Pengaruh Waktu Perendaman NaCl terhadap Ketangguhan Impak dan Morfologi Patahan Komposit Serat Sansevieria Bermatriks Epoksi
Abstract
Serat Sansevieria berpotensi digunakan sebagai penguat komposit berbasis polimer. Penelitian ini bertujuan menganalisis pengaruh waktu perendaman serat Sansevieria dalam larutan natrium klorida (NaCl) selama 5, 7, dan 9 hari terhadap ketangguhan impak dan morfologi patahan komposit bermatriks epoksi. Serat yang telah direndam dikeringkan dan digunakan sebagai penguat komposit melalui metode continuous lay-up. Pengujian ketangguhan dilakukan menggunakan uji impak Charpy, sedangkan morfologi patahan diamati menggunakan mikroskop optik. Hasil pengujian menunjukkan bahwa rata-rata ketangguhan impak meningkat seiring bertambahnya waktu perendaman, yaitu sebesar 0,0400 J/mm² pada 5 hari, 0,0633 J/mm² pada 7 hari, dan 0,0840 J/mm² pada 9 hari. Dengan demikian, perendaman selama 9 hari menghasilkan rata-rata ketangguhan impak tertinggi di antara variasi yang diuji. Pengamatan morfologi patahan menunjukkan adanya fitur fiber pull-out dan fiber break yang menggambarkan mekanisme kerusakan komposit. Namun, pengamatan visual tersebut belum cukup untuk memastikan peningkatan adhesi serat–matriks secara kuantitatif. Hasil penelitian menunjukkan bahwa variasi waktu perendaman NaCl berkaitan dengan perubahan ketangguhan impak komposit pada rentang pengujian yang dilakukan. Penelitian lanjutan diperlukan untuk mengevaluasi variasi waktu perendaman yang lebih luas dan memperkuat analisis statistik guna memperoleh dasar yang lebih kuat dalam menentukan kondisi perlakuan yang sesuai.
Kata kunci: Sansevieria, NaCl, ketangguhan impak, morfologi patahan, komposit epoksi.
