Abstract

Abstract: This study presents a novel approach to improve the precision of tubular bending processes. By integrating a torch burner into the conventional manual bending tool, a method was developed to soften the workpiece prior to bending, effectively reducing defects attributed to forced bending. The research includes manual calculations and SolidWorks simulations for comparative analysis. The proposed tool design, utilizing a 40 mm x 40 mm x 700 mm L-profile iron frame with ASTM A36 material, demonstrated successful bending of pipes with ∅ outside 25 mm and ∅ inside 20 mm, achieving a seamless 180° bend from the initial 0° position. The results highlight enhanced bending accuracy and underline the potential of torch-assisted bending for broader applications in fabrication and manufacturing processes. Highlight: nnovative Integration: Integration of a torch burner with a manual bending tool for enhanced precision in tubular bending processes. Defect Reduction: Softening the workpiece before bending reduces defects associated with forced bending, ensuring higher quality outcomes. Comprehensive Analysis: The study employs both manual calculations and SolidWorks simulations for a thorough comparative analysis, validating the proposed approach's efficacy.

Abstract

Alkali treatment of natural fibers has a role in removing hemicellulose and lignin layers. This layer prevents the matrix from bonding with the natural fiber cellulose structure. The use of an inappropriate type of alkali will reduce its effectiveness and can even damage the cellulose layer. This study compared the effectiveness of alkaline NaOH, CaOH and KOH in removing lignin and hemicellulose and their ability to maintain cellulose content. The use of the immersion method in alkaline solutions is well controlled. The FTIR characterization test was used to detect functional group changes, the TGV test to detect heat resistance ability, the XRD test to detect structural changes in crystalline and amorphous properties of sansevieria natural fibers. Furthermore, the tensile test to determine the effect of alkaline treatment on changes in mechanical strength Tensile strength. From the test results it was found that the alkaline NaOH gave the best characteristics by detecting the presence of cellulose, tensile strength and the nature of the crystalline atomic structure. Highlights: Effectiveness of Alkali Types: Comparison of NaOH, CaOH, and KOH effectiveness in removing lignin and hemicellulose while preserving cellulose content. Characterization Techniques: FTIR, TGA, and XRD tests used for functional group changes, heat resistance, and structural properties evaluation. NaOH Superiority: Alkaline NaOH treatment demonstrated best results in maintaining cellulose, enhancing tensile strength, and influencing atomic structure. Keywords: Alkali treatment, Natural fibers, Lignin removal, Cellulose preservation, Tensile strength.
