Composite having plant fiber textile and fabricating method thereof

A method of fabricating a plant fiber reinforced biomass resin based foam laminate comprising a biomass epoxy resin and a plant fiber felt supporting the biomass epoxy resin, the plant fiber felt including ramie, flax, hemp, or jute plant fiber and having a weight content of 40% to 60%, the method comprising:

• preparing the plant fiber felt with a thickness of 0.1 to 5 mm from a natural fiber of a plant selected from ramie, flax, hemp, or jute;
• performing a fire retardation treatment to the plant fiber felt by impregnating the plant fiber felt into a first aqueous solution including a fire retardant, the fire retardant including a nitrogen phosphor based fire retardant;
• performing a compatibility promotion treatment to the plant fiber felt by impregnating the plant fiber felt into a second aqueous solution including a coupling agent, the coupling agent including a silane coupling agent or a potassium permanganate solution, the silane coupling agent being at least one selected from the group consisting of vinyltriethoxysilane, γ-amino propyltriethoxysilane, or γ-(2,3-epoxy-propoxy) propyltrimethoxysilane;
• preparing a micro-capsule foaming agent including a capsule shell formed from polylactic acid and alkane enclosed in the capsule shell, the micro-capsule foaming agent having a particle size of 5 μm to 50 μm, the alkane having an amount enabling the micro-capsule to expand by 50 to 100 times in term of volume after being heated up to 100° C. to 180° C.;
• mixing and grinding a Maleated rosin based epoxy resin curing agent with an epoxy resin to form a fine powder of a partial biomass epoxy resin having a particle size of 10 μm to 100 μm;
• adding the micro-capsule foaming agent in a content of 5% to 15% to the fine powder of the partial biomass epoxy resin to prepare an aqueous suspension;
• after the fire retardation treatment and the compatibility promotion treatment are performed on the plant fiber felt, fully impregnating the plant fiber felt into the aqueous suspension and drying the aqueous suspension to obtain a foam pre-impreg;
• and
• heating the foam pre-impreg at 100° C. to 180° C. for 10 to 15 minutes, so as to expand the plant fiber felt by 5 to 8 times in a thickness thereof to obtain the continuous plant fiber reinforced biomass resin based foam laminate.

A plant fiber reinforced biomass resin based foam laminate comprising:

• a biomass epoxy resin;
• and
• a reinforcement body supporting the biomass epoxy resin, and including a plant fiber selected from ramie, flax, hemp, or jute plant fiber, the reinforcement body having a weight content of 40% to 60%, wherein the reinforcement body is impregnated into a first aqueous solution including a coupling agent for a coupling treatment and a second aqueous solution including a fire retardant for a fire retardant treatment,
• the coupling agent includes a silane coupling agent or a potassium permanganate solution, the silane coupling agent being at least one selected from the group consisting of vinyltriethoxysilane, γ-amino propyltriethoxysilane, or γ-(2,3-epoxy-propoxy) propyltrimethoxysilane, and
• the fire retardant includes a nitrogen phosphor based fire retardant, wherein the biomass epoxy resin includes:
• a biomass epoxy resin,
• a Maleated rosin based epoxy resin curing agent, and
• a micro-capsule foaming agent including a polylactic acid shell and an alkane enclosed in the polylactic acid shell, wherein the micro-capsule foaming agent expands by 50 to 100 times by volume after being heated up to 100° C. to 180° C.
