AB  - In recent years, there has been an increasing need for materials that are 
      environmentally friendly and have functional properties. Polylactic acid (PLA) is 
      a biomass-based polymer, which has attracted research attention as an 
      eco-friendly material. Various studies have been conducted on functionality 
      imparting and performance improvement to extend the field of application of PLA. 
      Particularly, research on natural fiber-reinforced composites have been conducted 
      to simultaneously improve their environmental friendliness and mechanical 
      strength. Research interest in hybrid composites using two or more fillers to 
      realize multiple functions are also increasing. Phase change materials (PCMs) 
      absorb and emit energy through phase transition and can be used as a micro 
      encapsulated structure. In this study, we fabricated hybrid composites using 
      microcapsulated PCM (MPCM) and the natural fibrous filler, kenaf. We aimed to 
      fabricate a composite material with improved endothermic characteristics, 
      mechanical performance, and environmental friendliness. We analyzed the 
      endothermic properties of MPCM and the structural characteristics of two fillers 
      and finally produced an eco-friendly composite material. The PCM and kenaf 
      contents were varied to observe changes in the performance of the hybrid 
      composites. The endothermic properties were determined through differential 
      scanning calorimetry, whereas changes in the physical properties of the hybrid 
      composite were determined by measuring the mechanical properties.
