TLDR
In this paper, two types of composite specimens were subjected to water absorption and outdoor weathering tests to assess their relative performance under environmental conditions, and the tensile strength, moduli, and ILSS of the weathered specimens were less than those of the unweathered ones.Abstract:
Jute–polyester composites were fabricated with untreated (control) and bleached slivers with 60% loading of fiber by weight and were designated as JPH(C) and JPH(B), respectively. Both types of composite specimens were subjected to water absorption and outdoor weathering tests to assess their relative performance under environmental conditions. While both composites showed low water absorption, JPH(B) showed lesser water absorption (8.48%) than did JPH(C) (12.25%). The mechanical properties like tensile and flexural strengths were measured for both the weathered and unweathered specimens and compared. The tensile strength of JPH(C) and JPH(B) decreased while the tensile modulus increased after weathering. The flexural strength, moduli, and ILSS of the weathered specimens were less than those of the unweathered ones. The nature of the fiber–matrix adhesion could be established from these results. The cause of every observation is explained. Thermal analyses (TG/DTG and DSC) of the composite specimens were also done. The overall thermal stability of JPH(C) was found to be better than that of JPH(B). © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 78: 1671–1679, 2000read more

Studies of acetylation, of jute using simplified procedure and its characterization
TL;DR: In this article, the authors used FTIR, DSC, TGA, and SEM studies to evaluate the extent of acetylation in dry and defatted jute fibers, and found that the maximum WPG was 18.0 for an acetic anhydride-pyridine system at 120°C for 4 h whereas using only acetic-anhydride wPG was 12.3 at the same reaction condition.
