Experimental description of aging of palm oil kernel shell powder/epoxy composite

Abstract

Aging of polymeric materials is one of the application limits of these materials. Describing the degradation will help determine the life cycle of the product, describing the degradation process is so important in determining possible application spheres. The paper focuses on the degradation of the matrix composite in the form of epoxy resin and palm oil kernel shells (PKS). Handling bio-waste arising from oil palm processing is a great challenge, material use of these commodities is an interesting alternative to other options. The filler was of irregular particle size up to 100 μm the filler concentration in the matrix was 2.5, 5.0 and 10.0 wt.%. Renewable resources are increasingly promising options for sustainable material engineering. The presence of organic microparticles can optimize some mechanical characteristics and reduce the cost of the resulting material. Microscopy was used to assess interphase interference and microscopic analysis of the surface and particle shape. The contribution showed that the presence of organic particles in the matrix did not significantly affect the decrease of mechanical properties due to degradation in laboratory conditions. Specifically, these were experiments in the climatic chamber where humidity and temperatures varied between + 70 ° C and-40 ° C for 840 hours. The decrease in shear strength on steel adherence reached 3.99 MPa in the unfilled resin and 5.77 MPa (10% PKS) in the palm kernel shell resin.
