In this regard, a data-driven framework was proposed in this paper to determine the layup rules to follow for minimizing PID. Two specific machine learning (ML) models were built. One is combined model of convolutional neural networks (CNN) and principle component analysis (PCA) technique for connecting the layup sequences and their corresponding PID. Another one is the symbolic regression model, as an explainable ML technique, to quantitatively evaluate this connection. With the training data generated from the robust numerical simulation, it is found that a proper asymmetry is the key intrinsic factor that makes a smaller PID as it will counteract with the contributions of other extrinsic mechanisms. More importantly, a formula for easy evaluation of the asymmetry is provided to assist in guiding the layup design considering PID constraints. The formula is applied on the design problem of double-double (DD) composites.

Thermogravimetric analysis (TGA) was first carried out in both nitrogen and air environments to understand the thermal stability and degradation behaviour of the CFRP material. Initial laser tests were conducted at 30 W and 40 W using a beam diameter of 3.46 mm to assess early-stage damage.

For the 98 W cases, the larger beam diameter required a 53 % longer exposure time to achieve perforation, highlighting the role of power density in damage progression. Post-irradiation analysis using scanning electron microscopy (SEM), ultrasonic C-scans, and micro-focused X-ray computed tomography (micro-CT) revealed fibre sublimation, matrix decomposition, cone-shaped perforations, and interlaminar cracking.
