Experimental characterization of autoclave‐cured glass‐epoxy composite laminates: Cure cycle effects upon thickness, void content, and related phenomena

摘要: This article presents results from over 100 experimental autoclave curing fiber-glass-epoxy composite laminate runs. The primary objective was to verify shrinking horizon model predictive control—SHMPC—for thickness and void content control, using readily available secondary measurements. present analyze the extensive obtained through this verification. Seven series of runs (16 per series) were performed, with cure settings governed by partial- or full-factorial orthogonal array based design experiments. Through t-tests two-way analysis variance, it found that pressure magnitude had largest influence on content, while first hold duration/temperature, application duration, run delay influenced more than thickness. Thinner laminates lesser contents resulted before second temperature ramp. Prepreg age also affected content. Photomicrographs revealed not one large void, but clusters. Interrupted cycles significant reduction occurred during all cycle stages. percentage resin weight loss sides increased duration. Ten test indicated SHMPC met difficult targets minimizing
