Abstract

The invention discloses a plant fiber reinforced bio-based thermosetting resin composite and a preparation method thereof. Bio-based reactive solvent iosorbide-methacrylate is blended with acrylated epoxidized soybean oil to prepare bio-based thermosetting resin, and plant fibers, the bio-based thermosetting resin and an initiator are subjected to thermo-compression formation to obtain the plant fiber reinforced bio-based thermosetting resin composite. The plant fiber reinforced bio-based thermosetting resin composite and a plant fiber reinforced modified bio-based thermosetting resin composite prepared by the method have good bending strength, bending modulus and bending strain performance.

Description

technical field [0001] The invention belongs to the technical field of natural plant fiber-reinforced resin composite materials, and in particular relates to a plant fiber-reinforced bio-based thermosetting resin composite material and a preparation method thereof. Background technique [0002] In natural plant fiber reinforced polymer composites, the most commonly used thermosetting resins are epoxy resins, phenolic resins and unsaturated polyester resins. Generally, these thermosetting resins have good mechanical properties, chemical corrosion resistance and process performance, but the environmental and air pollution problems caused by the volatilization of added toxic substances (such as formaldehyde, styrene, etc.) during use has attracted great attention. In addition, the continuous depletion of petroleum resources has forced people to seek and develop new renewable bio-based resins. Acrylate Epoxidized Soybean Oil (AESO) is obtained by reacting soybean oil with acry...
