    Comparative study of natural rubber and acrylonitrile rubber reinforced with aligned short aramid fiber
    (2017-12-01) Pitchapa Pittayavinai; Sombat Thanawan; Taweechai Amornsakchai; Mahidol University
    © 2017 The aims of this paper are three-fold. The first is to determine the reinforcement of high performance short aramid fiber in two representative rubber matrices, namely natural rubber and acrylonitrile rubber. The second is to ascertain... the effect of rubber polarity on the reinforcement. The third is to establish a pattern of reinforcement for use with less studied fibers. The rubbers were reinforced either with only aramid fiber or with a hybrid of aramid fiber and carbon black. The fiber

    Effect of mastication time on the low strain properties of short pineapple leaf fiber reinforced natural rubber composites
    (2017-02-01) Kanokwan Yantaboot; Taweechai Amornsakchai; Mahidol University
    © 2016 Elsevier Ltd Pineapple leaf fiber (PALF), used as a reinforcing agent, does not have good adhesion to natural rubber (NR) due to the difference in their polarities. As a result, the degree of reinforcement of NR imparted by PALF remains low... compared to that in a polar rubber like acrylonitrile butadiene (NBR). One of the factors that determines the adhesion between the rubber and the reinforcement is the rubber molecular weight. Thus, the aim of this paper is to demonstrate that the stress

    VULCANIZATION FOR REINFORCEMENT OF RUBBER
    (2022-04-01) Ikeda Y.; Miyaji K.; Ohashi T.; Nakajima T.; Junkong P.; Mahidol University
    Sulfur cross-linking reagents play critical roles not only in cross-linking rubber chains but also in controlling network morphology for reinforcement of rubber. Zinc oxide (ZnO) is clearly discovered as the main component for both roles. Especially..., the importance of network inhomogeneity, which is significantly governed by the dispersion of ZnO particles, is emphasized for reinforcing rubber materials. Specifically, the formation of network domains and their continuous structures is discussed by combining

    Synergistic effect of cuttlebone particles and non-rubber components on reinforcing ability of natural rubber and synthetic isoprene rubber composites
    (2022-06-20) Chongcharoenchaikul T.; Miyaji K.; Junkong P.; Poompradub S.; Ikeda Y.; Mahidol University
    The comparison of the reinforcing ability of cuttlebone (CTBO) particles in natural and synthetic isoprene rubber (NR and IR, respectively) composites were investigated. The CTBO particles could reinforce in both NR and IR composites. However..., the improvement of tensile properties in CTBO-filled NR composites was higher than that of IR composites due to the presence of non-rubber components in NR. The non-rubber components promoted the strong interfacial adhesions with filler and rubbery matrix

    An anomalous reinforcement of ordinarily weak synthetic rubber
    (2015-08-27) Kontapond Prukkaewkanjana; Taweechai Amornsakchai; Mahidol University
    © 2015, Springer Science+Business Media Dordrecht. Synthetic rubbers were invented during the World War II due to the shortage of natural rubber in Europe and America. They are superior to natural rubber in various aspects except in strength.... Despite a great amount of research work, they still cannot be stretched to strains predicted by theory. Nevertheless they can be strengthened by reinforcement, usually with carbon black or silica. However such reinforcement comes with the sacrifice

    Realising the Potential of Pineapple Leaf Fiber as Green and High-performance Reinforcement for Natural Rubber Composite with Liquid Functionalized Rubber
    (2021-09-01) Budsaraporn Surajarusarn; Satit Thaiwattananon; Sombat Thanawan; Karine Mougin; Taweechai Amornsakchai; Mahidol University; CNRS Centre National de la Recherche Scientifique
    In this work, it is attempted to demonstrate the potential of natural fiber namely pineapple leaf fiber (PALF) as high performance green reinforcement for natural rubber. Liquid carboxylated isoprene rubber was used as an adhesion promoter (AP...) to improve the adhesion between the fiber and the rubber matrix. Three types of fibers, i.e. untreated, sodium hydroxided treated and silane treated, were used. PALF and carbon black were combined to form hybrid reinforcement. Fiber content and carbon black

    Natural reinforcement in Hevea rubber: Functional roles of non-rubber components from biosynthesis to performance

    in synthetic rubbers. These properties are largely attributed to non-rubber components (NRCs)—such as proteins, phospholipids, lipids, carbohydrates, and inorganic ions—which serve as intrinsic stabilizers, reinforcing agents, and vulcanization accelerators.... Furthermore, NRCs affect interactions between rubber matrices and reinforcing fillers such as carbon black (CB) and silica, thereby influencing reinforcement efficiency and compound performance. By integrating insights from molecular structures, colloidal

    Pineapple leaf fiber: A high potential reinforcement for green rubber and plastic composites
    (2017-01-01) Taweechai Amornsakchai; Mahidol University
    applications. Recently our research group has developed a method to extract short and fine PALF from leaf waste. PALF was used to reinforce different types of rubbers to produce rubber composites with very high stretching stress at low elongations. Rubber... reinforcements using hybrid or combination of PALF/silica and PALF/carbon black were also studied and very promising results were obtained. For plastic reinforcement, both PALF and non-fibrous material (NFM) were tested on polypropylene in order to fully utilize
