The governing equations account for fiber reinforcement, material porosity, and thermal relaxation effects. Exact solutions for displacement, temperature, and stress fields under pulsed laser heating are obtained using normal mode analysis. The MGT framework captures finite thermal wave speeds and three-phase-lag effects, offering more realistic predictions than classical thermoelastic models for short-pulse laser interactions. Numerical simulations, evaluated at different time scales, demonstrate the pronounced influence of reinforcement parameters, porosity, and laser pulse characteristics on thermoelastic wave propagation. Results highlight strong thermo-mechanical coupling, with porosity emerging as a key factor in energy dissipation.
