Composite materials play a vital role in many industrial applications. Researchers are working on fabrication of new composite materials worldwide to enhance the applicability of these materials. The present study aimed to investigate the effect of Nano clay loading as filler on the mechanical properties of the bamboo fiber yarn reinforced polyester composite. Five different types of composite specimen were prepared with Nano clay loadings of 0 to 4 % weight fraction using hand lay-up technique. It was observed that the composite sheet with 1 wt % nano clay content exhibited the optimized tensile and flexural strength. However the mechanical properties tend to decrease with addition of nano clay content from 2 to 4 wt %. In spite of that the values of mechanical properties with 2 and 3 wt % nano clay content is higher than 0 wt % nano clay content.

Rapid Prototyping System

Purpose Stereolithography is a well-established technique for producing complex part for rapid prototyping purpose by using UV or laser as a source for curing process. This technique has been implemented in a lot of industrial sectors. However, the parts fabricated by this technique exhibit low mechanical and thermal properties hindering a fast-growing application. The purpose of this paper is to propose a new method of digital light rapid prototyping (DLRP) system and investigate the effect of the addition of bamboo fiber with surface modification on improvement of mechanical properties of urethane diacrylate/bamboo composite. Design/methodology/approach Test specimens were fabricated using aliphatic urethane diacrylate photopolymer as matrix material and bamboo fiber as reinforce material. Adhesion between matrix and reinforce materials is a big issue in compositing, especially when handling bamboo as hydrophilic material and urethane diacrylate as hydrophobic material. To overcome this problem, two surface modifications of bamboo fiber, alkali treatment and silane treatment, were implemented. Findings As a result, bamboo fiber can increase mechanical properties of urethane diacrylate photopolymer fabricated by rapid prototyping system. Originality/value In this paper, the authors investigate the effect of the addition of bamboo powder with surface modification on mechanical properties. Test specimens were fabricated using aliphatic urethane diacrylate photopolymer as matrix material and bamboo powder as reinforce material.

Epoxy resins have been presenting a lot of scientific and technical interests and organic modified epoxy resins have recently receiving a great deal of attention. For obtaining the composite materials with good mechanical proprieties, a large variety of organic modification agents were used. For this study gluten and gelatin had been used as modifying agents thinking that their dispersion inside the polymer could increase the polymer biocompatibility. Equal amounts of the proteins were milled together and the obtained compound was used to form 1 to 5% weight ratios organic agents modified epoxy materials. To highlight the effect of these proteins in epoxy matrix mechanical tests as three-point bending and compression were performed.

Biomass Components

With the depletion of petroleum energy, the possibility of prices of petroleum-based materials increasing, and increased environmental awareness, biodegradable materials as a kind of green alternative have attracted more and more research attention. In this context, poly (lactic acid) has shown a unique combination of properties such as nontoxicity, biodegradability, biocompatibility, and good workability. However, examples of its known drawbacks include poor tensile strength, low elongation at break, poor thermal properties, and low crystallization rate. Lignocellulosic materials such as lignin and cellulose have excellent biodegradability and mechanical properties. Compounding such biomass components with poly (lactic acid) is expected to prepare green composite materials with improved properties of poly (lactic acid). This paper is aimed at summarizing the research progress of modification of poly (lactic acid) with lignin and cellulose made in in recent years, with emphasis on effects of lignin and cellulose on mechanical properties, thermal stability and crystallinity on poly (lactic acid) composite materials. Development of poly (lactic acid) composite materials in this respect is forecasted.
