Embodiment 1
[0026] Add the caprolactam monomer into the reaction kettle, heat up to 100°C to melt, then vacuumize and drain for 15 minutes, then add the initiator caprolactam magnesium bromide 0.6mol%, vacuumize and drain for 15 minutes, and finally add bis-acylated lactam-1,6 - Hexamethylenediamine 0.6mol%, mix well and then vacuumize for 10min. The above-prepared active material was poured into a mold with ramie fiber fabric placed, vacuumed to -0.05Mpa quickly, polymerized at a polymerization temperature of 160°C for 60min, and the mold was cooled naturally to obtain a composite material product.
Embodiment 2
[0028] Add the caprolactam monomer into the reaction kettle, heat up to 120°C to melt, then vacuumize and drain for 15 minutes, then add the initiator caprolactam magnesium bromide 0.6mol% and vacuumize and drain for 15min, finally add TDI 0.6mol%, mix well. The active material prepared above was poured into a mold with ramie fiber fabric placed, quickly evacuated to -0.05Mpa, polymerized at a polymerization temperature of 165°C for 60min, and the mold was naturally cooled to obtain a composite material product.
Embodiment 3
[0030] Add the caprolactam monomer into the reaction kettle, heat up to 100°C to melt, then vacuumize and drain for 15 minutes, then add the initiator caprolactam magnesium bromide 0.6mol% and vacuumize and drain for 15 minutes, then add 5% of the dried cellulose powder into the In the solution, stir well to make it evenly dispersed, and finally add 0.6mol% of bisacylated lactam-1,6-hexanediamine, mix well and then vacuumize for 10min. Pour the above-prepared active material into the preheated mold, quickly evacuate to -0.096Mpa, polymerize at a polymerization temperature of 160°C for 60min, and cool the mold naturally to obtain a composite material product.
