Epoxy composites reinforced with natural fillers such as flax fiber and linseed cakes (Rapid communication)

Abstract

Epoxy composites reinforced with flax fabric and modified with waste filler in the form of linseed cakes (LC) were prepared. Thermomechanical properties using the DMTA (Dynamic Mechanical Thermal Analysis), thermal properties using the TGA (Thermogravimetry) method, flexural strength, Charpy impact strength, Shore hardness and density of the composites were tested. The addition of small amount ground linseed cakes improved the value of the composite storage modulus. The introduction of a large amount of waste additive reduced the impact strength of composites, without affecting their thermostability and hardness.
