1. Mechanical Properties Analysis of Al2024 alloy Submitted to Different Aging Time and different Cold Plastic Deformation degree
Brazilian aeronautical industries report that, due to the high mechanical properties presented commercially, AA2024-T351 alloy presents fissures and non-homogeneous deformations during the mechanical processing. This work proposes a manufacturing process capable of increasing the ductility of the material to withstand tensions during processing and a subsequ

2. Selecting chemicals for separation of ABS and HIPS in WEEE by froth flotation
Abstract The feasibility of using common chemicals to separate plastics from waste electrical and electronic equipment (WEEE) by froth flotation is investigated. Plastic waste is one of the WEEE polluters and a separation is necessary to recycle it. The most common plastics in electronic industries are acrylonitrile-butadiene-styrene (ABS) and high impact po

3. Preparation and characterization of composites from plastic waste and sugar cane fiber
Abstract This study presents the preparation and characterization of composite materials using Plastic Waste from Hydrapulper (PWH) from paper industries extruded with sugar cane fiber residues from ethanol industries. The factorial design showed that composite material with 40% of sugar cane fiber, pressed with 5 ton was the optimized condition. The main f

4. The Analysis of the Cold Flat Rolling Process by Salf Program
SALF program is a Brazilian program developed to simulate the cold flat rolling process by the finite element method. The program uses the implicit and rigid-plastic approaches to perform numerical analyses. This article presents the cold flat rolling simulations performed by SALF, where the variables of rolling force, effective strain rate, and effective st

5. Cardanol-based thermoset plastic reinforced by sponge gourd fibers (Luffa cylindrica)
Abstract A growing global trend for maximum use of natural resources through new processes and products has enhanced studies and exploration of renewable natural materials. In this study, cardanol, a component of the cashew nut shell liquid (CNSL), was used as a building block for the development of a thermosetting matrix, which was reinforced by raw and mod

6. An experimental investigation of static load capacity of AL-GFRP adhesively bonded single lap and double butt lap joints
AbstractThis paper is focused on experimental evaluation and comparison of progressive damage behaviors in adhesively bonded single lap and double butt lap joints between aluminum and glass fiber reinforced plastic (GFRP). The effect of joint design and dissimilarity of adherents on damage evolution of adhesive bonding under tensile quasi static loading is a
