Serat Bambu Petung (Dendrocalamus asper) Teralkalisasi sebagai Penguat Komposit Polimer (original) (raw)

The alkalized of petung bamboo fiber (Dendrocalamus asper) as reinforcement of polymer compositePetung bamboo (Dendrocalamus asper) has good fiber characteristic and it has potential to substitute glass fiber as reinforcement in polymeric composite. However, like other natural based materials, bamboo fiber has a high variability in mechanical properties and inherently hygroscopic characteristic. Therefore it is required to optimize the petung bamboo qualities. The fiber optimization was carried out by alkalization process using NaOH solution with varying concentration of 0, 3, 5, and 10% v/v. Bamboo fiber processed in chemomechanical was used in this investigation. Characterization of density, mechanical and chemicals was conducted by pycnometry method, tensile strength testing, Fourier Transform Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The data variability was analyzed by Weibull distribution. Result indicates that the optimum condition of alkalization process of...
