Special Issue Information

Dear Colleagues,

The introduction of biomass in composite production has been extensively studied and adopted by the industry. This can be attributed to the wide availability of biomass, the lower cost of biomass, and its proven technical feasibility and enhanced product quality. Recently, focus has been placed on the development of functional biomass-based composites, wherein the specifically treated biomass is not only able to reinforce the composite, but could also deliver a specific functionality to the product made thereof. This integrated feature adds value to the conventional biomass-based composites.

Thus, this Special Issue focuses on reports of biomass treatments and their incorporation and performance in composites to deliver specific applications. The main scope covers, but can be expanded beyond, the following core areas:

  • Functional biomass-based composites;
  • Stress transfer mechanism and interfacial properties for biomass-based composites;
  • Synthesis and application of biomass-based composites;
  • Treatment/modification of biomass material for the preparation of composites;
  • Characteristics of biomass-based composites related to their application.

Bio-based resins, obtained from renewable raw materials, are a more sustainable alternative to oil-based resins for fiber-reinforced polymer (FRP) composites. The incorporation of lignin in those resins has the potential to enhance their performance. This paper presents results of an experimental study about the effects of Lignoboost lignin incorporation on a partially bio-based vinyl ester (VE) resin. Two resins were prepared—without (reference) and with lignin addition (4% by weight) to its main chain—and their chemical, thermophysical, and mechanical properties were compared using Fourier transform infrared (FTIR) spectroscopy, gel permeation chromatography (GPC), dynamic mechanical analysis (DMA), thermogravimetric analysis (TGA), and tensile and shear tests. Results suggest that the addition of lignin to the base resin resulted in a copolymer of increased heterogeneity and higher molecular weight, incorporating stiff and complex aromatic structures in the polymer chain. While requiring high-temperature curing, the VE–lignin copolymer presented improvements of 27% in tensile strength, 4% in shear strength, and increased glass transition temperature by about 8 °C, thus confirming the potential of this natural biopolymer for FRP composite applications.
