  1. A Review: Natural Fiber Composites Selection in View of Mechanical, Light Weight, and Economic Properties

    Furqan Ahmad, Heung Soap Choi and Myung Kyun Park

    Article first published online: 2 SEP 2014 | DOI: 10.1002/mame.201400089

    Due to lightweight, low-cost, and reasonable strength natural fiber are replacing the synthetic fibers and because of these properties their applications in automobile industries were increased. Comparisons of material indices were made to investigate the possibility to use natural fiber composites instead of some conventional and non-conventional materials for beam and panel structures.

  2. Development of Proteinacious Plywood Adhesive and Optimization of Its Lap Shear Strength

    Tizazu H. Mekonnen, Paolo G. Mussone, Phillip Choi and David C. Bressler

    Article first published online: 2 SEP 2014 | DOI: 10.1002/mame.201400199

    Protein hydrolyzates were successfully modified into a plywood adhesive that met the ASTM D4690 requirement of both dry and soak strength for urea formaldehyde type of adhesive. Optimization of the formulation parameters including hydrolysis temperature, concentration of hydrolyzed protein and crosslinking resin, and mole ratio of the resin formulation were designed and analyzed using the Taguchi experimental approach.

  3. Reversibly Dispersible/Collectable Metal-Organic Frameworks Prepared by Grafting Thermally Responsive and Switchable Polymers

    Heyang Liu, He Zhu and Shiping Zhu

    Article first published online: 1 SEP 2014 | DOI: 10.1002/mame.201400251

    A reversibly dispersible/collectable metal-organic framework (MOF) system is presented. This system is based on the modification of MOF by grafting thermally switchable polymers. The resulted MOF materials, without losing their original framework, can be readily dispersed in water at room temperature and be re-collected when heated. The dispersion/collection process is reversible.

  4. Poly(vinyl alcohol) Cryogel Formation Using Biocompatible Ice Nucleating Agents

    To control the influence of supercooling on the preparation of poly(vinyl alcohol) (PVA) cryogel, various biocompatible ice nucleating agents, including, two fatty alcohols, and various amino acids are investigated for their ice nucleating efficiency in PVA aqueous solutions for the production of PVA cryogel at relatively higher freezing temperature.L-Aspartic acid is found to be the most effective ice nucleating agent that could nucleate ice in concentrated PVA aqueous solution at ∼−5 °C.

  5. Strategies for High Quality Injection Moulding of Polymer Nanopillars

    Rasmus H. Pedersen, Qian Xu, John M. Stormonth-Darling and Nikolaj Gadegaard

    Article first published online: 27 AUG 2014 | DOI: 10.1002/mame.201400134

    We show tunable reproduction of polymer nanostructures by injection moulding. Using a novel fabrication method to produce a master with a gradient in pattern height we conduct detailed investigations of the injection moulding process of nanopillar structures. Material choice and moulding parameters lead to optimization and control of the final result.
