“…Both composites showed a small exothermic peak from 200 to 225°C that may correlate with the thermal degradation of MW. [ 30,33,59 ] The T g of the composites with native and acetone‐treated MW was observed at 231.9 and 228.5°C, respectively, with no statistically significant difference between these two values.…”

Milkweed floss was used as a reinforcement to develop lightweight epoxy composites with enhanced thermal insulating properties. Seed fibers from Asclepias Syriaca harvested in Quebec were used for this study. Some fibers were treated with acetone to remove their protective hydrophobic coating.Epoxy resin was blended with 15% w/w of native or acetone-treated milkweed floss to form prepregs. The prepregs were casted into molds, degassed, and compressed to produce the composites. The composites were passed through a post-curing phase before characterization. The composites and the epoxy resin alone were characterized to determine their density, porosity, thermal conductivity, thermal degradation, mechanical resistance, and thermo-mechanical behavior. The composites reinforced with native or acetone-treated milkweed floss were 7.4% and 10.3% lighter than the epoxy resin, respectively. The specific elastic modulus of the resin increased by 9.6% and 20.1% with the addition of native or acetone-treated fibers, respectively. The thermal conductivity of the epoxi decreased by 7.8% and 15.6% with the use of native or acetonetreated milkweed floss, respectively. Due to their low weight and reduced thermal conductivity, the milkweed-reinforced epoxy composites may find applications in the production of structural and insulating elements for vehicles and buildings.

This study investigated the influence of fiber content, temperature, and relative humidity on the thermal insulation properties of nonwoven mats made of seed fibers from Asclepias Syriaca, commonly known as milkweed floss. Nonwoven mats with a 1-inch thickness were produced by uniformly arranging milkweed fibers within a mold. Various quantities of fiber were employed to obtain nonwoven mats with a fiber content ranging from 5 to 35 kg/m3. Thermal conductivity and thermal diffusivity were measured across diverse relative humidity levels and temperatures. Simultaneously, milkweed floss samples were exposed to identical environmental conditions to assess the moisture regain and specific heat capacities of the fiber. The specific heat capacity of milkweed and thermal conductivity of the nonwovens exhibited a linear increase with temperature. The thermal diffusivity and thermal conductivity of the nonwovens decreased with rising fiber content. The thermal insulation properties of the nonwovens remained partially stable below 30% relative humidity but substantially deteriorated at higher levels. The nonwovens exhibited optimal thermal insulation properties at a fiber content between 20 and 25 kg/m3. The results of this study highlighted several technical advantages of employing milkweed floss as a sustainable and lightweight solution for thermal insulation.
