“…The addition of flame retardant increased the modulus reduction value to 65%, while its highest magnitude obtained for mPET was 85%. As compared to the modulus reductions of srPP ranging between 71.5 and 87% [31][32][33] and those of natural fiber composites (between 65 and 75%) [23][24][25][26][27][28], the studied srrPET composites exhibited superior creep resistance.…”

“…One of the most commonly used extrapolation techniques is represented by the time-temperature superposition principle (TTSP), which utilizes real-time short-term creep responses obtained at elevated temperatures. Although TTSP was initially used only for pure polymers, numerous studies have utilized this principle to predict the long-term creep behavior of carbon-, glass-, and natural fiber-reinforced composites [24][25][26][27][28][29]. Due to the aging of the polypropylene matrix with time, TTSP successfully predicted the long-term creep response of polymer composites at ambient temperature, but was found to be unsuitable at higher temperatures [30].…”

Abstract. Creep deformation of polymers results from their inherent viscoelastic nature that changes polymer's shape with time. Creep response represents an important property of thermoplastic composites that affects their dimensional stability, especially in applications requiring the material ability to support relatively high loads for long periods. This work examines the creep behavior of self-reinforced recycled poly(ethylene terephthalate) (srrPET) composites, which were produced by film stacking from fabrics composed of double covered uncommingled yarns with recycled PET homopolymer filaments (serving as the reinforcements) and copolymerized PET (mPET) filaments (serving as the matrix). The short-term creep behavior of both srrPET and mPET was studied in the single cantilever mode below and above the glass transition temperature, and the obtained data were analyzed using the Findley's viscoelastic and Burgers four-element models. The long-term creep behavior of srrPET specimens with and without open circular holes was described using an Arrhenius-type time-temperature superposition principle.

“…Lignin in fiber is an advantage in biocomposite production. Lignin affects the compatibility between fibers and a polymer; it acts as a natural coupling agent due to its polar hydroxyl groups and non-polar hydrocarbon and benzene rings (Acha et al 2007). A validation experiment was carried out with the parameters as suggested by the model, and the comparison between the predicted and experimental values are summarized in Table 7.…”

“…Natural fiber-reinforced composites are emerging as replacements for those with synthetic fibers, as they are more environmentally friendly and more cost-effective than petroleum-based materials. Natural fibers offer several advantages to the composite industry, such as low density, high toughness, good specific strength properties, good thermal and insulation properties, low cost, non-abrasiveness on the processing equipment, biodegradability, and easy recycling (Acha et al 2007;BogoevaGaceva et al 2007;Raju et al 2008;Spoljaric et al 2009;Akil et al 2011). Therefore, the demands for natural fiber-reinforced composites have increased greatly over the past few years for various commercial applications (Akil et al 2011).…”

Optimization of Superheated Steam Treatment to Improve Surface Modification of Oil Palm Biomass Fiber

et al. 2016

Superheated steam (SHS) pretreatment is an effective method for hemicellulose removal from oil palm biomass (OPB) fiber, which leads to the surface modification of the fiber. However, the current SHS pretreatment is conducted at a high temperature and has a long retention time, which causes the removal of cellulose, which is an important component for biocomposite production. This study was conducted to optimize the SHS treatment temperature and retention time so that hemicellulose but not cellulose was removed. Three types of OPB fibers were used: oil palm mesocarp fiber (OPMF), oil palm empty fruit bunch (OPEFB), and oil palm frond (OPF). The chemical composition data was analyzed using a type of response surface methodology (RSM), i.e., central composite design (CCD). The optimal SHS treatment temperature and retention time were 265 °C/5 min, 280 °C/5 min, and 300 °C/9 min for OPMF, OPEFB, and OPF, respectively. The removal of hemicellulose at these temperatures was in the range of 60% to 70%, while the cellulose degradation was maintained below 5%. Statistical analysis showed that the optimal SHS treatment time can be shortened to 5 min to 9 min, which is 18 to 20 times shorter than previously reported methods.
