A high heat storage capacity form-stable composite phase change material (CPCM) with enhanced flame retardancy that integrated modified glass fibers with form-stable PCM was proposed. The modified glass fibers were wrapped by a composite flame retardant coating. The thermal and flame retardant properties of the CPCM were measured and compared to other CPCM samples. The results of vertical burning test indicated that the glass fibers improved the mechanical properties of the CPCM and prevented it from fracturing during the burning process. The modified glass fibers could further improve the flame retardancy of CPCM, and V-0 burning rating was achieved while the content of paraffin was maintained at 70 wt%, which means the proportion of flame retardants could be reduced. TGA results showed that the modified glass fibers could enhance the thermal stability and retard the degradation process of the CPCM, and the char residue was increased to 15.3%. Thermal cycling results indicated that the CPCM has good thermal reliability. The results of cone calorimeter test indicated that the peak heat release rate (PHRR) of flame retardant form-stable CPCM dropped by 58.8%, and the combustion rate could be greatly slowed down due to the protection of carbon layers formed by modified glass fibers. In addition, the thermal conductivity of CPCMs were greatly enhanced and the CPCM has good thermal reliability.

提出了一种具有高阻燃性的高储热形状稳定复合相变材料（CPCM），该材料将改性玻璃纤维与形状稳定PCM集成在一起。改性玻璃纤维被复合阻燃涂层包裹。测量了CPCM的热和阻燃性能，并与其他CPCM样品进行了比较。垂直燃烧试验的结果表明，玻璃纤维改善了CPCM的机械性能，并防止了其在燃烧过程中破裂。改性玻璃纤维可以进一步提高CPCM的阻燃性，在石蜡含量保持在70 wt％的同时达到V-0燃烧等级，这意味着可以降低阻燃剂的比例。TGA结果表明，改性玻璃纤维可以提高CPCM的热稳定性，延缓CPCM的降解过程，炭渣含量增加到15.3％。热循环结果表明，CPCM具有良好的热可靠性。锥形量热仪的测试结果表明，阻燃形式稳定的CPCM的峰值放热率（PHRR）下降了58.8％，并且由于保护了改性玻璃纤维形成的碳层，燃烧速率可以大大降低。另外，CPCM的导热率大大提高，并且CPCM具有良好的热可靠性。锥形量热仪的测试结果表明，阻燃形式稳定的CPCM的峰值放热率（PHRR）下降了58.8％，并且由于保护了改性玻璃纤维形成的碳层，燃烧速率可以大大降低。另外，CPCM的导热率大大提高，并且CPCM具有良好的热可靠性。锥形量热仪的测试结果表明，阻燃形式稳定的CPCM的峰值放热率（PHRR）下降了58.8％，并且由于保护了改性玻璃纤维形成的碳层，燃烧速率可以大大降低。另外，CPCM的导热率大大提高，并且CPCM具有良好的热可靠性。
