• Microalgae ultrasound pre-treatment induces strengthening of biocomposites. 20% wt. polycaprolactone reinforced residual Desmodesmus materials. Proteins thermal degradation reduced deformability in Tetradesmus Ultrasound and protein extraction sp. obliquus biomass induced microalgae/polycaprolactone (PCL) biocomposites with higher viscoelastic mechanical properties as injection mould temperat...

A new class of biocomposites based on oil palm empty fruit bunch fiber and poly(butylene adipate-co-terephthalate) (PBAT), which is a biodegradable aliphatic aromatic co-polyester, were prepared using melt blending technique. The composites were prepared at various fiber contents of 10, 20, 30, 40 and 50 wt% and characterized. Chemical treatment of oil palm empty fruit bunch (EFB) fiber was suc...

Global environmental concerns, as well the rapid depletion of non-renewable fossil fuel-based resources, have prompted research into development sustainable, environmentally friendly, and biodegradable materials for use in a variety high-end applications. To mitigate setbacks caused by nonbiodegradable materials, biocomposites with improved mechanical performance is gradually gaining momentum. ...

The morphological and thermal properties of composites containing a bioplastic blend micro/nano-sized biochar from pyrolyzed jatropha seeds microwave were investigated using scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, differential calorimetry. biocomposite samples exhibited brittle structure with slightly ductile chip-like appearance. spect...

This research was carried out to figure the effect of chemical treatments hazelnut shell powders (HSPs) on elastic properties, ultrasonic wave velocities, and damping properties bio-based epoxy resin (BER) biocomposites. Natural shells (HSs) were chemically treated using sodium hydroxide (NaOH), acetic anhydride (AA). Then, HSs that with NaOH AA, not subjected treatment ground obtain HSPs. The ...

The swelling of natural fibers is often a drawback when considering structural applications biocomposites. However, this mechanism represents the key towards development Hygromorph BioComposites (HBC). This investigation aims to understand hydroexpansion 3D-printed continuous flax-fiber reinforced biocomposites and effect matrix stiffness. Four flax fiber-based were selected with wide range Wat...

In this work, we report the effect of biopolymers (starch and gelatin) on in vitro biocompatibility property of nano hydroxyapatite (nHAp) composites. Cell culture and MTT assays were performed for in vitro biocompatibility. They show that nHAp can affect the proliferation of cells and the nHAp-starch and nHAP-gelatin biocomposites have no negative effect on the cell morphology, viability and p...

Due to significant environmental advantages, biocomposites have recently received increasing attention. In the present research, strength of hat-shaped coir fiber biocomposites tubes reinforced with nano powder was evaluated experimentally under 3-point bending tests. The tubes were manufactured using hand lay-up technique and based on Taguchi design of experiment. The effects of different para...

Abstract Biocomposites of poly(lactic acid) (PLA) and pectin, which are low-cost organic materials, were prepared using an internal mixing machine in various pectin contents, i.e., 2, 4, 6 8% w/w. When was added as a nucleating agent, the mechanical properties biocomposites, such tensile impact testing, considerably improved, particularly following annealing process. In addition, PLA–pectin ann...
