Composite materials with unsaturated polyester matrix reinforced with natural fibres were developed to make biodegradable composite materials so that the waste does not damage the environment. Regarding mechanical strength, natural fibre-based composites are still lower in mechanical strength than composite materials with synthetic fibre reinforcement. These weaknesses include easy cracking when hit because they are brittle and have a small plastic deformation area. Some actions that will be carried out in this study are the addition of pineapple fibres with unsaturated polyesters that can form composites that are resistant to cracking. The addition of pineapple fibers to unsaturated polyesters up to 20% can have the highest fracture strength with a value of K1C = 1.733 MPa.m0.5, whereas pure unsaturated polyester without a mixture of pineapple fibres only has a fracture strength of K1C = 0.779 MPa.m0.5. From the results of the study, the addition of pineapple fibres can increase the fracture strength of polyester materials by 222.47%.

Conclusion

From the research conducted, it was reported that the success of determining the right composition of a composite material mixture made of an unsaturated polyester matrix with the addition of pineapple leaf fiber to increase the crack resistance of unsaturated polyester polymers into crack-resistant composite materials.The highest performance was achieved with a 20% pineapple leaf fiber mixture.This research increased the toughness and crack resistance of the UP material treated with the addition of the SN mixture by 222.

Future Research

Penelitian lebih lanjut dapat dilakukan untuk menguji pengaruh variasi jenis serat alami lain, seperti serat sabut kelapa atau serat bambu, terhadap kekuatan patah komposit poliester. Hal ini akan memperluas pemahaman tentang potensi serat alami sebagai pengganti serat sintetis dalam aplikasi komposit. Selain itu, studi mendalam mengenai perlakuan permukaan serat nanas, seperti penggunaan metode kimia atau fisik, dapat dilakukan untuk meningkatkan ikatan antara serat dan matriks poliester, sehingga menghasilkan komposit dengan kekuatan patah yang lebih tinggi. Terakhir, penelitian dapat difokuskan pada pengembangan model matematis yang akurat untuk memprediksi kekuatan patah komposit serat nanas-poliester berdasarkan komposisi material dan parameter proses manufaktur, yang akan sangat berguna dalam desain dan optimasi komposit untuk aplikasi rekayasa tertentu. Penelitian-penelitian ini diharapkan dapat memberikan kontribusi signifikan dalam pengembangan material komposit berkelanjutan dan ramah lingkungan.
