Question & Answer to the Presentation

Question from Prof. Medyan Riza 2022.12.21 14:47:54 I am very interested in your research sir, I would like to ask: 1. What is the novelty of this research work ? 2. What is the particle size of nanosilica used as filler in the manufacture of GFRP composites? Replies: Reply from Mr. Willy Akhsani Taqwim 2022.12.21 15:13:46 thank you Prof. Medyan Riza, is a good question 1. The novelty of this research is to combine two types of filler (pumice based nanosilica and sodium silicate) as a medium to maintain mechanical characteristics in the form of impact strength on GFRP composites. this is done with the aim of obtaining fire-resistant GFRP but still able to maintain the mechanical characteristics of the GFRP itself. 2. The nanosilica particle size used in this study is 74nm
