with a thin layer of hydrophobic polymer using copolymers comprising 3% VTMS (PEa) and 6% VTMS (PEb). Fourier Transform Infrared Spectroscopy (FTIR) investigation confirmed the coating procedure. HDPP and its amalgams with uncoated (HUF) and coated (HCF) were tested for their mechanical, water absorption, and biodegradation capabilities. When compared to an HDPP composite made with 6% UF, the addition of 6% CFb increased the Tensile Strength (TS) and Flexural Strength (FS) by 20.3–35.6%, correspondingly. According to the findings, CF and HCF composites absorbed far less water than UF and HUF variants. The compatibility between abaca fibres and HDPP polymeric matrix was also enhanced by treating the fibres with PEV. Degradation was also slower in the CF-containing composites compared to the UF-containing ones.

摘要

Abaca fibres, both uncoated (UF) and coated (CF) with Polyethylene (PE) and Vinyl Trimethoxy Silane (VTMS) copolymers (PEV), were included into High-Density Polypropylene (HDPP) composites for this investigation. Coated fibres CFa and CFb were created by coating the abaca fibre with a thin layer of hydrophobic polymer using copolymers comprising 3% VTMS (PEa) and 6% VTMS (PEb). Fourier Transform Infrared Spectroscopy (FTIR) investigation confirmed the coating procedure. HDPP and its amalgams with uncoated (HUF) and coated (HCF) were tested for their mechanical, water absorption, and biodegradation capabilities. When compared to an HDPP composite made with 6% UF, the addition of 6% CFb increased the Tensile Strength (TS) and Flexural Strength (FS) by 20.3–35.6%, correspondingly. According to the findings, CF and HCF composites absorbed far less water than UF and HUF variants. The compatibility between abaca fibres and HDPP polymeric matrix was also enhanced by treating the fibres with PEV. Degradation was also slower in the CF-containing composites compared to the UF-containing ones.
