A new generation of entirely biodegradable and bioactive composites with polylactic acid (PLA) or poly-ε-caprolactone (PCL) as the matrix and bioplastic flax fibers as reinforcement were analyzed. Bioplastic fibers contain polyhydroxybutyrate and were obtained from transgenic flax. Biochemical analysis of fibers revealed presence of several antioxidative compounds of hydrophilic (phenolics) and...

Three different samples of soft magnetic material Proto-pasta, a composite iron and polylactic acid (PLA), were printed in the presence field then measured using vibrating sample magnetometer (VSM) to inspect effects printing has on samples’ properties. Multiple hysteresis measurements taken with respect angle for each various fields observe changes loss susceptibility. The Fe/PLA composites Ma...

Polylactic acid (PLA) is a biodegradable polymer that widely used in medical devices, drug delivery systems, fibers for packaging containers and textiles. However, given interactions between the materials contact with it affect its applications, important to study adsorption diffusion properties. The capacity of different polylactic particles regarding additives, e.g. essential oils (Thymus vul...

Abstract This study aims to produce composite nanofibers from polylactic acid (PLA) and silk fibroin (SF) with mechanical properties similar that of a native meniscus. SF is natural protein, well known for its good biocompatibility biodegradability but it has poor compared synthetic polymers. contains proteins which can promote cell adhesion proliferation required tissue engineering scaffold. P...

This study proposes a vibration suppression technique that uses piezoelectric material to restrict the dynamic amplitudes of cantilever beam. The finite element analysis (FEA) model is created and incorporated with Macro Fiber Composite (MFC8507-P2) in ANSYS framework. A comparative has been performed using three different types materials i.e., Polylactic acid (PLA), PLA Short Carbon Fibers (PL...

In this paper, a polylactic acid (PLA)/polybutylene carbonate (PBC)/chitosan (CS) composite membrane with different mass fractions of ciprofloxacin hydrochloride (CipHCl) drug was prepared through the electrostatic spinning technology. The morphology and chemical structure resultant CipHCl-PLA/PBC/CS fiber membranes were characterized scanning electron microscopy (SEM), Fourier transform infrar...

Antibiotic-impregnated beads are used in the dead bone space following debridement surgery to deliver local, high concentrations of antibiotics. Polymethylmethacrylate (PMMA), 2,000-molecular-weight (MW) polylactic acid (PLA), Poly(DL-lactide)-coglycolide (PL:CG; 90:10, 80:20, and 70:30), and the combination 2,000-MW PLA-70:20 PL:CG were individually mixed with clindamycin, tobramycin, or vanco...

In this study, the mechanical properties of 3D printed polylactic acid (PLA) samples produced with fused deposition modeling (FDM) technology five different infill patterns; trihexagon, triangle, line, gyroid, and grid, these patterns were compared for their properties. second part PLA specimens covered polyacrylonitrile (PAN) nanofibers synthesized by electrospinning method to enhance poor ten...

A bone defect resulting from open bone trauma may easily become infected; however, the administration of efficacious systemic antibiotics cannot be performed at safe levels. Previous studies have investigated anti-infective biomaterials that incorporate into bone and facilitate the direct application of high-concentration local antibiotics. In the present study, the effect of a novel porous com...
