Bu çalışmada ısıl enerji depolama özellikli ve
biyobozunur esaslı FDM/çam kozalağı kompozitleri doğrudan emdirme yöntemi
kullanılarak hazırlanmış ve analiz edilmiştir. Palmitik asit ve miristik asit
FDM, doğal çam kozalağı, kompozit matrisi olarak çam kozalağı kullanılmıştır.  Üretilen kompozit malzemelerin morfolojik, termal
ve kimyasal yapısını incelemek için sırasıyla; taramalı elektron mikroskobu
(SEM), diferansiyel taramalı kalorimetre (DSC), Fourier dönüşümlü kızıl ötesi spektroskopisi
(FTIR) kullanılmıştır. Üretilen kompozitlerin termal dayanımı 100^oC’de
test edilmiştir. DSC analizleri sonucunda üretilen miristik asit ve
palmitik asit kompozitlerin erime noktası ve gizli ısı depolama kapasitelerinin
sırasıyla 51,82°C: 74,60J/g ve 59,36°C: 71,22J/g olduğu belirlenmiştir. Tüm analiz
sonuçlarına göre üretilen FDM/çam kozalağı kompozitlerinin ısıl enerji depolama
uygulamaları için uygun bir enerji depolama materyali olduğu belirlenmiştir.
