Webb22 maj 2024 · The polymer matrix used for reinforcement is thermoplastic, thermosets, and polymers derived from natural resources. The composites can be made by various processing techniques such as extrusion, compression, hand lay-up, etc. WebbThe thermoset matrix is only partially cured to allow easy handling; this B-Stage material requires cold storage to prevent complete curing. B-Stage pre-preg is always stored in cooled areas since heat accelerates complete polymerization. Hence, composite structures built of pre-pregs will mostly require an oven or autoclave to cure. feminism and philosophy
