“…Since the polymeric materials in the cellular membrane include hydroxyl and other oxygen-containing compounds that attract water via covalent bonds, the volume of lignin materials shifts as the quantity of water inside them increases. 50,51 Hemicelluloses do most of the work of absorbing moisture; however, visible cellulose, non-crystalline cellulose, lignin, and cellulose interface contribute significantly as well.…”

Natural fibers such as Banana fiber and sugarcane bagasse powder are used in the present study, which are abundantly available at low cost. Novel hybrid natural fiber reinforced composite specimen prepared by using the matrix material as epoxy (70%) with the addition of hardener and the reinforcement material (30%) used as NaOH chemical treated banana fiber with the addition of filler material as sugarcane bagasse powder to enhance the property. To prepare the composite material hand-lay process is used and manufactured three different combination of specimen by varying the composition ration of 10%, 15%, and 20% of reinforced material. The mechanical properties such as tensile, compression, flexural, Impact test of the prepared specimen have been evaluated as per the ASTM standards. The mechanical properties results depicts that the specimen prepared with chemically treated fiber gives more strength as compared to untreated fiber composites. The morphological study evidences the proper fiber used while preparing the hybrid composite material. The maximum tensile strength achieved in specimen is 73.48 MPa, compressive strength of 99.63 MPa, flexural strength of 77.50 MPa, Impact strength of 4.8 J/mm, Vickers hardness value of 59.6. The specimen prepared with chemically treated specimen has a higher percentage of water absorption than the untreated. This novel hybrid composite material can be used in automobile, aircraft, building, sports, and household applications.

“…Li et al [ 58 ] prepared high performance porous foams based on nanofibrillated cellulose (NFC) and ethanol, isopropanol, tert-butanol, and n-butanol followed by freeze-drying. They found that the foams prepared from NFC suspensions containing ethanol, isopropanol and n-butanol exhibited highly porous structures with a honeycomb-like cellular texture and well-defined pores comparing with foams based on tert-butanol/NFC, which exhibit a higher number of smaller size pores with irregular shape.…”

Wet foam can be used as a carrier in the manufacturing of lightweight materials based on natural and man-made fibers and specific additives. Using a foam forming method and cellulose fibers, it is possible to produce the porous materials with large area of end-using such as protective and cushioning packaging, filtering, hydroponic, thermal and sound absorption insulation, or other building materials. In comparison with the water-forming used for conventional paper products, foam-forming method provides many advantages. In particular, since fibers inside the foam are mostly trapped between the foam bubbles, the formed materials have an excellent homogeneity. This allows for using long fibers and a high consistency in head box without significant fiber flocking. As result, important savings in water and energy consumptions for dewatering and drying of the foam formed materials are obtained. In cushioning packaging, foam-formed cellulose materials have their specific advantages comparing to other biodegradable packaging (corrugated board, molded pulp) and can be a sustainable alternative to existing synthetic foams (i.e., expanded polystyrene or polyurethane foams). This review discusses the technical parameters to be controlled during foam forming of cellulose materials to ensure their performances as cushioning and protective packaging. The focus was on the identification of practical solutions to compensate the strength decreasing caused by reduced density and low resistance to water of foam formed cellulose materials.

Aluminium metal foams offer low density (∼10–15% of bulk material) possessing cellular structure that ensures unique features with high stiffens, better energy absorption, thermal and acoustic properties. Selection of different foaming agents for preparing AA6061 foam samples are indeed an industrial relevance for better control over porosity and its dimensions, strengths (tensile, flexural and compression) useful for distinguished applications. Three foaming agents such as wax powder, magnesium hydroxide, and titanium hydride are selected with varying 3–9 weight percentage to prepare metal foams viz. powder metallurgy technique. For the prepared foam samples the percentage porosity, pore dimensions (maximum pore size, and equivalent diameter) and strengths were examined. Wax powder foaming agent resulted with a maximum strength in foam samples compared to magnesium hydroxide and titanium hydride. Scanning electron microscope with energy dispersive spectroscopy analysis revealed that there is no evidence of foreign elements and confirm uniform distribution of porosity in the foam samples.
