Measurement results of surface roughness after hand finishing of FRP products with a textured surface【Document】

Evaluation from two perspectives: micro assessment of surface roughness and macro assessment of surface profile!

This document is a technical report that describes the evaluation of surface roughness and surface profiles of different samples made by hand lay-up, which have three surfaces: the release surface, hand-finished surface, and molded surface. In conclusion, the surface roughness values for Ra, Rz, and Pt improved by approximately 77 to 85% compared to the release surface. Upon examining the profile of the flat surface, it was found that the irregularities observed on the release surface were significantly reduced due to hand finishing, and the parallelism improved by 45%. 【Contents】 ■ Evaluation Preparation and Methods - Preparation of evaluation samples - Surface roughness measurement - Surface profile measurement ■ Results - Preparation of evaluation samples - Surface roughness measurement - Surface profile measurement ■ Discussion - Surface roughness due to hand finishing - Inclination of Surface sample C in the surface profile *For more details, please download the PDF or feel free to contact us.
