and shifted designs from stability to yield limited across T i . However, the inner PEEK liner yielding still dominated failure at high temperature due to temperature dependent strength decline. Overall, temperature resilient TCPs could incorporate laminates that combine axial and hoop plies to distribute load demands and moderate thermal mismatch stresses.
